,,,clanon,can you give more information about this antenna....????

I don't think so, but you have to try it...!!!

I think the antenna for this frequency will be a bit big.(270x750mm)

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...

It would be good if the focal length(F/D) was also shown for each antenna grid...!!!

There are no differences, except that the feed must be performed differently, to ensure a good impedance match. One can even build rectangular plate Yagi-Uda"s, and make the elements slot antenna elements. Also, a different feed is required for that.

Compact sector antenna WiFi Ubiquiti airMax Sector 5G 17-90 designed for installation where the placement of a full-sized devices is not possible or desirable. This WiFi antenna is almost twice shorter than the "large" Sector airMax and weighs just over 1 kg. Despite its modest dimensions, the device has retained all the key characteristics of the family of these WiFi antennas. Ubiquiti airMax Sector 5G 17-90 has the gain of 17 dBi and a wide sweep of 90°. WiFi antenna mounts to wall or post by means of special fastenings.

The BAS-2346 FLAT MINI MIMO antenna is designed for equipment operating in the frequency range of 690-960 MHz / 1800-3600 MHz and having ports for connecting external antennas with MiMo support (Multi input multi output) The antenna is connected by two 5-meter-long RG-58A/U cables with SMA connectors. If necessary, the cable can be extended in the same way as the wave one with a resistance of 50 Ohms. You may need an SMA-CRC9 adapter (TS9, FME, etc.) to connect to the hardware.Adapters and an additional cable are purchased separately. The antenna can be mounted on a mast with a diameter of 20 mm to 50 mm or on a wall bracket. A distinctive feature is the extended frequency range, including 3.5 GHz. The location of the antenna:Outer Supported communication standards:GSM (GPRS/EDGE), 3G (HSPA/HSPA+/WCDMA), 4G (LTE800, LTE1800 LTE2700, WiMax) Operating frequencies, MHz:690-960 MHz / 1700-2700 MHz /3400-3600 MHz Gain factor, max., dBi:7dB / 12dB / 7dB The standing wave ratio on voltage not more than:1.5 Wave resistance, Ohms:50 Cable length, m:5 Connector type:2 x SMA Overall dimensions (without mounting unit), mm:160x170x75 Weight, not more than, kg:1 Package dimensions, mm:175x215x100 Package weight, kg:1.1

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.

,,,what is the password...???

PETRA BB MIMO 2x2 UniBox is an antenna combined with a large sealed box (UniBox) which you can put any 3G/4G modem and even router. The antenna is provided with connectors - SMA-male. Included are two adapters to connect 3G/4G modems (the type of adapters to choose). The connection of modem to PC or router located in the room is via a USB extension cable. System UniBox - protects the modem from adverse weather conditions! Advantages: Universal antenna with excellent gain and operating in all high-speed standards Reliable fastening of the modem in the box Quality connectors for connection of modem and antenna Quality adapters with minimal losses Hermetically sealed Hardy and ultrafiol case material The possibility of repeated Assembly and disassembly of the box All set to launch the modem

I wonder why you make a radiator with a diameter of 537 mm, when you better use a parable from the trade....???!!! ,,, a lot of work for nothing....!!!

,,,a pretty good version with round patches... ,,,,by increasing the reflector we increase the antenna gain....

yes

For receiving, you can safely use either. Losses from using 75ohm would be negligible. Only for TX you want 50ohm.

,,,only on 50 Ohm impedance...!!!

,,,watch this...

yes

diameter=940 mm...it's very large...!!!

,,,this ring works as parasitic director...!!

,,,no,this antenna belongs to user Harry36...!!!

,,,for those who want to build a Kathrein a ntenna...

,,,,eco32, it would be good if you could give some dimensions...!!!
