Abstract:

This paper presents 2-dimensional (2-D) 4 x 4 phased array control circuit for 8-bit infinite phase shifters. By calculating the control words to the phase shifters using full adders at the edges of the phase shifters, it is possible to steer the beam in two dimensions simply by inputting the horizontal and vertical phase difference words. The prototype control circuit with the infinite phase shifter generated phase shifts of 3.5 GHz continuous wave (CW) independently and arbitrarily in the horizontal and vertical directions.

I. Introduction

Beamforming using phased array antennas is being applied to Sub-6 frequencies and millimeter wave 5th generation mobile communication systems (5G), and as frequencies become higher, the need for Beyond 5G (6G) is increasing [12]. To implement a high-frequency phased array, a method of stacking multiple analog front-end boards containing antenna elements is currently being considered [3]–[5]. In such a system, it is necessary to wire multi-bit phase control bus between boards. For example, if a 4 x 4 phased array is implemented using 8-bit phase shifters, a 128-bit control bus is required between the DSP and the array antenna. This becomes one of the implementation issues.
