High-frequency circuit and antenna module

Abstract

A high-frequency circuit includes a plurality of beam former ICs. The beam former IC includes a parameter acquisition unit and a set value acquisition unit. The parameter acquisition unit acquires a phase shift parameter related to phase shift of each of a plurality of antenna elements set corresponding to a direction of a beam-shaped high-frequency signal transmitted and received by each of the antenna elements. The phase shift parameter is acquired based on at least one phase gradient parameter related to a phase difference between the antenna elements adjacent to each other, a physical position of each of the plurality of antenna elements, and a density parameter related to resolution of a beam direction of the high-frequency signal. The set value acquisition unit acquires at least a set value of the phase shift of each of the antenna elements according to the phase shift parameter.
