Title:
BUTLER MATRIX CIRCUIT, PHASED ARRAY ANTENNA, FRONT END MODULE, AND WIRELESS COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2019/116648
Kind Code:
A1
Abstract:
[Problem] To provide a Butler matrix circuit which has volume and power consumption that can be further reduced, and with which symmetric radiation characteristics can be achieved. [Solution] Provided is a Butler matrix circuit provided with: four processing circuit-side terminals; four antenna-side terminals; a first 90° hybrid coupler connected to the first and second processing circuit-side terminals; a second 90° hybrid coupler connected to the third and fourth processing circuit-side terminals; a third 90° hybrid coupler connected to the first and third antenna-side terminals; a fourth 90° hybrid coupler connected to the second and fourth antenna-side terminals; a first 90° delay circuit provided between the first 90° hybrid coupler and the third 90° hybrid coupler; and a second 90° delay circuit provided between the first 90° hybrid coupler and the fourth 90° hybrid coupler.
