A novel filtering method based on the metasurface antenna (MSA) with radiation nulls is
proposed without loading extra circuits. Due to the specific multiunit structure of MSA, the …

Filtering antennas or filtennas realize both antennas and filter functions in a single structure
with the sole purpose of reducing losses and size in the design of a radio system. This article …

Compact, low-profile, linearly polarized (LP), and circularly polarized (CP) patch-based
filtennas are realized with a custom-designed coupling probe. It introduces a deep null at …

A single-layer low-profile circularly polarized (CP) filtering patch antenna is investigated for
wireless local area network (WLAN) applications. The CP antenna mainly consists of a …

A high-gain circularly polarized (CP) filtering stacked patch antenna with independently
controllable radiation nulls is designed without an additional filtering circuit/network in this …

A low-profile omnidirectional dielectric resonator antenna (DRA) with wide-bandwidth and
high-selectivity filtering response is proposed. Initially, the traditional low-profile DRA has no …

A compact wideband filtering patch antenna with high selectivity is presented. The proposed
filtering antenna contains a rectangular patch rounded by a pair of U-shaped patches, and is …

In this article, a polarization reconfigurable concentric circle microstrip antenna with
simultaneous frequency agility has presented. The frequency agility and polarization …

This article presents a polarization-reconfigurable wideband high-gain antenna based on
liquid metal tuning. The antenna consists of a center-feed circular patch antenna with a C …

Wireless communication has witnessed rapid developments in the last few decades. To
further improve the performance of wireless radio-frequency (RF) systems, emphasis has …
