Flexible substrate antenna and antenna device

摘要

This disclosure provides a flexible substrate antenna and antenna device including a flexible substrate antenna. The flexible substrate antenna includes a first parasitic radiation electrode and a second parasitic radiation electrode provided on the flexible substrate, where a leading ends (open ends) of the first parasitic radiation electrode and the second parasitic radiation electrode face each other with a slit of a predetermined gap therebetween. Further, a capacitive feed electrode is formed on the flexible substrate at a position facing the first parasitic radiation electrode, and is configured to capacitively feed power to the first parasitic radiation electrode.
