Dielectric Resonator Antenna for Wide Millimeter-Wave band

摘要

A rectangular dielectric resonator antenna (DRA) is excited by properly combine two higher-order modes, TE113 and TE115 to provide a wide 10-dB impedance bandwidth of about 25% in millimeter wave band. The variation of antenna gain is less than 1.5 dB across impedance passband (|S11|<-10dB).
