The horizontally polarized TE\u0000<inline-formula> <tex-math>$_{{011+}delta }$ </tex-math></inline-formula>\u0000 and vertically polarized TM\u0000<inline-formula> <tex-math>$_{{02}delta }$ </tex-math></inline-formula>\u0000 modes of the cylindrical DRA are employed in this polarization-diversity antenna. The new mode combination is found to provide a small height-to-radius ratio of ~0.14, which is well suited for the low-profile design. In order to simultaneously expand the bandwidth of these two modes, an air ring covering the strong E-field regions of both modes is introduced into the lower portion of the cylindrical DRA. In this way, the bandwidths of the TE\u0000<inline-formula> <tex-math>$_{{011+}delta }$ </tex-math></inline-formula>\u0000 and TM\u0000<inline-formula> <tex-math>$_{{02}delta }$ </tex-math></inline-formula>\u0000 modes can be efficiently increased by 2.6 and 3.1 times, respectively, and the overlapping bandwidth of the diversity DRA also increases accordingly. The measured outcome demonstrates that the suggested omnidirectional polarization-diversity DRA exhibits strong performance, which can achieve a 25 dB minimum isolation and a 4.2 dBi maximum gain within a 12% overlapping bandwidth. Significantly, it necessitates a DR height of only \u0000<inline-formula> <tex-math>$0.08lambda _{text {o}}$ </tex-math></inline-formula>\u0000, a new record for the omnidirectional polarization-diversity DRAs.

The antenna employs a circular radiation patch and a rectangular slot in the ground plane, with optimized dimensions to achieve super-wide bandwidth. To address interference issues with co-existing narrowband systems, two inverse L-shaped stubs are connected to the ground plane, effectively rejecting the WiMAX spectrum. In addition, two circle-like ring slots are embedded into the radiation patch to create band-rejected features for WLAN and X-band downlink frequencies. Despite its compact size of \u0000<inline-formula> <tex-math>$14times 14$ </tex-math></inline-formula>\u0000 mm (\u0000<inline-formula> <tex-math>$0.13lambda _{text {g}} times 0.13lambda _{text {g}}$ </tex-math></inline-formula>\u0000), the antenna offers a bandwidth extending from 2.8 to over 20 GHz, making it suitable for UWB (3.1–10.6 GHz) and Ku-band (12–18 GHz) applications. This communication also explores the antenna’s impact on transmitting and receiving ultranarrow pulses for IR biomedical applications, assessed using the system fidelity factor (SFF). A noteworthy contribution of this work is the investigation of the time-domain properties of the proposed antenna in a typical indoor propagation channel. The simulated and measured results demonstrate the antenna’s favorable characteristics in both the frequency and time domains.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"9498-9503"},"PeriodicalIF":4.6,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859134","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 pattern reconfigurable structure is achieved by a pair of 3-D-printed arc-shaped parasitic metal panels, which are capable of high-gain beam scanning with ±24° in the H-plane and ±18° in the E-plane radiation, respectively, without the electrical controlling components. Moreover, by arranging the arc-shaped parasitic metal panels symmetrically, the half-power beamwidth (HPBW) of the antenna can be adjusted from 48° to 79°. The proposed DRA utilizes a stacked multilayer dielectric substrate structure to excite the HEM\u0000<inline-formula> <tex-math>$_{12sigma }$ </tex-math></inline-formula>\u0000 higher-order mode which improves the gain performance. Finally, the antenna achieved the maximum gain of 10.6 dBi in the operating bandwidth. The pattern reconfiguration through mechanical control avoids the extra insertion loss that could result from PIN diodes and allows for a high overlapped bandwidth in different radiation patterns. The measured overlap-operating frequency band and maximum gain of the antenna with different radiation states are 2.17–2.72 GHz (fractional bandwidth (FBW) of 22.49%) and 10.42 dBi, respectively. These values are well suited for the 2.4 GHz ISM band applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"9492-9497"},"PeriodicalIF":4.6,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859003","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 CP antenna element comprises several patch cells and an L-shaped strip with three branches on the same layer. The patch cells and the L-shaped strip excite four linear polarized modes, while three branches shift these modes to suitable frequencies using characteristic mode analysis. Furthermore, a two-port antenna is constructed by mirroring the CP antenna element, where the middle patch cells can further broaden the bandwidth and cancel opposite currents to provide 27.5 dB isolation.

In practice, however, the “double fading” effect undermines the application of RISs and constitutes a significant challenge to its commercialization. To address this problem, we present a novel 2-bit programmable amplifying transmissive RIS with a power amplification function to enhance the transmission of electromagnetic (EM) signals. The transmissive function is achieved through a pair of radiation patches located on the upper and lower surfaces, respectively, while a microstrip line connects two patches. A power amplifier, an SP4T switch, and a directional coupler provide signal amplification and a 2-bit phase shift. To characterize the signal enhancement of active transmissive RISs, we propose a dual radar cross section (RCS)-based path loss model to predict the power of the received signal for active transmissive RIS-aided wireless communication systems. Simulation and experimental results verify the reliability of the RIS design, and the proposed path loss model is validated by measurements. Compared with the traditional passive RIS, the signal power gain in this design achieves 11.9 dB.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"9239-9250"},"PeriodicalIF":4.6,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859089","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}
