Document Type and Number:
WIPO Patent Application WO/2020/144994
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide, for example, a small antenna which can achieve impedance matching at a plurality of resonant frequencies, and a communication device including the antenna. The antenna comprises a conductor plate, for example. The conductor plate has a slot and a branch slot, wherein the branch slot has one end connected to the slot and the other end which, when viewed from the one end, extends along the slot in an antinode direction of an electric field at the lowest-order resonant frequency of the antenna, and is short-circuited in the conductor plate.
