Jan 4, 2021 · To define a horn antenna, we should know the proper definition of the antenna. According to IEEE standard definitions of antennas, “An antenna is a means for radiating or receiving radio waves”.
Normally, the horn antennas are used in the form of a feed horn for large antennas like a parabolic antenna and directive antenna. Let us discuss a horn antenna in detail with its working, design features, and benefits of using it.

It is a directional antenna which is used to increase directivityIt helps in improving impedance matching because the waveguide mostly has impedance of about 50Ω while the impedance of the free space is 377Ω. In order to match out the impedance so as to reduce power loss, a flaring is used to kind of concentrate the electromagnetic waves.It is used...
The figure above shows a cross section diagram of horn antenna along the E-plane which can be used to analyze its parameters such as the flaring angle theta, the axial length L, the height of flaring or aperture H.
It be categorized as 1. Sectoral horn antenna 2. Pyramidal horn antenna 3. Conical horn antenna and Bi-conical horn antenna
In addition to the uses of horn antenna discussed above, here are some of its other applications 1. It is used for microwave application 2. It is used in satellite communication 3. It is used as the active element (feed horn) in a dish antenna to receive the reflected wave. 4. Horn antenna works in the Ultra High Frequency (UHF) 300Mhz and Super Hi...
1 Rectangular Horn Antennas. Horn antennas are popular in the microwave bands (above 1 GHz). Horns provide high gain, low VSWR (with waveguide feeds), relatively wide bandwidth, and they are not difficult to make. There are three basic types of rectangular horns. [Balanis]

Horn Antenna. Introduction to Horn Antennas. Horn antennas are very popular at UHF (300 MHz-3 GHz) and higher frequencies (I've heard of horn antennas operating as high as 140 GHz). Horn antennas often have a directional radiation pattern with a high antenna gain , which can range up to 25 dB in some cases, with 10-20 dB being typical.
Horn antennas are directional, high-gain and low-loss antennas used since the 1890s. They have various characteristics such as flare angle, aperture efficiency and frequency capabilities which influence performance.
Mar 30, 2023 · Horn antennas are a type of directional antenna that are used to transmit and receive radio waves. They consist of a flared metal plate or tube, and are highly efficient with...
