In this paper, a wideband, circularly polarized patch antenna is proposed that leverages the unidirectional resonant modes of a circular patch mounted on top of a grounded dielectric‐ferrite substrate. The proposed antenna is fed via the proximity

We propose a wideband circularly polarized antenna that consists of a metallic patch and some parasitically coupled elements mounted on a grounded dielectric-ferrite substrate. The metallic patch is fed by a proximity-coupled feed line placed between

In this letter, a new dual-band bandpass filter with multispurious suppression is proposed using novel stepped-impedance resonators (SIRs). The proposed resonator is composed of a SIR with embedded bandstop structure. A third-order filter is designed

In this paper, a new compact dual-band bandpass filter with multi-Spurious Suppression is proposed, which is composed of stub-loaded step impedance resonators. The stub-loaded SIRs are used to decrease the dimensions of the resonators and increase un
