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 A new satellite‐tracking method is proposed for a directional antenna installed on a car for L‐band land‐mobile satellite communication. This method uses both a fiber optic gyroscope (FOG) and a magnetic compass (MC) with an open‐loop control algorithm, which com pensates for the disadv
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
## Abstract An economical electronically‐scanned patch antenna array with quasi‐hemispheric coverage is under design in our laboratory for Inmarsat satellite communications. This paper reports the CAD simulation and test results of a simple‐structured, electromagnetically‐coupled patch antenna with
The Communications and Broadcasting Engineering Test Satellite (COMETS) was developed to evaluate Ka-band (31/21 GHz) and millimetre-wave (47/44 GHz) advanced mobile satellite communications systems, 21 GHz advanced satellite broadcasting systems, and S-band and Ka-band inter-orbit satellite communi
