Title:
PLATE-LIKE ARRAY ANTENNA AND WIRELESS MODULE
Document Type and Number:
WIPO Patent Application WO/2019/012732
Kind Code:
A1
Abstract:
The present invention makes it possible to appropriately set antenna directivity, and realize increased antenna gain. A plate-like array antenna 20 comprises: a dielectric substrate; a ground conductor layer 37 formed on one face of the dielectric substrate; a plurality of serial-type radiation element rows 41 formed on the other face of the dielectric substrate; and a parallel feeder line which is formed on the other face of the dielectric substrate and which supplies high-frequency power between a power supply end point 45s on the other face of the dielectric substrate and the serial-type radiation element rows 41. The parallel feeder line 45 branches from the power supply end point 45s toward radiation elements 42 on the end closest to the power supply end point 45s, connecting the radiation elements 42 and the power supply end point 45s, and the path distance from the power supply end point 45s to the end radiation elements 42 is the same for all of the serial-type radiation element rows 41.
