The antenna works at X-band, and it is comprised of sixteen alternately arranged broad-wall and ridgewall slotted array. A series of slots with different parameters are inserted in the broad-wall or the ridge-wall of a single ridge waveguide. They can radiate horizontally polarized and vertically polarized electromagnetic wave respectively. Because single ridge waveguide is relatively small in size compared to rectangular waveguide at the same operating frequency, the spacing of array element is reduced and the scanning angle of array is greatly increased. Simulated results show that the maximum scan angle of the proposed antenna is 30°. Furthermore, with Taylor distribution used for weighting, its side lobe level is less than -27 dB in another dimension.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115885193","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}

With TE11 as the main mode, the integral power calculated according to the pattern of conical horn antenna for different power ratios of TM01 (0, 2%, 5%, 10%, 20%) is simulated and analyzed in the paper. The results show that with the increase of TM01 power ratio, the gain decreases and the 3dB lobe width increases. The H pattern is still symmetric with respect to the antenna spindle, however, the E pattern whose maximum radiation direction gradually deviates from the main axis no longer presents symmetric distribution. If E pattern and H pattern is adopted separately, the integral power will be greater than or less than 100% of real radiation power when the symmetry of E pattern and H pattern is poor. In the presence of hybrid modes, the difference between the results of theoretical integration and the results of bilateral integration for asymmetric pattern can be reduced.
