Abstract
Official abstract text for this publication.
Examples are disclosed that relate to an antenna formed in a chassis of a device. One example provides a wireless device comprising a chassis and a chassis antenna formed at least in part by a dielectric gap between a body of the chassis and the chassis antenna, where a first end of the chassis antenna is defined by a cut-out in the chassis and where a second end of the chassis antenna being conductively connected to a body of the chassis. The wireless device further comprises a modem, and a coupled feed connected to the modem and capacitively coupled to the chassis antenna.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wireless device comprising: a chassis; a chassis antenna formed at least in part by a dielectric gap between a body of the chassis and the chassis antenna, a first end of the chassis antenna defined by a cut-out in the chassis and a second end of the chassis antenna being conductively connected to the body of the chassis; a modem; a coupled feed connected to the modem, located adjacent to the first end of the chassis antenna, and capacitively coupled to the chassis antenna; and a coupled ground conductively connected to the body of the chassis, and capacitively coupled to the coupled feed to form a loop antenna such that the loop antenna provides one or more additional frequency bands for communication. 2. The device of claim 1 , wherein the coupled ground is configured to comprise a tunable impedance. 3. The device of claim 1 , further comprising an antenna tuner connected to the body of the chassis and connected to the chassis antenna. 4. The device of claim 3 , wherein the antenna tuner is configured to have a tunable impedance. 5. The device of claim 1 , wherein the dielectric gap comprises a polymer. 6. The device of claim 1 , wherein the device comprises a laptop computer. 7. A wireless device comprising: a chassis; a chassis antenna formed at least in part by a dielectric gap between a body of the chassis and the chassis antenna, a first end of the chassis antenna defined by a cut-out in the chassis and a second end of the chassis antenna being conductively connected to the body of the chassis; a modem; a coupled feed connected to the modem and capacitively coupled to the chassis antenna; and a coupled ground conductively connected to the body of the chassis and capacitively coupled to the coupled feed to form a loop antenna such that the loop antenna provides one or more additional frequency bands for communication. 8. The device of claim 7 , wherein the coupled ground is configured to have a tunable impedance. 9. The device of claim 7 , wherein the coupled feed is located adjacent to the first end of the chassis antenna. 10. The device of claim 7 , wherein the coupled feed is configured to excite the chassis antenna at a fundamental frequency of the chassis antenna. 11. The device of claim 7 , wherein the coupled feed is configured to excite the chassis antenna at one or more harmonic frequencies of a fundamental frequency of the chassis antenna. 12. A wireless device comprising: a chassis; a chassis antenna formed at least in part by a dielectric gap between a body of the chassis and the chassis antenna, a first end of the chassis antenna defined by a cut-out in the chassis and a second end of the chassis antenna being conductively connected to the body of the chassis; a modem; a coupled feed connected to the modem and capacitively coupled to the chassis antenna; a coupled ground conductively connected to the body of the chassis and capacitively coupled to the coupled feed to form a loop antenna such that the loop antenna provides one or more additional frequency bands for communication; and an antenna tuner connected to the body of the chassis and connected to the chassis antenna. 13. The device of claim 12 , wherein one or more of the chassis antenna and the coupled feed are configured to operate at a frequency band within a range from 600 MHz to 5 Ghz. 14. The device of claim 12 , wherein the dielectric gap comprises a polymer. 15. The device of claim 12 , wherein the coupled feed is configured to excite the chassis antenna at a fundamental frequency of the chassis antenna. 16. The device of claim 12 , wherein the coupled feed is configured to excite the chassis antenna at one or more harmonic frequencies of a fundamental frequency of the chassis antenna. 17. The device of claim 12 , wherein the wireless device comprises a laptop computer.
