A vacant-quarter ring connects orthogonal dipole arms to introduce the required 90° phase difference for generating CP radiation. To reduce the profile of the antenna, an AMC reflector is positioned beneath the radiator. The AMC reflector consists of hybrid metallic patterns printed on a substrate, where two different types of unit cells are arranged in the center and around the periphery separately to expand the in-phase reflection bandwidth. Additionally, metallic strips are added around the edge of the ground to improve the axial ratio and radiation pattern at lower frequencies. Measured results indicate that the impedance bandwidth and the axial ratio bandwidth of the antenna are 1.51 GHz to 5.13 GHz (109%) and 1.54 GHz to 3.57 GHz (79.5%), respectively. The antenna gains maintain 6.3 dBic to 8.3 dBic within the whole operating bandwidth. Furthermore, the antenna features a low profile of 0.13<italic>λ<sub>L</sub></i> corresponding to the lowest operating frequency.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3278-3282"},"PeriodicalIF":4.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998233","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 monopulse functionality is achieved using a gap-waveguide-based <inline-formula><tex-math>$2times 2$</tex-math></inline-formula> step-horn-array feed with a feeding network comprising 3 dB couplers and adaptive phase shifters. The antenna achieves an ultrahigh-gain of 50 dBi through integration of the feed with a Gregorian reflector antenna and employs beamsteering by offsetting the feed from the subreflector focus. However, the feed offsetting degrades the null depth in difference (<inline-formula><tex-math>$Delta$</tex-math></inline-formula>) patterns. Therefore, a new phase compensation strategy is proposed, involving a codesign of adaptive phase shifters with the offset by using a numerical phase compensation function quantified in this work based on simulation data through GRASP and CST. The fabricated antenna demonstrates reflection coefficients below <inline-formula><tex-math>$-10$</tex-math></inline-formula> dB for both polarizations over 71 GHz to 86 GHz. The measured radiation patterns and gains align closely with the simulated results. The system achieves a maximum gain of 50.48 dBi, with beamsteering within <inline-formula><tex-math>$pm 2^circ$</tex-math></inline-formula> from boresight and a maximum steering loss of 0.96 dB. The null depth of all <inline-formula><tex-math>$Delta$</tex-math></inline-formula>-beams is maintained above 20 dB.

The unit cell of the sensor consists of a spiral structure and a square metal frame, which generates the EIT. Experimental and calculated transmission spectra are in good agreement with the simulated results. Analysis of the electric field distributions, magnetic field distributions, and surface current distributions reveals that the EIT is primarily caused by spoof electric localized surface plasmons and electric dipole interactions, further supported by multipole scattering theory. The proposed sensor retains consistent sensitivity under oblique incidence conditions from 0° to 60° while maintaining polarization angle independence. The metasurface sensor achieves a measured sensitivity of 3.7 GHz/RIU, closely matching the simulated sensitivity of 4 GHz/RIU, highlighting its superior sensing performance. This work provides a novel approach for metasurface sensors and demonstrates significant potential for applications in detection.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3258-3262"},"PeriodicalIF":4.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998112","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}
