High Frequency Wideband Vhf And Uhf Horn Antenna High Rigidity
Sinoscite technology and products cover a frequency range of 0.2 GHz to 220 GHz, mainly including various microwave and millimeter waves, terahertz filters, multiplexers, directional couplers, waveguide calibration components, etc. In addition, if the customer's antenna coverage angle is strictly required, we can also use this antenna to meet the demand. Our antennas are excellent in electrical performance and have been supplied to many schools and research institutes as standard gain 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 have a wide impedance bandwidth, implying that the input impedance is slowly varying over a wide frequency range (which also implies low values for S11 or VSWR). The bandwidth for practical horn antennas can be on the order of 20:1 (for instance, operating from 1 GHz-20 GHz), with a 10:1 bandwidth not being uncommon.
The gain of horn antennas often increases (and the beamwidth decreases) as the frequency of operation is increased. This is because the size of the horn aperture is always measured in wavelengths; at higher frequencies the horn antenna is "electrically larger"; this is because a higher frequency has a smaller wavelength. Since the horn antenna has a fixed physical size (say a square aperture of 20 cm across, for instance), the aperture is more wavelengths across at higher frequencies. And, a recurring theme in antenna theory is that larger antennas (in terms of wavelengths in size) have higher directivities.
Horn antennas have very little loss, so the directivity of a horn is roughly equal to its gain.
Horn antennas are somewhat intuitive and relatively simple to manufacture. In addition, acoustic horn antennas are also used in transmitting sound waves (for example, with a megaphone). Horn antennas are also often used to feed a dish antenna, or as a "standard gain" antenna in measurements.
