In this paper, a new idea is proposed in order to modify the conventional Wilkinson power
dividers for size reduction. The proposed structures contain Step Impedance Transmission …

A novel backward microstrip coupled-line coupler which has been designed based on the
metamaterial and composite right/left handed (CRLH) transmission line (TL) concepts is …

We present a design of dual-band bandpass filter (BPF) using a ring-like stepped-
impedance-resonator (SIR) and embedded coupled open stubs for application to a wireless …

A new tri-band bandpass filter (BPF) designed based on two direct-coupled stepped
impedance resonators (SIRs) with open stubs is proposed. Firstly, the resonant …

A novel kind of compact composite right/left-handed (CRLH) transmission line (TL) is
proposed in this paper. The unit cell of this structure consists of a novel metal-insulator-metal …

A switchable bandpass filter using E-type resonators with two-state frequency responses is
presented in this paper. The E-type resonator is a short-circuited stub loaded on hairpin …

In this paper, a new explanation on the radiation mechanisms of slow and fast traveling
waves is presented. The effective radiation sections that give rise to the far-field radiation of …

This letter presents a novel recursive active filter topology that provides dual-band
performance, with independent tuning capability in both bands. The dual-band operation is …

A compact first-negative-order resonance-based small loop antenna is proposed which
consists of two unit cells of composite right-left hand transmission line (CRLH TL). By folding …

We study the propagation of waves in waveguide gratings with a double negative cover. The
waveguide grating is considered as a small perturbation to a perfect waveguide and the …
