In this paper, we proposed and fabricated the single feed microstrip patch antenna with slot for S-DMB(Satellite-Digital Multimedia Broadcasting). In order to improve of frequency properties, patch size, feed length, and slot size were investigated by HFSS simulation program. The manufactured single feed microstrip patch antenna with slot showed that the measured center frequency, the minimum return loss and -10dB bandwidth were 2.64GHz, -34.67dB and 180MHz, respectively.
