Wideband dielectric resonator antenna for C-Band application

Two segment rectangular dielectric resonator antenna of high permittivity (epsivr = 30) ceramic material was design and fabricated at C-band. The antenna was fed with 50Omega microstrip transmission line. In this design, both dielectric resonators (DRs) are separated with metal plate which acting as shorting post. The length of the two DRs is 7.7 mm and 2.2 mm respectively. The optimum distance from the port was chosen at 17.195 mm. The simulated result shows this type of antenna produces wide bandwidth and omni-directional radiation pattern. The simulated gain was 5.5 dB. The result shows the potentiality of this antenna to be used in the wireless communication.
