Zn. Chen et al., EFFECT OF PARASITIC DISK ON A COAXIAL PROBE-FED DIELECTRIC RESONATOR ANTENNA, Microwave and optical technology letters, 15(3), 1997, pp. 166-168
The characteristics of the dielectric resonator antenna top loaded by
a circular conducting disk with different diameters is studied experim
entally. It is found that antenna parameters such as the resonant freq
uency, the input impedance, and the far-field radiation pattern, are a
ffected tremendously by the conducting disk Therefore one can tune the
antenna parameters by varying the disk size. (C) 1997 John Wiley & So
