Use of the Differential Dielectric Resonator Antenna for an Independently Controllable Dual-Band Filter

In this letter, a novel concept for the dielectric resonator functioning as a differential antenna and as an independently controllable dual-band filter simultaneously is proposed for the first time. The multifunctional design takes full advantage of the virtual and reflection grounds of the differential dielectric resonator antenna (DDRA). The antenna and filter functions share a single module an...
