We consider the problems of composite structures with metasurfaces for greater generality and applicability. The integral equations of the problems are formulated and discretised using Rao–Wilton–Glisson (RWG) basis functions through Galerkin's testing procedure. We also propose a technique for enforcing the boundary condition at the interface, which should be carefully considered within the problem formulation of composite structures. The proposed method is validated by using a circuit-analog-based absorber to extract the surface susceptibilities.

To address the strong coupling between nearby transmit and receive antennas, this study employs an improved quantum genetic algorithm (IQGA) to eliminate SI by combining digital self-interference cancellation (SIC) and adaptive beamforming (ABF). Through digital SIC, both transmit noise and transmit signals are suppressed. The objective of the transceiver beamformer is to further reduce SI through SIC while simultaneously achieving high transceiver gain in the desired direction. IQGA represents the weights of feasible transceiver beams using chromosomes. By updating the population through quantum rotation, quantum crossover and quantum mutation strategies, IQGA demonstrates improvements in convergence accuracy, convergence speed, and reliability. In comparison to traditional ABF approaches, IQGA eliminates the need for complex matrix calculations and numerical derivations, thereby simplifying the solution process. The simulation results indicate that by cancelling the SI component through SIC and ABF, an isolation of 159.78 dB can be achieved at a transmit power of 1000 W. This represents an improvement of 40.32 dB compared to SIC alone and 113.87 dB compared to scenarios without SIC and ABF.","PeriodicalId":13374,"journal":{"name":"Iet Microwaves Antennas & Propagation","volume":"19 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/mia2.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such benefits provide a deep insight into the device under test (DUT) performance; nevertheless, the realism achieved by OTA tests is still moderate in comparison to open-field tests. This contribution takes the OTA testing method for wireless devices and combines it with the wave field synthesis (WFS) technique to increase the efficiency, reliability and especially the realism of the tests. The main focus of this contribution is to use the aforementioned method to emulate realistic GNSS scenarios inside an anechoic chamber, where multiple virtual satellite signals are electronically generated in the far field along with their individual trajectories. For the validation and verification of the method, a commercial GNSS antenna and receiver are placed as the DUT inside the chamber. The WFS calibration methods implemented in an OTA testbed are described in detail along with the performance analysis obtained by each method. This study strives to establish the foundation for a forthcoming standardisation of the proposed methodology, applicable not only to GNSS devices but also to any variety of wireless devices.","PeriodicalId":13374,"journal":{"name":"Iet Microwaves Antennas & Propagation","volume":"19 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/mia2.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, adopting pixeled matrix modelling methods enhances the freedom of design. Next, the staircase approximation is utilised for the S-parameter curve, which also describes the required electromagnetic (EM) property to be used in the training process. These processed samples, along with their corresponding labels, are transformed and fed into ResNet for training. After these procedures, the structural matrix of the desired curve can be predicted through well-trained networks. To validate the effectiveness of the method, typical notched-band frequency selective absorbers (FSAs) are designed, while the reflective band can easily be adjusted.

In response to this challenge, a dual-band high-gain conical beam antenna with broad impedance bandwidth based on a nested horn operating at Ku-/Ka-band is presented in this paper. The nested horn excited by metal probes comprises a Ka-band circular waveguide horn and an outer nested Ku-band waveguide horn. The proposed antenna operates in the TM01 mode, demonstrating rotationally symmetrical field distribution, which enables the generation of conical beams. The utilisation of a ridge waveguide further widens the impedance bandwidth. The incorporation of dual reflectors enhances the directivity of electromagnetic wave propagation, leading to increased gain and a fixed beam pointing angle. The measured results show that the proposed antenna operates at 12.8–18 GHz in the Ku-band and 25.2–43.5 GHz in the Ka-band, with relative impedance bandwidths of approximately 33.8% and 53.3%, respectively, covering nearly the entire Ku-band and Ka-band.
