The antenna consists of a dual-fed stacked patch radiator cascaded with a simple dual-band dual-CP feeding network. First, the feeding network consists of a power divider cascaded with two transmission lines (TLs) with different lengths. Because of the dispersion characteristics of TLs, the phase differences of the two output ports are −90° and +90° at two bands, respectively. Second, a dual-fed stacked patch radiator operating at these two bands is cascaded with the feeding network, enabling dual-band dual-CP radiation.

Compared with the state-of-the-art designs, the proposed antenna offers low cost and easy integration due to its simple structure. The millimeter-wave (MMW) stacked patch antenna array is embedded in the weak electric-field (<italic>E-field) region of the antiphase TM20 mode and TM12 mode of the microwave (MW) dual-patch antenna. This design interleaves two antenna types within the same aperture, achieving natural isolation. Slots on the MW patch modify the current path of the antiphase TM20 mode and the TM12 mode, enabling dual-mode operation with low profile. The stacked patches provide wideband operation in MMW frequency band. Additionally, periodic slots on the MW patch facilitate MMW beam scanning, achieving ±45° beam scanning at both <italic>E- and <italic>H-planes. For demonstration, a prototype of the proposed MW and MMW shared-aperture patch antenna is fabricated and measured, which has a total size of 0.38λL × 0.48<italic>λL × 0.022<italic>λL (<italic>λL is the operating wavelength at 4.6 GHz in free space).

The performance of the crossover ring filter structure is first analyzed, revealing that different port selections yield distinct stopband effects. Specifically, exciting the horizontal ports of the crossover structure introduces a stopband at upper frequencies while selecting vertical ports generates a stopband at lower frequencies. Leveraging this phenomenon, two third-order crossover ring structures are orthogonally positioned beneath the radiating arms for dual-polarization operation realization. The integration of this structure enables the antenna to achieve the desired bandpass radiation response. For verification, the proposed antenna was fabricated and tested. The results indicate that the antenna achieves an impedance bandwidth of 1.88 GHz to 2.41 GHz, two controllable radiation nulls, and an out-of-band radiation suppression level exceeding 19 dB. These advantages make it an excellent candidate for base station antenna systems.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 9","pages":"2984-2988"},"PeriodicalIF":4.8,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997985","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}

However, the existing extraction methods inevitably introduce calculation errors, resulting in inaccurate extraction of it, which limits the improvement of recognition accuracy. To address these issues, physics-informed complex natural resonance frequency correction is proposed. First, a loss function based on target’s resonance scattering mechanism is designed. Physics is used to drive network to extract features, strengthening the physical constraints on the corrected data. Second, by introducing the idea of complex-valued neural network, a complex domain-variational autoencoder is designed, which considers the correlation between the real and imaginary parts of complex data, thereby excavating more internal features of data. Experimental results verify the effectiveness of the proposed method. Compared with the original data, the relative errors are reduced by 18.02% for the real part and 0.49% for the imaginary part.
