The antenna comes with multiple operation bands that cover the two conventional WLAN bands, which extends from 2400 to 2484 MHz and 5150 to 5925 MHz, as well as the newly added WiFi-6E band that covers the 5925 to 7125 MHz band. The proposed antenna geometry comprises three elements. A printed planar monopole serves as the driven element. A parasitic strip is placed alongside with the monopole. A dual-branch shorted element, which contains an inverted L branch and an inverted C branch, is placed right next to the driving monopole. These structures help excite multiple resonances to form a broad operation band and to improve the matching performance. Simulation results show that the proposed MIMO antenna array has good impedance matching and decoupling performances in the desired WiFi bands.","PeriodicalId":132941,"journal":{"name":"2021 International Symposium on Antennas and Propagation (ISAP)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129889625","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 dual antennas are composed of a differential mode (DM) antenna and a common mode (CM) antenna. They are integrated into the same radiator for size reduction. Their feeding positions are arranged asymmetrically on the radiator, and the high isolation and low envelope correlation coefficients (ECCs) can be obtained without the need of an external decoupled structure. For the first example, the dual antennas are integrated into the rectangular radiator and have a size of 5 x 39 mm2 (about 0.05λ x 0.43λ) for operating at 5G n78 band (3.3-3.8 GHz). The dual antennas show an acceptable isolation of better than 12 dB and their ECC is much less than 0.05 in the operating frequency band. The second example follows the design rule of the first example. The dual antennas are integrated into the T-shaped radiator and show a high isolation of more than 20 dB in the 5G n77 band (3.3-4.2 GHz).

The structure consists of slot antenna designed to operate at Ka band frequency. The effect of introducing slots and two feedline have been extensively studied. The basic structure is designed on a substrate with dielectric constant of 2.2 with a thickness of 0.508mm and loss tangent of 0.0009. The design consists of a SIW antenna fed with a normal microstrip to SIW transition. Multiple slots and different feedlines effects have been studied and analyzed using CST. Signal power reduces at mm wave frequencies as compared to lower frequency bands due to smaller effective aperture size of single element antenna. Therefore, in order to compensate these losses, the mm wave communication systems are required to have high gain antenna. A high gain and efficiency and low losses are major considerations which can be achieved by the proposed design. The proposed antenna geometry has a bandwidth of 1.27GHz with a gain of 8.9 dB at 26GHz and efficiency of 97%.","PeriodicalId":132941,"journal":{"name":"2021 International Symposium on Antennas and Propagation (ISAP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132379497","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}
