RCS reduction and gain enhancement of SRR inspired circularly polarized.

When an antenna receives a signal, it converts that signal into an electric current. To transmit, the process is reversed and the antenna converts the electrical current into a signal. Antenna gain, like amplifier gain, is a measure of how much signal strength is increased. However, antennas do not add energy to the signal from a power supply. MS based broadband, directive slot antenna is realized in. Here AMC is used to reduce back radiation and MS is used as a superstrate. The measured bandwidth is 21.
