Abstract
ABSTRACT A magneto-electric dipole filtering antenna with slots and parasitic elements is proposed and verified in this letter. By utilizing the lower pass-band intrinsic radiation null of the magnetoelectric dipole antenna, a high radiation suppression level is achieved in the low-frequency band. Combining parasitic elements and etching slots on the electrical planes, radiation nulls are introduced in the high-frequency band. The measured |S11|<-10 dB bandwidth of the proposed antenna is 72.6% (1.71–3.66 GHz). The measured results show that the radiation suppression level in the high-frequency band and the low-frequency band is −25.3 dB and −16.8 dB, respectively. Moreover, the measured realized gain is about 7.2 dBi in the operating band.
