Summary:
Rather than reflector antennas, the development of waveguide slot antennas [1], which have advantages of low profile and low transmission loss, are also undergoing for their application in high gain (39dB ~) and high frequency (26GHz ~) Fixed Wireless Access (FWA) systems. The radiation pattern envelope (RPE) generally with suppressed sidelobes is an important design parameter when introducing the antennas into a practical communication or radar system. For example, the European Telecommunications Standards Institute (ETSI) [2] and Japan Ministry of Internal Affairs and Communications [3] have determined the specifications of wireless system in certain frequency band. In this paper, the synthesis of radiation pattern for a 32×64-element waveguide slot array is studied based on the Woodward-Lawson method [4]. Moreover, the Modified Edge Representation (MER) method [5][6] is also introduced when investigating the effects of a finite ground plane on the radiation especially in the back side of antennas.
