This letter presents a novel tri-band filter design using an ultraminiaturized substrate-integrated
waveguide (SIW) cavity operated at evanescent mode. Two miniaturized SIW cavities in …

The contribution of this work is to propose novel balanced bandpass filters (BPFs) using the
half-mode substrate integrated waveguide (HMSIW) and its size-reduced form, a folded …

A novel design of a circularly polarized annular-ring slot antenna is discussed. The circular
polarization is attained through a newly proposed double-bent microstripline that feeds the …

The contribution of this letter is to propose an evanescent-mode ultraminiaturized substrate
integrated waveguide (SIW) cavity resonator and its application in bandpass filter (BPF) …

The contribution of this work is to propose an ultra‐miniaturised substrate‐integrated coaxial
cavity (SICC) and its applications in bandpass filter (BPF) design. The proposed SICC …

This letter presents a novel phase inverter (PI) design and its application in a magic-T based
on substrate-integrated coaxial lines (SICLs). The novel SICL PI and its derivative magic-T …

The contribution of this work is to propose a half-mode substrate integrated coaxial resonator
(HMSICR) and its application in bandpass filter (BPF) design. The proposed HMSICR is …

In this paper, two irises are orthogonally connected to a slot‐ring antenna via short‐length
slits with each of the slits loaded by a pin diode. This antenna can be switched back and forth …

The contribution of this work is to propose miniaturized trisection bandpass filters (BPFs)
using size-reduced substrate integrated coaxial resonators (SICRs). The applied SICRs are …

An arbitrarily shaped microstrip patch antenna excited through an arbitrarily shaped aperture
in the mouth of a rectangular waveguide is investigated theoretically and experimentally. …
