Printed cross-slot wideband conformai antenna for GPS application

A novel cross-slot printed wideband conformai antenna is proposed for GPS application. The combination of partial ground plane and cross-slot on the patch are used for bandwidth enhancement. The proposed conformal antenna exhibits a fractional bandwidth(for the definition of −10dB) of 79.28% operating from 1091 to 2524 MHz. The radiation pattern exhibits an omnidirectional pattern and gain of the proposed conformal antenna is 2.37 to 5.33dBi within operating frequency range.
