DIELECTRIC WINDOW ANTENNAS FOR ELECTRONIC DEVICES
First Claim
1. An electronic device with a logo antenna, comprising:
- a conductive housing wall;
a dielectric logo structure in the conductive housing wall that serves as a dielectric antenna window for the logo antenna; and
an antenna resonating element for the logo antenna that is mounted behind the dielectric logo structure, so that radio-frequency antenna signals pass from the antenna resonating element through the dielectric logo structure.

Abstract
Logo antennas are provided for electronic devices such as portable computers. An electronic device may have a housing with conductive housing walls. A logo antenna may be formed from an antenna resonating element such as a patch antenna resonating element, a monopole antenna resonating element, or other antenna resonating element structure. A conductive cavity may be placed behind the antenna resonating element. A dielectric antenna window that serves as a logo may be used to cover the antenna resonating element. The dielectric antenna window may be mounted in an opening in the conductive housing walls. A positive antenna feed terminal may be coupled to the antenna resonating element. A ground antenna feed terminal may be coupled to the cavity and portions of the conductive housing walls. The dielectric antenna window may be shaped in the form of a logo.
