In this paper, a linearly polarised radial line slot array antenna (LP-RLSA) is presented for satellite communication. The antenna makes use of reflection cancelling slots to improve impedance matching. The antenna has highly directive radiation with a peak directivity of 37 dBi at 12.3 GHz. At this directivity, the antenna has demonstrated a very lower side lobe level (SLL) of -23.1 dB and radiation efficiency greater than 96%. The designed LP-RLSA antenna has successfully overcame the limitation of poor return loss through reflection cancelling slots.
