In this paper, in order to develop a receiving antenna for the satellite TV, we proposed a flat antenna system using coplanar array of the Twin Delta Loop Antenna (TDLA ) with plane reflector. Several important techniques, for examples, to manufacture the very small TDLA for 12GHz or to design a microstrip balun to feed the balanced TDLA from unbalanced strip line have been introduced to realize the coplanar array of the TDLAs in microwave region like 12GHz. A 256 elements coplanar array of the TDLA are designed and its characteristics are investigated theoretically and experimentally.
