英文摘要 | A technique for tuning the resonant frequency of a microstripline feed rectangular dielectric resonator (DR) antenna using a parasitic disk on top of the DR with an adjustable air gap is presented. By varying the air gap height, the DR antenna resonant frequency will also vary but has similar radiation patterns. |
