A wide bandwidth is critical for mitigating these issues and improving channel capacity. This communication presents a compact implantable antenna that provides ultrawide bandwidth for leadless cardiac pacemakers (LCPs). The proposed antenna has an ultracompact size of 8.33 mm3, with a 10-dB bandwidth of 4.33 GHz (fractional bandwidth of 152.7%), spanning from 0.67 to 5 GHz. It covers the Industrial, Scientific, and Medical (ISM) bands (0.915 and 2.45 GHz), the Wireless Medical Telemetry Service (WMTS) band (1.4 GHz), and the midfield band (1.6 GHz). The simulation results demonstrate gains of −31.3 dBi at 0.915 GHz, −25.8 dBi at 1.4 GHz, and −21.9 dBi at 2.45 GHz. This antenna exhibits peak specific absorption rate (SAR) values of 320.4 W/kg at 0.915 GHz, 332.8 W/kg at 1.4 GHz, and 464.1 W/kg at 2.45 GHz. To ensure the reliability of the wireless communication link, the link budget is analyzed to estimate the range between the transmitter and receiver at data rates of 10 and 25 Mb/s. To validate the results, the manufactured antenna is tested with minced pork, demonstrating a satisfactory agreement between the measured and simulated outcomes.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 5","pages":"3310-3315"},"PeriodicalIF":4.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 realization of multibeamforming with TMAs based on amplitude modulation (AM) waveform has some disadvantages. First, this method, which is based on AM waveform, results in a significant reduction in array efficiency as the number of antennas increases. Moreover, only one antenna works at a time, thus the instantaneous power is very small. In this article, a new waveform based on phase modulation (PM) is proposed to realize multibeamforming, which ensures that each antenna is always active. As a consequence, instantaneous power is improved and the theoretical value of feeding network efficiency can reach 100%, which is independent of the number of antennas. In addition, the modulated waveform proposed in this article can be optimized by genetic algorithm (GA), which further improves harmonic efficiency. As a result, this method can efficiently enhance array efficiency while reducing hardware complexity and expense. Both numerical simulation and experiment show that the proposed method is effective.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"3654-3665"},"PeriodicalIF":4.6,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Operating from 24.5 to 27.5 GHz, the LWA consists of a vertically polarized (VP) patch array, a horizontally polarized (HP) printed dipole array, and a dual-channel gap waveguide (GW) that provides traveling-wave excitation. The VP patch array, located at the center of the antenna aperture, contains 80 slot-excited patches. The HP dipole array is divided into two subarrays distributed on both sides of the antenna aperture and is excited by slot-coupled microstrip lines. The VP and HP arrays are independent, enabling simultaneous control of both polarization beams. Due to the low profile of the printed dipole, the radiation aperture of the antenna can be fully utilized, providing the ability to expand in two dimensions. To achieve fixed-frequency beam scanning, each antenna unit has a 1-bit amplitude modulation capability, realized by electrically controlling the p-i-n diode. A dual-channel GW capable of transmitting both TE01 and TE10 modes is designed, and the stacked architecture makes it suitable for a compact DP antenna. A holographic method is employed to realize the beam scanning. Simulated and measured results verify that the proposed antenna can achieve fixed-frequency, wide-angle, and quasi-continuous beam scanning.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"3666-3679"},"PeriodicalIF":4.6,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 approach is based on a symmetric vertical crossed-loop antenna (SCLA) and involves both a frequency-domain calibration process and a time-domain reconstruction process.

The frequency band spans from ultralow frequency (<inline-formula> <tex-math>$10^{-25}$ </tex-math></inline-formula> Hz) to microwave frequency. The application of the Calderón preconditioner ensures that the impedance matrix is well-conditioned. Furthermore, the Filon-type method is integrated into the Calderón preconditioner to guarantee the accuracy of the oscillatory integral. In addition, by incorporating a block-matrix constraint condition, we obtain stabilized and well-conditioned dielectric formulations based on marching-on-in-degree (MOD) method. Expanding on these techniques, we propose a universal static error current subtraction (SECS) method, characterized by its simplicity of implementation, to attain an accurate solution for ultrawideband scenarios. Notably, the accurate results can be obtained from ultralow to high frequencies through single temporal simulation. Numerical examples demonstrate that the proposed approach is able to achieve stable and accurate ultra broadband solutions.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 6","pages":"4116-4121"},"PeriodicalIF":4.6,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
