|Title:||A SIW-based Wideband Circularly Polarized 4×4 Patch Array Antenna in 45 GHz Band||Authors:||Li, Chenfeng; Liu, Pengfei; Zhu, Xiao-Wei; Zhu, Anding||Permanent link:||http://hdl.handle.net/10197/12073||Date:||22-Aug-2019||Online since:||2021-03-31T10:58:56Z||Abstract:||In this paper, a substrate integrated waveguide (SIW)-based wideband circularly polarized (CP) 4×4 patch array antenna operating in 45 GHz band is proposed. Firstly, a series-fed 1×4 patch subarray is designed. Sequential rotation (SR) feeding technology is adopted to extend axial-ratio (AR) bandwidth. Then, a 4×4 patch array antenna using four 1×4 patch subarrays is presented. The anti-phase feeding network is used to obtain stable CP radiation patterns among wide frequency band. The proposed antenna was fabricated and measured. -10-dB|S11| bandwidth of 27.6% (36.4-51.2 GHz), 3-dB AR bandwidth of 11.6% (41.6-47.6 GHz) and the peak gain of 17.1 dBic are achieved in the vicinity of 45 GHz.||Funding Details:||National Natural Science Foundation of China||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2019 IEEE||Keywords:||Substrate integrated waveguide (SDI); Circular polarization; 45 GHz; Sequential rotation||DOI:||10.1109/UCMMT47867.2019.9008312||Other versions:||http://imws2014.eecs.qmul.ac.uk/||Language:||en||Status of Item:||Peer reviewed||Is part of:||Proceedings of 2019 12th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)||Conference Details:||The 2019 12th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT), London, United Kingdom, 20-22 August 2019||ISBN:||9781728129914||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
