Calibration is essential to optimize the performance of any radio transceiver during its development and manufacturing processes. This paper proposes over-the-air (OTA) calibration methods based on measuring and calibrating the phases of phased array

Phased arrays in 5G millimeter wave (mmW) communication are used at both link ends to separate users and to enhance the link range. The radio hardware's RF performance metrics vary due to part-to-part variations within component tolerances. In this p

Abstract High throughput and ultra low latency are the main requirements for fifth generation (5G) mobile broadband communications. Densely populated urban environments require utilization of previously underutilized millimeter wave frequency spectru

This article presents a dual-band, dual-polarized antenna operating from 24 up to 40 GHz at 5G new radio (NR) millimeter-wave (mm-Wave) Frequency Range 2 (FR2) bands. A novel stacking arrangement of ring patches is proposed to achieve wide dual-band

Phased arrays have typically equal lengths for all antenna paths. This paper compares three phased array architectures for 5/6G applications. The first two arrays present unequal-length feeding networks, while the third array is the corporate-fed one
