The proposed antenna consists of 50 Q microstrip line feed terminated by balun for good impedance matching, printed multi arms of dipole, and a short strip with finite ground plane. The antenna structures, together with the parasitic elements are designed to achieve broad dual-band extended from 23 GHz to 32 GHz and from 43 GHz to 80 GHz. The antenna has been designed to meet the requirement of ISM band 60 GHz, WLANs, WPANs, W-band, 5th generation cellular (28/38) GHz and 80 GHz automotive radar. Antenna design was first simulated using HFSS ver.14, and obtained results were compared with experimental measurements on a prototype developed of a single printed circuit board.","PeriodicalId":101990,"journal":{"name":"2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128779179","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 filter has passband from 2.9 GHz to 10.6 GHz, the first notched band is designed from 3.5 to 3.9GHz and the second notched band is designed from 6.7 to 7.3GHz, both of which have less than 0.8 dB magnitude of insertion loss and greater than 20dB return loss.

For solving electrically small problems whose rank is constant, its complexity is strictly O(N) in both time and memory. The HSS-representation has a controlled accuracy; and the direct solution of the HSS matrix does not involve further approximation.
