Title:
ANTENNA APPARATUS AND WIRELESS COMMUNICATION DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/085055
Kind Code:
A1
Abstract:
This antenna apparatus has: a power feed point; a first antenna conductor that extends from the power feed point and has a width that gradually increases away from the power feed point; a second antennal conductor that faces the front end edge of the first antenna conductor with a gap therebetween; a first connection part that connects the front end edge of the first antenna conductor and the second antenna conductor via a capacitor; and a second connection part that connects the front end edge of the first antenna conductor and the second antenna conductor via an inductor or a zero-ohm resistor. A first connection point between the first connection part and the first antenna conductor is closer to the center of the front end edge of the first antenna conductor than a second connection point between the second connection part and the first antenna conductor.
