Rectangular Horn Antenna

Rectangular horn antenna is one of the simplest and most widely used antennas. Horns have been used for more than a hundred years, and today are used in radio astronomy, satellite communications, in communication dishes as feeders, in measurements, etc. The main characteristic of the rectangular horn antenna presented here is its approximately 20 dB gain. Horn antenna can be considered as an especially designed waveguide extension. The most important parameters for operation of this antenna are shown ... read more

Loaded Circular Horn Antenna

Main characteristics of a horn antenna filled with dielectric is side lobe suppression, decreasing beamwidth and thus increasing gain in relation to antenna without dielectric. In WIPL-D Pro, this horn antenna can be modeled in a very simple way, by using several parameterized geometrical objects as building blocks. One can use the Symmetry feature in both electric and magnetic plane, so only half or quarter of given antenna needs to be modeled. Antenna is considered to be surrounded by vacuum, i.e. it is located in free-space ... read more
