The 1-bit phase DMSs achieve more than 10 dB monostatic RCSR at 4.1–17 GHz (122.3%) under the normal incidence of both linearly polarized (LP) and circularly polarized (CP) waves. Then, the Pancharatnam-Berry (P-B) phase generated by rotating the entire periodic polarization conversion unit cell array, which can eliminate the impact of coupling-related distortion in the unit cell array, is applied to construct the circular phased DMSs, which the phases of lattices are varied along the circular ring, for both RCSR and OAM wave generation under the far-field incident wave. The circular phased DMSs can achieve more than 10 dB monostatic RCSR at 4–17.1 GHz (124.2%) under the normal incidence of both LP and CP waves. Moreover, they also generate the OAM waves when illuminated by a CP wave.

In this article, we present the design and implementation of a coherent distributed massive multiple-input-multiple-output (MIMO) channel sounder operating at 5 and 6GHz with a bandwidth of 400MHz based on the NI USRP X410. Through the integration of multiple transceiver chains and radio frequency (RF) switches, the design facilitates the use of a larger number of antennas without significant compromise in dynamic capability. Our current implementation is capable of measuring thousands of antenna combinations in tens of milliseconds. Every radio frequency switch is seamlessly integrated with a 16-element antenna array, allowing phase-coherent multinode dual-polarized double-directional dynamic channel measurements for multistatic integrated sensing and communication (ISAC) applications. In addition, the channel sounder features real-time processing to reduce the data stream to the host computer and increase the signal-to-noise ratio. The correct operation of the sounder is demonstrated through two measurements in an indoor laboratory environment. The first measurement entails a single-antenna robot as a transmitter and 128 distributed receiving antennas. The second measurement demonstrates a passive sensing scenario with a walking person. We evaluate the results of both measurements using the super-resolution algorithm space-alternating generalized expectation maximization (SAGE). The results demonstrate the great potential of the presented sounding system for providing high-quality radio channel measurements, contributing to high-resolution channel estimation, characterization, and active and passive sensing in realistic and dynamic scenarios.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 4","pages":"2074-2085"},"PeriodicalIF":4.6,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821595","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}

An approach is first introduced for designing broadband TM-polarized ASS, which utilizes the angular dispersion characteristic of the cutoff frequency in the parallel-plate waveguide (PPW). Furthermore, additional short-circuited strips are incorporated between adjacent metal plates to produce angle-dependent transmission zeros (TZs), thus enhancing the angular selectivity. Subsequently, to achieve dual polarization, a polarization-decoupling method is proposed that integrates an ASS valid only for TE polarization into a TM-valid PPW-based structure. The TE-valid ASS functions as a second-order spatial filter, which utilizes the dispersion of dielectric transmission lines (DTLs) to manipulate its angular responses. Finally, the TE- and TM-valid ASSs are co-designed and one dual-polarized ASS is resulted accordingly. The proposed ASS exhibits angular selectivity over a wide frequency band from 6.5 to 9 GHz, with a low profile of <inline-formula> <tex-math>$0.65lambda_{mathrm {C}}$ </tex-math></inline-formula> (25 mm).

The experimental campaign is conducted in an urban park, under tree shadowing environment. The ergodic capacities are calculated 5.2 b/s/Hz for line-of-sight (LOS), and 4.4 b/s/Hz for nonline-of-sight (NLOS) trajectories, respectively, substantially enhanced compared with the single-input-single-output (SISO) cases. The encountered capacity variations are associated with the propagation geometry and the UAV flight path, as well as with the elevation angle and distance between the related terminals. From the multiplexing assessment analysis, the DP-MIMO channel has been shown its favorability for adopting beamforming methods. A new stochastic model is also suggested that represents the channel matrix employing jointly the inverse Gaussian and Rayleigh distributions. Promising results are delivered, where the adopted model predicts conveniently the channel capacity under the existence of tree shadowing.

A novel all-metal modular tightly coupled dipole array (TCDA) is proposed and realized for the first time in this article. The proposed TCDA has uniquely shaped planar dipole arms, effectively minimizing the antenna profile. Meanwhile, the novel element facilitates the modular assembly of arrays with arbitrary sizes and shapes, enhancing the ease of replacement in case of damage to some elements. The array edge truncation effect can, moreover, be alleviated by just using half-sized elements (HSEs), thereby effectively reducing the aperture sizes of traditional TCDAs with dummy elements. Simulation results show that the proposed TCDA is able to operate at 4.67:1 bandwidth (0.45–2.1 GHz) for broadside, and is able to scan up to 60° in the E-D-plane and 45° in the H-plane within 0.5–2 GHz, with a rather low profile of only <inline-formula> <tex-math>$0.48lambda _{mathrm {H}}$ </tex-math></inline-formula> at the highest operating frequency.

The 1-D scanning capability of this architecture is realized based on compact linear arrays rather than individual units, which utilizes fewer active channels, leading to a substantial decrease in power consumption, heat dissipation requirements, and overall system cost, particularly for large-scale phased-array implementations. The fully polarized waves are generated by the superposition of two orthogonal linearly polarized waves. With the amplitude and phase of the two orthogonally polarized ports precisely controlled by active chips, the fully polarized beam-scanning capability is achieved. The theoretical formulation of full-polarization beam-scanning synthesis of this architecture is derived. Then, a <inline-formula> <tex-math>$16times 24$ </tex-math></inline-formula>-scale active phased array constructed from 16 linear subarrays is designed, fabricated, and measured to validate the effectiveness of the architecture. The operating bandwidth of the antenna covers 10.7–12.75 GHz. The prototype demonstrates a scanning range of ±45° across six typical polarization states, including linear <italic>x</i>-polarization, linear <italic>y</i>-polarization, linear ±45° polarizations, and both left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP). Moreover, employing the proposed architecture, the power of each unit in this <inline-formula> <tex-math>$16times 24$ </tex-math></inline-formula> phased array is only 0.006 W and the ratio of array unit numbers to active channel numbers is 12.
