Due to the rapid development of technology in communication, there is an increasing need for antenna systems with good performance. As receiving and transmitting radio wave equipment, the antenna is a critical component of the whole system. The reflective surface antenna(parabolic dish antenna) has unique advantages, and it\u2019s widely used in communication, radar, radio astronomy, etc. As the feed source or direct radiator of the whole reflector antenna, the horn antenna directly affects the performance of the entire reflector system.<\/p>\n\n\n\n

When choosing a horn antenna, you need to focus on a couple of parameters based on your application. It\u2019s included but not limited to frequency ranges, gain, polarization as well as the half-power beamwidth, etc. <\/p>\n\n\n\n

Currently, most commercial fixed wireless services use C-band. With the increasing variety of communication services, Ku\/Ka-band is gaining more and more attention after being fully developed by reducing the track spacing and adopting orthogonal polarization multiplexing and spatial multiplexing. In terms of bandwidth, Ku\/Ka-band is much larger than C-band, especially Ka-band, so it is the primary band for the new generation of high-capacity communication systems.<\/p>\n\n\n\n

Late in World War II, Germany first used a radar that operated at a wavelength of only 1.5 cm, called K-band radar. K is the initial of the German word Kurz (short). Unfortunately, the Germans\u2019 frequency happened to be very easily absorbed by water vapor, making it unusable in foggy or rainy weather. Radars after World War II usually used Ku (K-under) band or Ka (K-above) band to avoid the water vapor absorption peak in the K band. The specific band division is shown in the table below:<\/p>\n\n\n\n
