SLOT ANTENNAS FOR ELECTRONIC DEVICES
First Claim
1. A slot antenna comprising:
- a ground plane element having an elongated slot portion that is elongated along a first axis and having, at opposing ends of the elongated slot, first and second openings that are wider than the elongated slot portion along a second axis that is perpendicular to the first axis, wherein the first and second openings are different in size.

Abstract
Slot antennas are provided for electronic devices such as portable electronic devices. The slot antennas may have a dielectric-filled slot that is formed in a ground plane element. The ground plane element may be formed from part of a conductive device housing. The slot may have one or more holes at its ends. The holes may affect the impedance characteristics of the slot antennas so that the length of the slot antennas may be reduced. For example, the holes can be used to synthesize the impedance of the slot antennas so that the slot antennas have a resonant frequency that is different from their natural resonant frequency. The holes may affect the impedance of the slot antennas in multiple radio-frequency bands.
