Circularly-polarized wave antenna device for wireless device mounted in motor vehicle, has auxiliary electrode provided along width direction of main electrode provided on base surface
Circularly-polarized wave antenna device for wireless device mounted in motor vehicle, has auxiliary electrode provided along width direction of main electrode provided on base surface
The radiation and ground electrodes (18,22) are formed on either surfaces of a base (11). A power supply unit (23) supplies excitation power to the radiation electrode which excites two resonance currents in the isolation degeneration mode. The radiation electrode has a main electrode (19) provided on the base surface, and an auxiliary electrode (20) provided along the width direction of the main electrode. An Independent claim is included for wireless device.
