Hybrid resonators along with dielectric shaping and impedance matching methods are served to effectively excite a family of monopole-like radiation inside the dielectric. In the second antenna, a composite configuration is also applied to improve the matching at higher parts of the frequency bandwidth. Clearly, simulation results show an effective ultra-wide bandwidth of more than 10 GHz ranging from 1.8 GHz to 12 GHz. Furthermore, the radiation pattern of the proposed antenna is nearly omni-directional over the operating frequency bandwidth.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124262087","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}

Due to these features they are widely used in various applications. It is well known that a slot antenna positioned perpendicular to the microstrip feed line can be modeled by a series impedance whose value is determined by the offset (x) and the length of the slot (l). For the characterization of the slot impedance in terms of these two parameters two different approaches can be found in literature [1,2]. In the classical paper of Pozar [1], the full-wave analysis of the slot antenna is performed by the spectral domain Method of Moments (MoM) technique and the impedance value is obtained via reciprocity theorem. A similar analysis technique is also applied in [3] and the variation of slot impedance with the thickness and permittivity of the dielectric substrate is studied. On the other hand, in [2] the slot characterization is done experimentally by utilizing the TRL calibration technique and an 8 element linear array is designed through the use of the transmission line theory with each slot modeled as a series impedance.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114368810","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 electromagnetic energy should reflect back when it hits the reflect-array surface. It has become very popular due to the advancement of printed antennas because of low surface profile, small mass and low cost [2, 3]. We have been studying microstrip rings as the cell element to obtain a reflect-array. When there is an aperture on the ground plane, the distance of the rings can be adjusted to obtain appropriate phases so that the electromagnetic energy can propagate through the ground plane or reflect back. The aperture size is another important parameter to obtain the reflection. When the aperture on the ground plane is partially shorted using a micrsotrip, the length of the aperture is essentially reduced, and the reflection from the structure can be achieved. In this paper, simulation results of the unit cell of a reflect-array are discussed, which is based on square rings with an aperture on the ground plane. The effects of the aperture size and the use of shorting strips are presented. The cell is in an infinite array environment. Simulations were carried out in Ansoft HFSS, version 12.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114802674","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}

By varying the relative phase difference and magnitude between SWL elements, the excited SW field distribution on the guiding surface can be steered and controlled. Simulations and measurements of a single SWL element are provided along with simulations of the proposed array. If metallic gratings or strips, or additional dielectric layers are placed on top of the GDS, the bound SWs can be transformed into radiated leaky-waves (LWs) and directive beam patterns can be generated in the far field. Examples are provided illustrating that broadside beam steering and circular polarization can be achieved at a single frequency.
