Problems arise in providing excitation phases and amplitudes to individual antenna elements for wide-angle scanning by applying spherical array antennas for mobile satellite communications for ships, automobiles, and aircraft. These antennas do not have many antenna elements. Thus, emphasis is on ob

This paper presents the design and de¨elopment of a compact switched-beam array antenna for operation with the Australian mobile satellite communications system. Mobilesat T M . The antenna is formed by eight aperture-coupled microstrip patch elements that are positioned on the side of a truncated c
## Abstract Some beamforming strategies are presented for compact arrays in wireless systems. To rigorously account for mutual coupling, we rely on the exact active element pattern method. By considering a compact and lowβcost array operating in the HiperLAN band, it is shown that the proposed meth
