A closed-form expression for the half-power beamwidth of the array factor of an array antenna is presented. The expression is correct for the ratios of element spacing to wavelength greater than or equal to one quarter. Also, exact equations for determining the half-power beamwidth for main-beam steering are derived. A comparison with an approximate formula for the half-power beamwidth of binomial array antennas is carried out.","PeriodicalId":20579,"journal":{"name":"Progress in Electromagnetics Research Letters","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":"135660057","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}

The effectiveness of the MIMO aerial is demonstrated using envelope correlation coefficient and radiation pattern.

A C-shaped printed antenna with both ends terminated by a small rectangular section is designed as the basic antenna element for a 2 element MIMO antenna of size 0 : 8 (cid:21) (cid:2) 0 : 67 (cid:21) (cid:2) 0 : 04 (cid:21) ( (cid:21) , corresponding to the lowest operating frequency) which operates over the X band with the peak gain of 3 dBi. By introducing a double layered frequency selective surface (FSS) of unit cell dimension 0 : 2 (cid:21) (cid:2) 0 : 2 (cid:21) (cid:2) 0 : 0375 (cid:21) between the two antenna elements as an isolation wall and additionally by placing a 5 (cid:2) 3 array of FSS geometry as a re(cid:13)ector below the antenna, the isolation and gain of the two element MIMO antenna are improved by 37 dB and 3 dBi, respectively. The proposed FSS loaded MIMO antenna provides very high isolation about (cid:0) 51 dB (measured) and a very low envelope correlation coefficient (ECC) of 0.000177282 (simulated) using far (cid:12)eld approach and 0.000000033414 (calculated measured) using scattering ( S ) parameter approach. Further, MIMO parameters like diversity gain (DG), total active re(cid:13)ection coefficient (TARC), mean effective gain (MEG), and channel capacity loss (CCL) have been evaluated. The radiation pattern is unidirectional in nature with a peak gain about 6 dBi. The letter also presents detailed design guidelines for the proposed FSS loaded MIMO antenna along with their veri(cid:12)cations for Ku and K bands. The proposed structure can also be scaled up to a 4 element MIMO antenna.","PeriodicalId":20579,"journal":{"name":"Progress in Electromagnetics Research Letters","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69002844","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}
