This article presents a new type of beam-tilted circularly polarized (CP) radial line slot array
(RLSA) antennas. When the conventional beam tilting method is applied to CP-RLSA …

Bull's eye antennas exhibit remarkable directivity considering their low profile, albeit
accompanied by high sidelobes. This undesirable radiation characteristic is tackled here by …

This letter demonstrates that an inexpensive, easy-to-deploy, and portable 3-D-printed all-
dielectric corner-like Bragg reflector can boost antenna gain. Notably, the concept shown …

This paper presents a comparison of two gain-enhancement techniques and the
development of an extremely high-gain slotted waveguide antenna array (SWAA) aiming at …

This article introduces a compact linearly polarized (LP) radial line slot array antenna
(RSLA) that incorporates a metamaterial of circular ring resonator (CRR) reflector for …

The 5G, 6G of future wireless technology has brought a growing demand for different types
of electrically small or large antennas, which are highly efficient, directive, and provide …

An original design of a multibeam Radial Line Slot Array (RLSA) antenna having two beams
directed to the broadside and two beams directed to the backside is discussed in this …

This paper proposed a radial line slot array antenna (RSLA) design integrated with circular
ring resonator for 5G millimeter-wave applications. It is intended to converge the Federal …

In this paper, a novel linear polarized radial-line slot array antenna working at 30GHz is
proposed. This antenna is composed of two parts, including a metallic slot layer and the …
