Broad bandwidth is realized by using a planar out-of-phase power divider with ultra-wideband performance and periodic dipole elements. The device uses two substrates with a common ground plane. A coupling between two microstrip lines on the top and bottom substrate layers through a slot in the common ground plane , and a transition from two microstrip lines to a parallel stripline are used to achieve an ultra-wideband operation. The gain enhancement is achieved by loading split-ring resonator (SRR) structure in the endfire direction. The effect of the SRR-shape unit structure on the gain enhancement is investigated. Both SRR-loaded antenna and unloaded one are fabricated to verify the predications. The measurements show that SRR-loaded antenna presents gain of about 7dB-10dB in the whole working band (3.5GHz-11GHz) ,which is about 2dB-4.5dB more than the unloaded one. This antenna can be used in wireless communication systems for its advantages of the broad bandwidth and high gain.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133339546","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}

There is no need to introduce any blocking capacities and the bias network is very simple. The two I-shaped stubs and switches are the key elements to the operating bands of the proposed antenna.

A super-element based on four basic structures are developed to realize the active control and the polarization-insensitivity simultaneously. Compared to the switchable designs previously reported, the proposed structure has the advantage of possessing multiple real-time and switchable operating states (i.e. dual-poalrizaed absorption, dual-polarized reflection, TE absorption/TM reflection and TE reflection/TM absorption), and meanwhile, attaining a much wider switchable bandwidth.","PeriodicalId":342849,"journal":{"name":"2019 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116336852","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}
