A novel and compact dual band antenna design for mobile and satellite application is proposed and studied in this paper. The proposed antenna consists of a ground plane having square slot with a rectangular patch at the centre, which is printed on the top of the substrate. A simple 50ohm microstrip line having width 3.08mm is used to excite the parasitic patch from the backside of the substrate. Through some changes like reduction in ground slot, variation in the slots at patch and by impedance matching, gain and bandwidth of the proposed antenna is improved.
