I tried to do a simulation for this simple antenna,,,,

,,,400 mm length...for 2100MHz to 2600 MHz

Two examples of how it's done...

As you can see...!!!

I think this connector is used on the Tzar Antenna.... N-P245 mufa.cst

length=1370mm

LOOOONG TZAR YAGI...950 mm

,,, a rim around the reflector,it is not of major importance,so it may be missing...!!!

I think such an antenna with such characteristics, besides the fact that it is very long, is even more difficult to obtain. Anyway ,I will try to satisfy your request...!!!

,,,,prda, your antenna looks like this... ,,,your antenna... ,,,and patch antenna 5 GHz ,10 dBi...

I tried to do a simulation for this antenna and it resulted in some miniature dimensions....!!! ,,,and for the 5.8 GHz frequency...

If you solder the shield of the coaxial cable to the ground, it is not recommended.

The dielectric constant of styrofoam (expanded polystyrene) is approximately 1.02–1.04. This low value is due to its low density, which consists of air bubbles (with a dielectric constant close to 1) and the polystyrene material itself. The dielectric constant of solid polystyrene resin, without the air pockets, is higher, ranging from 2.4 to 2.6. For expanded polystyrene (styrofoam): The dielectric constant is approximately 1.02–1.04, which is a very low value due to the high volume of air in the foam. For solid polystyrene resin: The dielectric constant is higher, ranging from 2.4 to 2.6. Factors influencing the value: The dielectric constant is influenced by factors such as density, moisture, temperature, and frequency. Frequency dependence: While the dielectric constant of solid polystyrene is relatively flat up to 1 GHz, the value for the foam is measured in specific ranges, like 100-400 MHz.

This is harder to build...

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