摘要: The impedance bandwidth of a high permittivity cylindrical dielectric resonator antenna excited by microstrip line was significantly improved modifying the feed geometry. 10 dB return loss is enhanced from 12 to 26% without much affecting gain and other radiation properties antenna. Good agreement has been observed between predicted measured results.
