Ku-band
The Ku-band satellites are often placed as little as two degrees apart from each other in the Earth's orbit. This increases the chances of adjacent satellite interference. The Ka-band satellites are placed further apart from each other, and therefore, the chances of antennas transmitting to non-targeted satellites and interference between ...In this letter, a high-gain, high-efficiency, and high-isolation Ku/Ka-band dual-frequency shared-aperture antenna array using a frequency selective surface (FSS) is investigated.
