Abstract

Vehicles to everything (V2X) communication includes a variety of types, so wide-angle scanning is integral. For wide-angle scanning, the half power beam width (HPBW) of a single antenna must be wide. Moreover, the gain, low cross-polarization level, and impedance bandwidth are essential factors in high communication performance. In this paper, a wide-angle scanning phased-array system using an arc-shorted half-elliptic patch antenna at 5.8 GHz is presented. The design of both a single antenna and the entire phased-array system are covered, and to verify the design method, the proposed single antenna and phased array system were fabricated. The proposed antenna had 162 ∘ HPBW in the E-plane and 8.63 dBi of peak gain. Its fractional bandwidth was 5%, and the level of cross-polarization was −16.8 dBi. Furthermore, the measured 3 dB scanning angle of the phased-array system was from − 90 ∘ to 90 ∘ . The proposed system has wide-angle scanning. [ABSTRACT FROM AUTHOR]

Abstract

This letter proposes a pattern reconfigurable high gain spherical dielectric resonator antenna (DRA) operating on higher order mode. Two microstrip patches were used to excite $\text{TE}_{301}$ mode in the different direction. A reconfigurable switch network was designed and it has three switching modes for selecting each patch alone or selecting them simultaneously. The proposed antenna can reconfigure its radiation pattern by using a feeding structure, which is consist of two microstrip patches and the reconfigurable switch network. A prototype antenna operating on $\text{TE}_{301}$ mode at 5.8 GHz was fabricated by ceramic material. By experiment, we validated the new concept of pattern reconfigurable spherical DRA.
