Title:
OPTICAL CONTROL TYPE PHASED ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/009796
Kind Code:
A1
Abstract:
An optical control type phased array antenna (1) is provided with: a plurality of antenna elements (111 to 11N); multi-wavelength light source (20); an optical demultiplexing circuit (21, 22) that separates a plurality of optical signals and local oscillation light from output light of the multi-wavelength light source (20); light modulators (311 to 31N) that, by modulating the plurality of optical signals with output signals of the plurality of antenna elements (111 to 11N), generates a plurality of modulation optical signals; an optical coupler (33) that multiplexes the plurality of modulation optical signals and the local oscillation light and generates multiplexed light, and distributes the multiplexed light into reception optical signals of a plurality of channels; and an optical dispersion compensation circuit (40) that compensates a phase difference among the plurality of modulation optical signals by performing dispersion compensation on each of the reception optical signals.
