In recent years, with the rapid development of integrated circuits, the filtering antenna (FA)
circuit of the substrate integrated waveguide (SIW) has attracted widespread attention in …

In this letter, a novel compact filtering patch antenna with high suppression level is
proposed. The fork-shaped feedline and the two half-wavelength strips are used to excite …

The increasing demand for efficient data transmission and reception, coupled with high-
speed data requirements, is set to drive the extensive global deployment of emerging …

This letter presents a wideband circularly polarized (CP) antenna with filtering radiation
response based on a slot-patch structure. The proposed CP filtering antenna is composed of …

A novel millimeter-wave 2× 2 substrate integrated waveguide (SIW) cavity-backed patch
subarray with a simplified feeding structure is presented. Two higher order SIW cavity modes …

This letter presents a wideband sequential-rotated (SR) circularly polarized (CP) 2× 2
filtenna array with multiple radiation nulls for high out-of-band rejection level. A pair of arc …

This article presents a general design method for the aperture-coupled linearly polarized
(LP) and circularly polarized (CP) reconfigurable antennas. A novel double-ring-slot …

A high-gain reflectionless circularly polarized (CP) filtering antenna is proposed. A
quadrature hybrid coupler (QHC) is cascaded with two identical, mutually isolated, and …

An integrated low-profile dual-band filtering antenna is proposed in this letter. By resha**
a square substrate integrated waveguide (SIW) cavity, diagonal TE 102 and TE 201 modes …

The fifth generation (5G) mobile communication systems employ technologies such as
massive MIMO, millimeter-wave (mmWave), and ultra-dense networks to support higher …
