design of RLSA, that is, the suppression of reflection in the antenna and the slot coupling control. Excellent performances, the antenna gain of 36.3 dBi and the efficiency of 76% at 12GHz, are realized for a DBS receiving model antenna.
A Radial Line Slot Antenna (RLSA) is a novel planar array. This paper discusses the key design of RLSA, that is, the suppression of reflection in the antenna and the slot coupling control. Excellent performances, the antenna gain of 36.3dBi and the efficiency of 76% at 12GHz, are realized for a DBS receiving model antenna.
