First Claim
1. A mobile communications device, comprising:
- an exterior housing comprising a plurality of sides;
an electronics assembly comprising a ground and at least one feed port, the electronics assembly substantially contained within the exterior housing; and
an antenna component comprising;
a radiator element comprising a first surface, and configured to be disposed proximate to a first side of the exterior housing;
a feed conductor coupled to the at least one feed port, and configured to couple to the radiator element at a feed point;
a ground feed coupled between the first surface and the ground; and
an additional ground feed coupled between the first surface and the ground, the additional ground feed disposed at a first distance from the ground feed.

Abstract
A chassis-excited antenna apparatus, and methods of tuning and utilizing the same. In one embodiment, a distributed loop antenna configuration is used within a handheld mobile device (e.g., cellular telephone). The antenna comprises two radiating elements: one configured to operate in a high-frequency band, and the other in a low-frequency band. The two antenna elements are disposed on different side surfaces of the metal chassis of the portable device; e.g., on the opposing sides of the device enclosure. Each antenna component comprises a radiator and an insulating cover. The radiator is coupled to a device feed via a feed conductor and a ground point. A portion of the feed conductor is disposed with the radiator to facilitate forming of the coupled loop resonator structure.
