Innovatively, a dual-layer saucer-shaped ME-dipole is first designed for achieving a wide DP impedance bandwidth of 53% (23.7 GHz to 40.8 GHz), while maintaining a compact element size of 3.5 mm×3.5 mm×1.1 mm. Besides, the antenna also exhibits a flat gain response with a peak gain of 7.2 dBi and stable radiation patterns characterized by low cross-polarization levels below −20 dB. To demonstrate the reliability of the proposed concept, a 1 × 4 DP antenna array prototype is then implemented, manufactured, and measured. The broad measured impedance bandwidth of 50.5% (24.4 GHz to 40.9 GHz) with a peak gain of up to 12.4 dBi is achieved. Convincing experimental results corroborate the effectiveness of these designs. The exhibited performance metrics including wideband, stable radiation, compact size, high system integration, easy assembling, low cost, and so on, distinguish the proposed antenna array as a prospective choice for diverse burgeoning fifth and sixth-generation (5G/6G) mmWave applications.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3039-3043"},"PeriodicalIF":4.8,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998298","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}

A center-fed, center-symmetric patch is proposed to achieve a compact 1-bit multipolar patch design. Fishbone-shaped slots and interdigital capacitors are introduced to optimize impedance matching and far-field radiation. By integrating the radiating element with a 1-bit feed network, the design enables four types of linear polarization (LP) and dual circular polarization (CP) radiation with 2-bit phase resolution, all within a low-profile structure. As each element enables 2-bit phase and polarization reconfiguration, the array’s beam direction and polarization types can be flexibly controlled by adjusting the coding sequence. Based on the 2-bit polarized reconfigurable element, an 8 × 8 reconfigurable 2-bit antenna array is fabricated and tested to verify the beam-scanning performance of the antenna at the polarization of <inline-formula><tex-math>$x$</tex-math></inline-formula>-pol.

A beam-steerable antenna element is realized by feeding a pair of shorted patches with two separate ports. The main novelty is that the main-beam direction and radiation-null position of the proposed antenna pair can be tuned by controlling the excitation phase and amplitude of two ports, respectively. No active RF switch or varactor with dc biasing circuit is required. Furthermore, a millimeter-wave phased array is made up using proposed beam-steerable antenna pairs. By controlling the element-level amplitude and phase together with the array factor, the beam-scanning angle of the array is enhanced, and the sidelobe level is simultaneously suppressed in the process of beam scanning. The proposed array achieves a high peak gain of 13.1 dBi and a wide scanning range of ±70°, maintaining a low sidelobe level of smaller than −10 dB in the frequency band of 26 GHz to 30 GHz. Compared with previous related works, the advantage of the proposed array lies in high gain, simple structure, wide-angle beam scanning capability and good sidelobe suppression.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"3029-3033"},"PeriodicalIF":4.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998314","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}
