A horn antenna is one of the most commonly used antenna types for a focused antenna. However, the horn antenna is limited by its dimensions, which must have a certain size relative to the wavelength in order to work properly and efficiently. Since this will typically be too large to fit into the flange, a dielectric lens antenna with reduced dimensions is developed. The lens has the spherical form which is able to enhance the gain by making use of guided surface waves. The antenna is fed by a circular waveguide and at the boundary of the dielectric half space. A stepped impedance transformer has been introduced in order to provide broadband input matching impedance. Dielectric rod antennas refer to traveling wave antennas with a slow phase velocity (vf< s). They are used at the border of the centimeter and decimeter wave ranges in the frequency band from 2 to 10 GHz. Dielectric lenses are made of materials with high dielectric constants, such as polystyrene, polyethylene, and plexiglass. They can be integrated with various types of feeds, such as horn antennas, microstrip antennas, and waveguide antennas.

After so many years I tried to recreate this antenna with the dielectric lens....

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

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 4G LTE MiMO 2x2 Tsar-Pushka VARIUS antenna differs significantly from conventional ribbed-rod "pushka" antennas in its wider frequency band. While conventional antenna guns can only be designed and manufactured for a single frequency band, the Tsar Cannon Varius antenna model works perfectly in the 800 MHz band from 1700 MHz to 2550 MHz. The Tsar Cannon antenna can be used on the following bands: Band 1 (1800 MHz) Band 3 (2100 MHz) Band 40 (2300 MHz) Wi-Fi 2.4 (2400-2500 MHz) The antenna has excellent cross-polarization isolation, which allows the MiMO 2x2 technology to operate as stably as possible. Maximum antenna gain of 11-14 dBi The Tsar Cannon antenna has a pronounced radiation pattern. The antenna can also be used in the 2500-2700 MHz band (Band 7, Band 38), but the gain will be low and the SWR will be high. We recommend using this antenna in these bands only in extreme cases when there are no other options available.

,,,2.1---2.5 GHz, is the frequency range quite good...???

,,,does this suit you...??

I don't know if this can help you.....

Is a Russian patch-antenna for its positioning in the focus of a parabola offset... Antenna is broadband (2.3-2.7GHz) Bester Antenna on the offset dish It has a elliptical polarization antenna.

If I remember correctly, I tried something like this... but I'll try this square bester too, inside of beercan...

,,,there... bester.stl

Clanon, maybe you can optimize this.... bester comercial.cst

I wonder if the antenna elements have concentric copper circles on PCB...???

Yes, but it seems that many people still buy it....

This page details the construction of a biquad antenna. The biquad antenna is easy to build, and provides a reliable 11dBi gain, with a fairly wide beamwidth. an antenna geometry of ideal biquad...

Okay, but what's interesting is that this antenna has elements made of PCB....!!!

,,,,hi buddy...!!!! It's pretty good, if you have it, try it....!!!

,,,maybe USB Adapter can increase the gain...!!!???

Because this site is not completed in real operation, it is recommended to replace the current Theme2(Default) with Default, as you can see in the picture below... Default theme it looks like this...

This panel rectangular 4+4 patch antenna can also give you better performance because of its high peak gain of 19dBi. {recommended for drone tracking antennas} overall dimensions=120x200x10mm The antenna patches are suspended on a polystyrene dielectric...

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...
