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

Double Patch Regular Polyhedron The rectangle 94*68 mm, the sides of the cutting plane 28 and 16 mm rack Diameter 6 mm. each patch has an input impedance of 100 Ohms, between 0.5 *Lambda of the connecting line. Obtained by parallel connection of 50 Ohms. And cool chart SWR the broadband is a patch in the form of an pseudo- ellipse with eccentricity 0.8, 2 Patches of narrow-band, but with the increase of the gap band of operating frequencies increases at 0.1 Lambda reaches 10/11 %. When band gaps, increases the ability of multi-mode excitation. With the increase of the gap increases and the value of the input impedance. Based on this information, can built a patch with a gap from the reflector is 15 mm. The line length is 0.5 L, so its width is not critical. In this project its width is about 2 mm d = 1 mm The gap( between the surfaces) 15 mm width to reflector Conn. line 13 mm. the distance between the two coherent emitters choose, usually based on two criteria. Or the maximum gain, then it's 1 lambda or a little more. Or at a minimum side lobes, then it is less than lambda, about 0.7/0.8.

Radiation patterns and gain measurements on 1.0, 1.5, and 2.0 lambda backfire Yagi antennas are given. The backfire antenna was tested for two dipole feed locations, and variations in the diameters of the two planar reflectors forming the backfire cavity. The optimum dimensions of the three test antennas are tabulated. The frequency bandwidth of the backfire antenna is limited to several percent due to impedance matching. The backfire antenna should find application in broadside arrays where conventional endfire antennas are presently used. 19680012807.pdf

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.

This is the simplest type of antenna from a theoretical point of view.

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:

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

,,,no, it doesn't depend on the material...!!! ,,,but the most important thing is that the vibrating disc should be made of weldable material...!!!

Here are some quick notes about the parabolic type dish antennas you might find. The actual antenna is a normal half wave dipole with an integrated balun and is located inside the sealed plastic cover. The mesh screen is the reflector which concentrates the RF energy onto the antenna. That is how dish antennas increase the received or transmitted power level. Also, wireless cable service providers frown upon giving away their used dishes as they think you're going to steal cable service.

Two long arms are connected in the shape of V to make a V-antenna. The two long arms are excited with 180˚ out of phase. As the length of these arms increases, the gain and directivity also increases. The following figure shows a V-antenna with the transmission line impedance z=200 Ohm and the lengh of the arm 0,8*lambda, making an angle Φm with the axis, which is called as apex angle.material-FR4 #1.5mm. The main advantage of a V-shaped antenna is its relatively small vertical radiation angle, which is especially important for establishing long-distance communications.

A method to improve the gain of axial-mode helical antenna is proposed. This method involves a parasitical circular metal disk,which is installed on the front of general axial-mode helical antenna and is apart from the helical line. A circular current whose phase lags behind that of helical line current appears,which brings a more concentrated radiation field. Consequently,the antenna gain is improved, Based on the simulation results,an antenna array model fed independently is proposed.This model gives an excellent explanation of the radiation characteristic of helical antenna, Both the simulation and experiment results show that for obtaining the same gain,the antenna length in this new method is only 71% of that in traditional helical antenna.The reduction of antenna length favors the miniaturisation of antenna. In addition, this method has a little effect on the bandwidth of antenna, so it can be widely used in the design of helical antenna element and array.

,,okay, I will try...!!! I use cst.
