Title:
ANTENNA ELEMENT, ANTENNA MODULE, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/074377
Kind Code:
A1
Abstract:
A patch antenna (10) that comprises: a feed conductor pattern (12) that is formed on a dielectric layer (20); a ground conductor pattern (14) that is formed on the dielectric layer (20); and a first non-feed conductor pattern (11) and a second non-feed conductor pattern (13) that are formed on the dielectric layer (20) and are not set to a ground potential. The first non-feed conductor pattern (11), the feed conductor pattern (12), the second non-feed conductor pattern (13), and the ground conductor pattern (14) are arranged in that order in cross-sectional view and overlap each other in plan view. A resonant frequency f1 that is defined by an anti-phase mode current for the first non-feed conductor pattern (11) is higher than a resonant frequency f2 that is defined by an in-phase mode current for the feed conductor pattern (12). A resonant frequency f3 that is defined by an anti-phase mode current for the second non-feed conductor pattern (13) is lower than resonant frequency f2.
