Compact circular patch with meander line monopole antenna for X-band applications

A compact circular patch with slotted meander line (CPSM) microstrip monopole antenna is proposed for X-band applications. Symmetrical circular patches with rectangular slots on either side of monopole feed line to enhance the bandwidth and gain. Impedance bandwidth of proposed antenna is 11.5 %. The operational frequency range of CPSM antenna is 10.48 GHz to 11.74 GHz (1.26GHz bandwidth). The size of the designed CPSM antenna is 75×75mm

. The VSWR is < 2 for the entire band of frequencies.
