RADIATION PATTERN MEASURMENT SYSTM USING USB INTERFACING
Main Article Content
Abstract
ny communication system an antenna plays an important role. It is an interfacebetween the guided wave and the free space wave. The antenna is a device which interfaces a circuit and space. To use any antenna in a communication system either as transmitting or receiving, its gain pattern to be known. The gain and of an antenna is an actual quantity which is less than the directivity D.A. mismatch in feeding the antenna can also reduce the gain. The gain pattern gives the information related to gain and beam width an antenna. We proposed the computerized VHF/UHF antenna gain pattern measurement system.
