Mv. Gryanik et al., MULTIFUNCTIONAL RECEIVING ANTENNAS FOR DIRECT SATELLITE TV BROADCASTING, Telecommunications & radio engineering, 48(5), 1993, pp. 30-36
The trend, observed in recent years, towards the wide introduction of
direct satellite television broadcasting systems has presented designe
rs with the problem of extending the functions of subscriber stations
for collective and individual use, including the possibility of simult
aneously receiving programs from several satellites without having to
redirect the antenna, receiving several frequency bands using a single
antenna, and using portable antenna mirrors. In this paper we conside
r the problems involved in constructing such multifunctional receiving
antennas for direct satellite television broadcasting and also the ba
ricentric method of calculating their parameters.
