This article provides a comprehensive review of recent applications of characteristic mode
analysis (CMA) to innovative antenna element designs, including multiport, circularly …

In this letter, a multiple-input and multiple-output (MIMO) antenna with ultra-wideband
performance for 5G smartphones is investigated. Firstly, a compact antenna-element with a …

In this paper, methods for improving frequency selectivity in filter antennas by employing
controllable radiation nulls (RN) are reviewed. Radiation nulls in the Gain graph help in …

Wideband slot-coupled microstrip antenna (SCMSA) is a distinctive electromagnetic wave
radiator in recent years with wide bandwidth and low profile. In such a wide frequency …

A substrate-integrated waveguide (SIW) antenna is an implementation of a waveguide
antenna in a microstrip antenna. The microstrip antenna, as a low-profile antenna, suffers …

A low-profile, wideband, and high-gain antenna array, based on a novel double-H-shaped
slot microstrip patch radiating element and robust against high temperature variations, is …

A Ka-band CPW-Slot-Couple (CSC) fed microstrip antenna with enhanced bandwidth and
gain is presented in this paper. To simplify the feed network, the matching slots are designed …

In this paper, a compact broadband planar inverted-F antenna (PIFA) with dual-resonant
modes (TM1/2, 2 and TM3/2, 0) is proposed for 5G applications. By loading a pair of …

A dual-polarization self-duplex antenna is proposed. When port 1 is excited, two half-modes
(HM) resonances having similar radiation performance are produced by a slotted HM …

In this paper, a microstrip patch antenna fed by a waveguide using an end-wall iris through
ground plane has been modelled. The iris feed technique was proposed to overcome the …
