Abstract :
The direct broadcast satellite radio (DBSR) program is a joint effort between NASA and the United States Information Agency/Voice of America (USIA/VOA). DBSR will offer audio signals with various levels of sound quality (AM, FM, and CD) to reach a variety of radio receiver types (fixed, portable, and mobile) in various environments (indoor/outdoor, rural urban, and suburban). JPL has successfully conducted two reception experiments and demonstrations via a NASA tracking data relay satellite (TDRS) at 62/spl deg/ West longitude with the sound signal send from White Sands, New Mexico. These live demonstrations were conducted at Pasadena, California and at Buenos Aires, Argentina in June and September, respectively. This paper describes the low cost antennas developed at JPL for the two demonstrations. They are the drooping dipole and the TM/sub 21/ mode circular patch antennas for mobile platforms as well as the medium gain antenna for indoor environments.<>
