“…Such high isolation is usually achieved by a combination of antenna isolation enhancement, analog filtering, and digital interference cancellation [5]. Therefore, antennas with high isolations (> 25 db) are desired to relieve the pressure on the sequential processing and improve the dynamic range of the wireless connectivity [6,7].…”

A space-shared full-duplex antenna with high isolation is proposed for universal serial bus (USB) dongles. A compact antenna with a compact size of 22 mm x 4 mm comprises a loop and dipole antennas, working as a vertical monopole and a horizontal dipole, respectively. The dipole-type is fed by a microstrip-slotline transition with filtering characteristics of odd-mode bandpass and even-mode bandstop, avoiding the even-mode excitation for the loop antenna. The inherent isolation is caused by the orthogonality of the modes and the even-mode suppression (caused by the microstrip-slotline transition). Thus, high port isolation, low envelope correlation coefficients (ECC), and high efficiency are achieved across the 5G band of 3.4-3.6 GHz.

Accurate knowledge of multi-beam radiation patterns of millimeter-wave (mmWave) phased arrays is key to mmWave radio system performance. The multi-beam radiation patterns can be measured by conventional antenna test ranges in a sequential manner. However, these tasks can be time-consuming and low-efficient in practice, especially for large-scale arrays with many beam-steering states. To address this problem, this article proposes a multi-beam reconstruction method, which can measure all possible steered beams in a fast and efficient manner. In the proposed method, multiple beam patterns are reconstructed synchronously by a fast element pattern retrieving method based on a few sparse measurement samples, which were obtained in a multi-probe setup or with the help of a turntable in a single probe setup. The proposed method is experimentally validated in a compact antenna testing range (CATR) setup at 28 GHz for a 4 × 4 mmWave phased array with an integrated antenna-in-package (AiP) design. The experimental results show that the reconstructed array multi-beam patterns by the proposed method are comparable to the conventional CATR measurement results but in a faster way, which validates the effectiveness of the proposed method.
