Description
Summary:	This paper presents a compact left hand circularly polarized patch antennas with multiple asymmetrical v shaped slits and cross slots for X and Ku band frequency range. The simulated patch antennas are resonating in between 10.8 GHz to 12.25 GHz. The varying lengths, widths and circumference of the slots/slits and also the position of them on the patch will be crucial in achieving circular polarization. Three different antennas with V shaped slits at the corners, V slits along with circular slots and cross slots etched on the patch antenna are presented. The obtained average simulated gain of the patch is about 7 dBi. The LHCP antenna is having an impedance bandwidth of about 16% and axial bandwidth of 3.1%. These proposed antennas are good for space communications, earth exploration and DBS applications.
