The antenna is composed of dielectric units with varying lengths, engineered to facilitate the conversion of linearly polarized electromagnetic waves into circularly polarized waves. A rigorous theoretical analysis of these dielectric units reveals their ability to achieve a 90° phase difference between the two orthogonal electrical components within a substantial bandwidth. Subsequent empirical measurements corroborate these findings, affirming the antenna’s capacity to deliver a prominently wide axial ratio (AR) bandwidth. To achieve circular polarization (CP) and enhancement on gain, the design culminates in the construction of a convex lens, formed using these dielectric units. The proposed antenna demonstrates a remarkable impedance bandwidth spanning from 21.7 to 67 GHz, where the voltage standing wave ratio (VSWR) remains consistently below 2. In addition, the AR bandwidth is over 115.9% from 18 to 67 GHz, ensuring AR below 3 dB. The measured peak gain of the antenna registers at 20.6 dBic. This study extensively explores the intricate relationship between the relative dielectric constant and the dielectric unit. This exploration has yielded a novel and cost-effective solution for achieving ultra broadband CP with high gain, specifically tailored for MMW applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"8980-8990"},"PeriodicalIF":4.6,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859127","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}

This truncated PC serves as a zero-phase shift line with impedance matching to its feed line. Waves traveling along this zero-phase shift line are fast waves, capable of radiating broadside beams to function as a leaky wave antenna with two symmetrical beams.

However, available multifunctional vortex wave generators are often constrained by dispersion effects, limiting their operation to only a few frequency points or within narrowband. In this article, a method for generating dual-mode OAM vortex waves under broadband conditions is proposed. Initially, by employing the Pancharatnam-Berry (PB) phase concept, 360° coverage of the reflective phase can be achieved on a single dielectric substrate. Subsequently, to address the reduced purity of OAM modes caused by metasurface dispersion under broadband conditions, a distance inversion method is proposed. A prototype is designed, manufactured, and measured to demonstrate the effectiveness of the proposed method. Both simulated and measured results confirm that the metasurface can generate OAM beams with \u0000<inline-formula> <tex-math>$l ,, = ,, -1$ </tex-math></inline-formula>\u0000 and \u0000<inline-formula> <tex-math>$l ,, = ,, +2$ </tex-math></inline-formula>\u0000 within a bandwidth from 8 to 14 GHz (54.55% relative bandwidth).

However, imperfect filtering structures are prone to generate radiation leakages toward nonboresight directions at the stopband, resulting in degraded filtering characteristics in the peak realized gain response. This article introduces two new CP filtering antennas operating at 60 GHz: one involves a single antenna element and the other involves a folded reflectarray antenna (FRA), both presenting an outstanding peak realized gain filtering response. A unique folded double-layer substrate-integrated-waveguide (SIW) feeding structure incorporated with a self-energy-bounding CP radiator is proposed for the antenna element. No filtering structure is needed in the radiator. The feeding structure, independent of the resonator cavity, inherently minimizes radiation leakages and can produce three radiation nulls, guaranteeing the desired filtering characteristic. The proposed CP filtering antenna element is then integrated with a folded metasurface to create a new CP filtering FRA. Both antennas feature high selectivity, ample stopband rejection, stable CP radiation in upper millimeter-wave (mmW) frequencies, and easy integration, making them suitable for 60-GHz communications and sensing systems applications.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"8958-8970"},"PeriodicalIF":4.6,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859129","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}

Such functionality of independent real-time control for dual-CP beam is enabled by combining the merits of the Berry phase technique (BPT), dynamic phase technique (DPT), and reconfigurable technique. Based on the theory that an arbitrary linear polarized (LP) wave can be decomposed into a left-handed CP (LHCP) wave and a right-handed CP (RHCP) wave, the proposed array adopts the LP element to generate two independent switchable CP beams. A digital phase shifting network, comprising a switchable multiport phase shifter and two adjustable microstrip line phase shifters, is developed to provide the independent phase control for two orthogonal CP waves. To validate the concept, a \u0000<inline-formula> <tex-math>$1times 8$ </tex-math></inline-formula>\u0000 PAA operating at 4.3 GHz is designed, fabricated, and measured. The experimental results agree well with the simulated ones for the six different beam states, thus verifying that the wavefront of the two orthogonal CP waves can be manipulated independently. The joint bandwidth of the 3-dB axial ratio (AR) and the 3-dB gain for all operating states can achieve 18.6%, covering from 3.9 to 4.7 GHz. The proposed dual-CP dual-beam PAA with independent and dynamic controllability could be applied in satellite communications, point-to-multipoint communications, and so on.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"72 12","pages":"9002-9011"},"PeriodicalIF":4.6,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859348","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 resulting LoS path topology is used to simulate wireless fronthaul links based on industry-standardized fronthaul interfaces across the urban environment. In considering the stringent fronthaul interface requirements for a representative 5G radio configuration, the suitability of emerging mmWave and sub-THz transport bands between 71.124 and 174.8 GHz to fulfill the wireless fronthaul-centralized RAN (C-RAN) deployment is analyzed.
