Dielectric resonator antenna array at 2.4 GHz

Four by four (4 times 4) array of DRA with transmission line feed technique has been designed simulated and compared in this paper. It shows that the return loss between the measurement and simulation are within the frequency band that has been designed. The slightly shifted frequency is due to the FR4 board that has epsiv

varies from 4.0 to 4.8. The return loss at - 10 dB shows a good impedance matching occur between simulation and measurement. The gain obtained from measurement is 10 dB more compared to monopole antenna operating at the same frequency.
