Document Type and Number:
WIPO Patent Application WO/2017/119223
Kind Code:
A1
Abstract:
A Luneberg lens antenna device (1) comprising a Luneberg lens (2), a plurality of patch antennas (6A-6C), and a plurality of low-frequency antennas (12A-12C). The Luneberg lens (2) is formed in a cylindrical shape and has three dielectric layers (3-5) having different dielectric constants, laminated in the radial direction thereof. The plurality of patch antennas (6A-6C) comprise ground electrodes (11A-11C) covering the outer circumferential surface side of radiation elements (7A-7C) and constitute a high-frequency band MIMO antenna. The plurality of low-frequency antennas (12A-12C) are monopole antennas using the ground electrodes (11A-11C) and constitute a low-frequency band MIMO antenna.
