  2. 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:
  3. 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.
  4. 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.

  5. ,,okay,but there is still something wrong with the H1 and H3 dimensions....!!!
  6. 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...

  8. Can this be true...??? https://www.thanksbuyer.com/16dbi-2-4ghz-wifi-antenna-directional-antenna-1-5m-extension-cable-without-wireless-network-card-90104?limit=60
  9. Yes, that's what it would be like...
  10. 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.
  11. After an idea of Vman... Sector Antenna 2442mhz.cst
  12. 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.

  13. AndreyKot, ...the Cantennator program is not very good, so please view these forum posts... I will try to make an optimal simulation for this frequency(800 MHz).
  14. ,,,it's possible that way too...
  15. ,,,now I'm trying to reduce it a little but with the same results...
  16. Yes, if you find something like that....
  17. Have a router with built in modem Huawei B683. Used in the country, the range is 2400 there clean. All anything, but Wi-fi gives it worse than a smartphone, the plot is not even enough, although installed in the wooden deck solder the pigtails and screw conventional pipettes from any router.Track is better to cut, as this connector is not found, and if found, it will break with the first poke. In extreme cases, all easy to restore in place
  18. U.FL (‘U’ stands for ultra-small and ‘FL’ is just a series name assigned by Hirose) connectors are commonly used in gateways and end devices where space is of critical concern (similar: I-PEX, IPX, etc).
  19. ,,,okay,I will try....!!! Yes, so be it...???
  20. Almost done, but not very good... ,,and with more patches...
  21. ,,,not yet, but in the future...!!!
  22. 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.
  23. In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis. Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.
  24. So you mean to increase the number of directors.../??
