“…The use of the defected ground structure which when integrated with the patch antenna provided an effective technique in improving the radiation properties of the radiating structure [ 4 ]. The study is further extended in which it is suggested that the use of the stub loaded patch antenna helps in achieving the miniaturization [ 5 ]. The phenomenon of cutting the slots inside a patch antenna is helpful in increasing the bandwidth of the patch antenna at the desired frequency of operation.…”
