A sharp roll-off in RF performance has been achieved by introduction of corrugations in the waveguide structure. Further, short input/output matching networks based on stubs of optimized corrugations has been used for impedance matching. The design method is based on step-shaped band stop elements separated by very short waveguide sections. An 18th order waveguide filter has been designed and realized in a compact length of 130mm. In measurement, low insertion loss of < 0.5dB in passband and sharp roll-off (rejection slope) of > 65 dB per 0.25 GHz has been achieved. This makes the TRF highly suitable for use in Ext. Ku band SATCOM.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116625755","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 unit cell of the proposed absorbing structure consists of metal-backed hollow resin shell filled with water. The proposed structure has been designed and optimized using CST MWS STUDIO, to exhibit 90% absorptivity in frequency band 8–29 GHz (covering complete X-, Ku- and K-band) under normal incidence. The four-fold rotation symmetric unit cell design ensures polarization-insensitivity towards the incident radar signal. The performance of the proposed design is also studied under different oblique incidences and it is observed that the proposed structure holds its absorption characteristics up to 60° of angle of incidence for TM mode and up to 45° of angle of incidence for TE mode in the given frequency band. We believe that the proposed absorber finds applications in RADAR stealth.","PeriodicalId":201547,"journal":{"name":"2021 IEEE Indian Conference on Antennas and Propagation (InCAP)","volume":"49 21","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120822117","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 designs utilize a half-mode substrate integrated waveguide (HMSIW) resonator. The HMSIW technology was employed to realize the filtenna compactness, and a via-slot combination was organized to increase the functioning bandwidth, exhibiting two resonances in the respective passband. Besides, the design has been scaled for dual-frequency channel applications. The dual-channel for transceiver application was apprehended by arranging the scaled version of single-channel filtenna. Finally, dual-channel filtenna was fabricated and its performance was validated experimentally. The measured results are in good agreement with the simulated counterpart. The results show that the design exhibits impedance bandwidths of around 3.0 % i.e., 8.63-8.88 GHz and 4.2% i.e. 9.26-9.66 GHz for lower and upper-frequency pass channels, respectively. The proposed design has a consistent broadside radiation pattern and polarization in the operating bands, manifesting the proposed filtenna can be a promising candidate for multi-service wireless communication systems.
