Classification: CPC H | IPC H

Claim 16:
17. A mobile device comprising:
one or more processors;
telecommunication circuitry configured to provide telecommunications; and
an antenna system coupled to the telecommunication circuitry, the antenna system comprising:
an antenna radiating element configured for at least one of RF signal transmission or RF signal reception, the antenna radiating element comprising a ground leg and a feed leg;
a connector coupled to a transmission line, the transmission line comprising an inner conductor and an outer conductor;
a feed connection coupled to the feed leg and configured to couple the feed leg to RF circuitry via the connector; and
a ground connection coupled to the ground leg and configured to couple the ground leg to ground via the connector, the ground connection including one or more electromagnetically coupled regions comprising a spiral planar portion;
wherein the ground leg is electrically coupled to a portion of an outer ring of the spiral planar portion;
wherein the feed connection is coupled to the inner conductor of the transmission line via the connector and the ground connection is coupled to the outer conductor of the transmission line via the connector, and
wherein the one or more electromagnetically coupled regions are configured to increase an electrical length of the ground connection; and
wherein the antenna radiating element is configured to radiate at a radiating wavelength and wherein the one or more electromagnetically coupled regions are configured to provide the electrical length of the ground connection as one quarter of the radiating wavelength at the ground leg.
