Based on three high-order modes, the designed filtering DDPA achieves high-gain. Radiation nulls (Null 1 and Null 2) are generated by etching a parallel four-slot structure on the ground and the nonradiative mode. By etching the rectangular grooves on the DDP, using the inverted L-shaped defect structure and attaching the C-shaped stub to the microstrip line, better impedance matching and stopband suppression levels are obtained.

Measured results indicate that the bandwidth of relative impedance is 13.2% [(4.6 to 5.25) GHz]. The measured average realized gain and peak gain are 8.66 dBi and 9.85 dBi, respectively.

This, to the best of our knowledge, is the first of its kind and claims a twofold novelty: a stepwise development of complex multiunit defected ground geometry (DGG) based on a thorough scientific analysis and use of a machine learning-assisted global antenna optimization method, particularly, the parallel surrogate model-assisted hybrid differential evolution for antenna synthesis (PSADEA) algorithm, which is often more than ten times faster than popular global optimization techniques, while obtaining superior results. They result in highly optimal solutions considering multiple performances, i.e., reduction in cross-polarization (XP) radiations simultaneously over orthogonal (H-) and diagonal (D-) planes maintaining the primary gain unaffected. The proposed DGG has been satisfactorily tested with different patches and arrays fabricated in C band. Typically, 7.5 dBi to 8.0 dBi peak gain has been ensured along with 13 dB to 18 dB improvement in XP level over entire radiation planes. A 4-element array on an identical DGG promises over 40 dB co-to-XP isolation over the entire azimuth planes.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 4","pages":"1008-1012"},"PeriodicalIF":3.7,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143801077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tag, constructed with hybrid phase shift elements, possesses the capability to convert and independently control dual circular polarization. The reflection from left-handed circularly polarized (LCP) waves exhibits a higher monostatic radar cross section (RCS) than those from right-handed circularly polarized (RCP) waves within a certain angle range. The monostatic RCS difference between LCP and RCP depends on the tag incident angle, varying in magnitude as the angle changes. Therefore, the tag's incident angle can be obtained by comparing the measured difference with theoretically predicted values. A nine-element RFID tag was designed and fabricated, and its performance was validated through experiments. Experimental results confirmed significant distinguishability between the scattered LCP and RCP monostatic RCS patterns, aligning with simulated predictions. The proposed tag incident angle measurement method requires only a single RFID tag and a single reader. Additionally, the method is compatible with conventional positioning methods and can serve as an alternative method to enhance stability.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 4","pages":"1013-1017"},"PeriodicalIF":3.7,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed design consists of a square substrate integrated waveguide cavity (SSIWC), a truncated square patch with an etched U-shaped slot, and four parasitic shorted patches. The SSIWC, serving as a feeding cavity, and two metal posts are employed as perturbation elements to excite the degenerate modes in SSIWC. Initially, the energy couples from the SSIWC to the truncated square patch through a small square slot so as to obtain circular polarization with two AR minima. Then, four shorted patches are arranged around the truncated square patch to concurrently generate a third AR minimum and a radiation null, thus improving the AR bandwidth and the upper passband edge's roll-off rate. Finally, a U-shaped slot is utilized, introducing an extra radiation null to further enhance the upper stopband's suppression level and simultaneously optimizing the impedance and AR matching of the whole antenna. A fabricated prototype was measured, demonstrating an overlapped bandwidth (where |<inline-formula><tex-math>${it {S}}_text{dd11}$</tex-math></inline-formula>| ≤ −10 dB and AR ≤ 3 dB) of 4.63 GHz to 5.05 GHz (8.6%), and an average realized gain of 6.6 dBi with good filtering response.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 4","pages":"1028-1032"},"PeriodicalIF":3.7,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143800952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
