We report a new compact square microstrip antenna with surface mounted quasi-planner horn. Horn is made of plastic sheet and painted with silver epoxy. Horn improves gain of patch by 3 dB-4.5 dB without adversely affecting bandwidth which is 2.3%-9%. Horn also improves isolation between array elements by 10 dB. Total thickness of antenna, including horn is only 6.94 mm.
