The antenna consists of three parts: The first part is the upper linearly polarized grid (LPG), which can transmit one linearly polarized wave through its orthogonal linearly polarized wave at the same time. The second part is the lower dual-polarized OAM reflectarray, which can generate high gain OAM vortex electromagnetic wave. It plays the role of polarization torsion on the linearly polarized wave emitted by the feed-source at the same time, so as to realize the folding performance of the ref-lectarray, which reduces the longitudinal profile of the reflectarray antenna.

Microstrip comb array is improved according to the transmission characteristics of microstrip grid array antenna, which removes the transmission long side without changing its function. In this paper, a 24 GHz vehicle mounted antenna based on PCB technology is proposed, which has the advantages of high gain, low sidelobe and narrow beam. Firstly, a microstrip comb antenna subarray is designed, and then 10 subarrays are used to form an antenna array. Chebyshev distribution is used to excite each subarray to obtain the low sidelobe level. Finally, the realized gain of the antenna array can reach 28.8 dBi. At the center frequency of 24.125 GHz, the measured sidelobe levels in the E-plane and H-plane are less than − 15 dB.","PeriodicalId":64652,"journal":{"name":"天线学报","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66111268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
