A Proposal of Single-Feed Quad-Polarization Switchable Patch Array Antenna Using Slot-Line Based Phase Shifters

Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a single-feed quad-polarization switchable patch array antenna. The antenna comprises a single-layer structure including four patch antennas and slot-line-based phase shifters. Two phase shifters control the horizontal feed with 0-deg. or 180-deg. phase shifts, while another two manage the vertical feed with 0-deg. or 90-deg. phase shifts. From the vector analysis of both horizontal and vertical signals phase distribution, the proposed antenna can switch between four polarizations; left-hand circular, right-hand circular, and +/-45-deg. linear polarizations. Simulated results validate the proposed concept, demonstrating its effectiveness without relying on complex RF or DC circuitry. The design ensures simplicity and compactness, making it highly suitable for modern wireless communication systems.
