Multiple frequency band antenna and antenna system using the same
First Claim
1. An antenna comprising:
- a substrate including a first surface and a second surface;
a radiating unit formed on the first surface of the substrate;
a slot formed by the radiating unit that is closed at one end and open at an opposite end; and
a feed unit formed on the second surface of the substrate in an area that corresponds to an area on the first surface of the substrate between the center of a length of the slot and the closed end of the slot and configured to be in an on or off position to resonate the antenna in a single frequency band in the on position and resonate the antenna in a plurality of frequency bands in the off position, wherein the feed unit has a perpendicular shape.

Abstract
A multiple frequency band antenna is provided that includes a radiating unit having a slot formed on a first surface of the substrate that is closed at one end and open at the other end, and a feed unit formed on a second surface of the substrate to pass through an area on the second surface that corresponds with the same area on first surface between the center and the closed side of the slot. The feeding unit comprises at least one switch which adjusts the size of an area for feeding power to the antenna. The radiating unit is resonated in a plurality of frequency bands when the switch is turned off, and the radiating unit is resonated in a single frequency band which is different from the plurality of frequency bands when the switch is turned on. Consequently, an antenna is implemented for use in multiple frequency bands.

19. An antenna system to transmit or receive wireless communication signals, comprising:
an antenna including; a substrate having a first surface and a second surface opposite to the first surface; a radiating unit formed on the first surface of the substrate including a rectangular slot formed by the radiating unit, the slot including a length having two ends including a closed end and an open end opposite the closed end and having a center line perpendicular to the length located between the open and closed ends; and a feed unit formed on the second surface of the substrate including a first portion formed at a location on the second surface corresponding to a same location on the first surface, wherein the same location is between the center line and the closed end of the slot; and a control unit to control the feed and resonate the antenna in a single frequency when the feed unit is in an on position and resonate the antenna in a plurality of frequencies different from the single frequency when the feed unit is in an off position, wherein the feed unit has a perpendicular shape. - View Dependent Claims (20, 21, 22, 23, 24, 25)
