G. Drossos et al., EXPERIMENTAL INVESTIGATION OF A CYLINDRICAL DIELECTRIC RESONATOR ANTENNA AT 77 K, Microwave and optical technology letters, 14(1), 1997, pp. 62-64
DRAs offer good radiation characteristics at room temperature, but the
ir performance at low temperatures has not been studied yet. A cylindr
ical DRA is experimentally investigated at room temperature (300 K) an
d in liquid nitrogen (77 K). The experimental results indicate a sligh
tly improved performance at 77 K, denoting the suitability of DRAs for
satellite antenna applications. (C) 1997 John Wiley & Sons, Inc.
