Document Type and Number:
WIPO Patent Application WO/2019/130771
Kind Code:
A1
Abstract:
The present invention improves isolation characteristics of an antenna array. In an antenna array (100) relating to one embodiment of the present invention, an isolation element (113) is formed between a first antenna element (111) and a second antenna element (112) in a plan view from the first normal line direction of the isolation element (113). A first distance between the first antenna element (111) and a first ground electrode (190) is different from a second distance between the isolation element (113) and the first ground electrode (190). A third distance between the second antenna element (112) and the first ground electrode (190) is different from the second distance. The isolation element (113) is separated from the first antenna element (111) in a plan view from the second normal line direction of the first antenna element (111). The isolation element (113) is separated from the second antenna element (112) in a plan view from the third normal line direction of the second antenna element (112).
