“…The sparse recovery for the sub-array-based PWG is a 0norm minimization problem and is, therefore, NP-hard [13]. In [11], a brute force method is adopted. However, the optimal number of antennas in each sub-array is typically unknown.…”

“…The basic principle of PWG is to coherently synthesize the plane wave field in the quiet zone (QZ) via properly allocating excitations for the contained antennas. Various methodologies, e.g., in [6][7][8][9][10][11][12], have been developed to determine the optimal locations and excitations of PWG antennas for a highquality and cost-effective plane wave synthesis. For example, a systematic guideline on the PWG geometrical design and the stability of the solution are studied in [9].…”

“…Applying the sparse representation theory, [10] proposed a novel PWG design method with fewer radiating sources. Most of them, however, are limited to narrowband applications and require rigorous amplitude and phase feeding control, except for the tapering methods [11]. However, it is typically applied for the PWG with a large aperture and is not ideal for the small anechoic chambers [8].…”

This letter proposes a novel ultra-wideband plane wave generator (PWG) design methodology suitable for a low-cost small anechoic chamber. Several novel strategies are proposed to handle various crucial concerns in practice to make the proposed methodology reliable and robust. Specifically, the subarray-based amplitude-only excitation method is capable of reducing the required number of control channels without the need for phase shifters, which can significantly simplify the feeding network complexity. One major concern of the PWG application is the non-negligible multipath reflections in small anechoic chambers. Thus, a novel regression approach, imposing the constraint of maximum energy outside the quiet zone (QZ), is implemented to suppress the reflection level. For the design of the PWG layout, a compressed sensing-based adaptive backtracking orthogonal matching pursuit (ABOMP) algorithm is proposed. In the simulation, a spherical test zone supporting the ultrawideband frequency over 2.4-5 GHz is synthesized with the proposed methodology, and the effectiveness and robustness are comprehensively investigated.

Phased array calibration is typically carried out in plane-wave conditions, which requires expensive far-field setups. This letter presents a novel phased array calibration method based on measured complex array signal, which works in the cost-effective compact testing setup. The basic principle is to employ multi-probe antennas in a short measurement distance such that we can effectively retrieve the array element patterns in the boresight direction based on the recorded complex signals at the multiple probes using the interpolation technique. Both theoretical derivations and measurement validations are provided to demonstrate the effectiveness of the proposed method.

“…The measurement time also becomes prohibitive when the electrical size of the AUT becomes large. Different FF methods have been extensively employed in the industry, e.g., direct-far-field (DFF), compact antenna test range (CATR) and plane wave generator (PWG) [11,12]. The basic principle of DFF is that a plane wave at the antenna can be directly approximated if the measurement range is no smaller than the Fraunhofer FF distance.…”

In production testing, it is of importance to measure the key radiation parameters of an antenna under test (AUT), e.g., main beam peak and direction, sidelobes, and null depth and direction in a cost-effective setup with a short measurement time. As a result, practical measurement setups are often compact and equipped with only a few probes (or probe locations). However, these system limitations would introduce errors for antenna testing. This problem has become even more pronounced for 5G radios due to utilization of large-scale antenna configurations and high frequency bands. Spherical near-field measurements are nowadays an accurate and mature technique for characterizing AUTs, which however, necessitates a full spherical acquisition, leading to a long measurement time. Singlecut near-to-far-field transformation is a promising strategy since most of the key AUT parameters are available in the single-cut pattern and it requires much reduced measurement time. In this work, a simple and flexible scheme is proposed to evaluate errors introduced by limitations in practical setups for single-cut far-field (FF) antenna radiation pattern reconstruction, where the near-field data can be easily generated and modified according to the limitations introduced in practical multiprobe anechoic chamber setups, e.g., measurement distance, truncation range, and sampling interval. The reconstructed FF pattern is obtained using a commercial near-field to far-field transformation tool, SNIFT. The proposed scheme is numerically validated via comparing the reference FF pattern of a 4 × 8 uniform planar array composed of ideal Hertzian dipoles and reconstructed FF pattern. With the proposed scheme, the impact of practical system limitations on single-cut reconstruction accuracy can be easily analyzed.Index Terms ─ Antenna pattern measurement, nearfield far-field transformation, near field measurement, over-the-air testing, and single-cut antenna pattern.
