The central contact is not short, it is 5.77 mm. I will do a simulation with this connector. SMA Jack.cst

Hy buddy...!!! It would be preferable to connect the antenna to the reflector with wire

This project is dedicated to Doyt R. Hoverman (b.1913), the man who created and did the early work on the Hoverman antenna at a time when antenna modeling programs did not exist. His work would have been entirely created and improved by field testing, trial and error, and with a great amount of calculation without the benefit of electronic devices. Without his efforts, our work would not have been. Doyt Hoverman passed away in December, 1989 at Van Wert, Ohio, USA. Technical data Simulation With insulating spacers

Antenna BDM-2 is designed for outdoor use, although often applied in residential/non-residential premises. Experts recommend the use of antenna BDM-2, as a client equipment in all cases, build wireless networks of small and medium-range. The original of the antenna is with a 64mm diameter cylindrical vibrator

I think you don't need to connect directly the antenna to the phone anymore, you can have your phone connected to the access point. ,,,or if you want watch this video on youtube....

The cross antenna is a medium gain and circular polarization structure made of a conductor or a strip line over the ground plane following a cross contour of four or more branches.The construction repeatability is verry easy as well the facility to obtain 14dBi gain in a small antenna.

We've shared tons of ways to boost your home Wi-Fi, but if you need something a bit more powerful, this DIY antenna can stretch your wireless network much further. Simply use this sardine cane box from which the cover is used for patch antenna... This box is ideal for the construction of antennas in the 5 GHz band and beyond...

COMPARISON BETWEEN CIRCULAR AND RECTANGULAR DESIGN OF YAGI PATCH ANTENNA Following table2 gives comparison of results of Rectangular and Circular patch antenna: From simulation result of circular and rectangular yagi patch antenna it is clear that the performance parameter changes as change in geometry. COMPARISON OF SIMULATION ON DIFFERENT SOFTWARE Following table gives comparison of result on different software: From above table it is clear that performance of antenna parameter vary with simulation software .HFSS gives the improved results. CONCLUSION In previous work same antenna was designed in CST MICROWAVE studio software but the result were not satisfactory. Same design in HFSS gives improved result. With this design we get improved result of return loss ,F/B ratio, but gain result is not satisfactory. Gain can be improved by changing some dimension. For wifi antenna is the best solution previous work has done with CST software , but some antenna is proposed with HFSS software which has given the improved result and lower F/B ratio. Dielectric constant used for this antenna is FR4 epoxy which is easily available in market. By changing the shape, dimension the simulation will be performed and the result will be taken and with best result antenna will be fabricated.

Wifislax 2017 - a boot disk with a set of tools that will help test your wireless networks, identify and resolve different vulnerabilities in them. Contains a large number of drivers for the network cards from different manufacturers integrated into the Linux kernel and provides their support. Wifislax 2017 – a high level of specialized system-a software tool for security analysis of wired and wireless networks. Is a LiveCD preloaded with Slackware. Can be used for analysis and verification of security systems LANs of different types, the study and evaluation of Wi-Fi networks, as well as in forensic purposes. Wifislax 2017 out of the box comes with a huge number of drivers for network cards, both wired and wireless types, is integrated in the kernel Linux that provides native support for the vast majority of currently available network devices from different manufacturers. Wifislax 2017 is based on a code system of SLACKWARE (in earlier versions of the distribution was used a combination of SLAX and PORTEUS) and can be installed on a hard disk for permanent use. Being a "modular" operating system, it supports the expansion of functionality using the XZM-file. A GUI is provided by three related systems – KDE 4 (installed as default), Xfce and Openbox. In the distribution uses multiple cores – standard and PAE, you can switch between. Running the system with the USB stick: For recording, use the program UNetbootin, he checked, everything works fine. http://foro.seguridadwireless.net/live-wifislax/wifislax64-1-1-final-para-descarga-64220/ Modulos extra para wifislax64-1.1 http://foro.seguridadwireless.net/live-wifislax/modulos-extra-para-wifislax64-1-1/

TP-Link CPE210/220 is a 2.4Ghz outdoor access point similar to Ubiquiti NanoStations. There is also a 5GHz Version of this AP, the TP-Link CPE510/520. The device has a built-in 12dBi 2x2 dual-polarized directional MIMO antenna with a beamwidth of 65° (H-Plane) and 35° (E-Plane)

Antennas are essential wherever wireless communication required. They are the indispensable link between the contained signal and the “ether”. CST provides a variety of tools for each stage of the antenna design flow to study and improve your design. Antennas are used in a vast variety of applications, and thus take come in a vast variety of form factors and radiation mechanisms. The range of simulation methods in CST MWS allows the engineer to choose the best technique for each application. The transient solver could be best for wideband or planar antennas, the frequency domain solver may be more suitable for electrically small antennas, while the integral equation solver can efficiently simulate electrically large or wire antennas. Antennas never operate in isolation, but are attached to a feed network. CST DESIGN STUDIO™ (CST DS) allows the hybrid co-simulation of the effect of an attached circuit on the antenna performance. Installation of an antenna in a device or on a platform makes its analysis even more complex. The System Assembly and Modelling framework in CST DS allows the user to set up coupled simulations which can combine different solvers automatically by making use of field sources. Finally, powerful automated post-processing allows you to extract every magnitude of interest for an antenna designer – nearfield plots, SAR, phase center, directivity or farfield gain for single antennas or arrays - and to process those data further for use in parameter sweeps or optimizations in order to improve the performance of your design. Few pictures started...

It was interesting to design a small and lightweight antenna from available materials for FPV. After looking at what is available in household stores, I decided to stop at zinc/brass for the antenna elements and a canister cover as a radom. And so everything is in order - as it seemed to me, a lid from paint cans / mounting foam / air fresheners is perfect for radom. Its diameter is 77 mm external and 84 mm internal. Height from 12 to 40 mm. Material-polypropylene. Based on this, the dimensions of the entire structure were selected. you will need brass / galvanized 0.25 mm thick, brass tube diameter 4 mm external (wall thickness 0.25 mm), screw m3 -40 mm. cap nut m3, SMA connector, pipe cutter, metal scissors, drills with a diameter of 1.4 and 3 mm. The reflector is made of sardine cans. General view of the structure and results:

Single band IEEE 802.11 a/n standard High gain patch antenna Frequency (MHz) : 5150-5825 Peak Gain (dBi) : 10.0 VSWR : 2.0 : 1 Dimension (mm) : 76 x 72 x 3.8 Connector : IPEX MHF I Cable Length (mm) : 50 (customized) It seems to work well on the 5.6 GHz frequency.

This antenna is designed for use on mobile and stationary objects. Antenna works with any devices in the range of 790÷960/1700÷2700 MHz (USB modems, repeaters, amplifiers, etc.). Thanks to a wide band antenna capable of operating in the most skorostnyh the mobile communication standards, with a maximum Internet speed up to 300 MB/s For the implementation of the MIMO mode, it is recommended to use two such antennas.
