Abstract
A slot antenna including: a dielectric substrate; a conductor pattern formed on a first surface of the dielectric substrate; a ground layer formed on a second surface of the dielectric substrate; a feeding point disposed at substantially a center of one side of the conductor pattern; a microstrip line extending from the feeding point to substantially a center of the conductor pattern; and a slot made with a predetermined width at a position at which the slot straddles a center line of the dielectric substrate, the center line passing through the feeding point, in the ground layer.
Claims6
A slot antenna comprising:
- a dielectric substrate;
- a conductor pattern formed on a first surface of the dielectric substrate;
- a ground layer formed on a second surface of the dielectric substrate;
- a feeding point disposed at substantially the center of one edge of the conductor pattern;
- a microstrip line extending from the feeding point to substantially a center of the conductor pattern;
- a slot in the ground layer having a predetermined width at a position at which the slot straddles a center line of the dielectric substrate, the center line passing through the feeding point;
- and
- an electric resistor loaded over the slot such that both ends of the electric resistor are in contact with the ground layer.
A slot antenna comprising:
- a dielectric substrate;
- a conductor pattern formed on a first surface of the dielectric substrate;
- a around layer formed on a second surface of the dielectric substrate;
