Abstract
An antenna includes 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 another 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 closed in the conductor plate.
Claims11
An antenna comprising:
- a conductive plate,
- wherein:
- the conductive plate comprises a slot and a branch slot;
- one end of the branch slot is coupled to the slot;
- and
- another end of the branch slot is closed in the conductive plate and extends along the slot in a direction toward an antinode of an electric field at a minimum order resonance frequency of the antenna when viewed from the one end.
