Abstract:
very-high-permittivity (e, = 100) multiband dielectrice>
e resonator antenna is presented. The compact antenna, excited by a
m:'crostrip line, resonates at two frequencies centered around the 1.9-
GHz and 2.4-GHz bands with identical polarization . The behavior of the
antenna at different positions along the feed line is studied and optimized.
Multiple resonances with the same polarization and broad radioticn
patterns suggest the suitability of the antenna for multiband wireless
application

Abstract:
rectangular low-density, high-permittivity dielectric
resona or antenna (DRA) excited by T-shaped microstrip feed offering a
2:1 VSWR bandwidth of -22% at 2.975 GHz is reported. The design
methoaology and experimental results of the antenna are discussed. The
excellent gain and radiation performance of the proposed antenna
project: it as a potential candidate for telecommunication applications
