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.

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:

In this POST, we investigate a wideband magnetoelectric dipole antennA miniaturized by folding. In the proposed design, a folded L‐shaped electric dipole is used instead of the conventional half‐wavelength horizontal electric dipole, and a pair of vertically folded shorted patches act as a magnetic dipole, producing a miniaturized radiator. Furthermore, a small‐size U‐shaped reflector replaces the traditional large‐size planar reflector, resulting in a decrease in the low end of the frequency band, while the high end of the frequency band remains almost unchanged. A better impedance matching is also obtained over the entire operating frequency band. Ultimately, a miniaturized overall structure and a wide bandwidthare obtained simultaneously. The overall size of the proposed antenna is only 0.25λ×0.25λ×0.12λLLL(whereλL is the longest operating wavelength), which is 82% smaller than the size of the original design, but the proposed antenna can still obtain a large bandwidth of 120% (1–4GHz) for VSWR<2. Furthermore,stable radiation patterns are realized with an average gain of 5 dBi within theoperating frequency band Our friend Clanon previously posted the following...

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.

Waveguide slot antennas are a type of microwave antenna that use a hollow metal tube, called a waveguide, to transmit and receive electromagnetic waves. They have slots cut along the length of the waveguide, which act as radiating elements. Waveguide slot antennas have some advantages over other types of antennas, such as high efficiency, low loss, and wide bandwidth. Single Sided 8 Slots Waweguide...41x20x360mm....

The ANT010PN is a 10dB directional panel antenna, capable of precisely broadcasting a 2.4GHz wireless signal across a great external distance. This antenna comes with its own flush wall-mount for easy installation onto a wall or pole and is fitted with an N-Type socket connector. The ANT010PN is typically used with outdoor wireless equipment such as WiFi Access Points to point a 2.4GHz signal across a longer distance than would normally be feasible to a very specific point, such as a single WiFi client or a second receiving antenna.
