Loop elements placed on the dipole aperture provide a dual-band operation without deteriorating gain and pattern characteristics. In addition, a new balun-feed configuration with a tapered microstrip transition backed by a triangular ground plane is also introduced to eliminate the inherent unbalanced current excitation of a coaxial feeding element. A corporate-feed structure is also employed for the excitation of the 2×2 LLPD array. It is numerically demonstrated that the proposed array offers a minimum 15% impedance bandwidth and a realized gain of at least 10 dB at the designated frequency bands. The full-wave analyses of the LLPD designs are carried out using CST Microwave Studio.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130655310","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}

For dual-mode resonance, the ring resonator is directly connected with nonorthogonal feed-line via coupling capacitors. And two different short-circuited stubs are simultaneously placed at two corners along the symmetric plane of the ring resonator. These two stubs make it possible to provide a transmission zero near the lower second passband edge. The proposed dual-band filter was fabricated. As a result of measurement, it exhibits center frequency (fractional bandwidth) of 2.3 (15.8%) and 4.9 GHz (25.7%) with insertion loss of 0.74 dB and 0.56 dB, respectively. So, the proposed filter has attractive features of low insertion loss and wide bandwidth compared to other dual-band filters. Thus, it should be well suited not only for wideband WLAN applications but also for any other communication systems.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122457271","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 well-known shooting-bouncing ray (SBR) method [1, 2] combined with physical theory of diffraction (PTD) technique [3, 4] is employed to estimate the far-field scattered electric field from the target as a whole. The PTD method used in this paper to calculate a diffraction contribution for each ray hits the platform's surface vicinity of an edge. To show the effect of leading and trailing edge diffractions on 2-D ISAR images, first, a wing like test model and then a large complex platform are considered. It is demonstrated that the diffraction phenomena from the leading or the trailing edge becomes more distinctive on 2-D ISAR images if an appropriate polarization and illumination condition for the related edge is provided.","PeriodicalId":145274,"journal":{"name":"2010 10th Mediterranean Microwave Symposium","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121126518","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}
