In this paper, Gap filler antenna for satellite DMB(Digital Multimedia Broadcasting) is designed. The antenna consists of radiation patch, crossed aperture and feed network. The patch is square to generate circular polarization. The feed network drives- the crossed slots with equal amplitude and a 90° phase shift and provides a matched input to the antenna. The designed antenna shows gain of 6.6 dBi and axial ratio of within 4 dB over 2.605-2.655 GHz.
