Microwave antennas are to be tested necessarily to assure the customer that they perform as per the design specifications. The performance of a microwave antenna can be adjudged by measurements employing open test range, microwave anechoic chamber, Near Field Far Field (NF-FF) techniques and Compact Antenna Test Ranges.Real estate can represent a significant investment for far field ranges, and the only tangible accomplishment of the size is to flatten the amplitude. One of these can serve as a source, offering the possibility of compact range. The primary limitation on field flatness is the...
