First Claim
Patent Images
1. A multi-band monopole antenna for a mobile communications device, comprising:
- a common conductor having a feeding port for coupling the antenna to circuitry in the mobile communications device;
a first radiating arm coupled to the common conductor and having a meandering section extending from the common conductor in a first direction and a contiguous extended section extending from the meandering section in a second direction, the contiguous extended section extending in a substantially opposite direction as the meandering section; and
a second radiating arm coupled to the common conductor.

Abstract
A multi-band monopole antenna for a mobile communications device includes a common conductor coupled to both a first radiating arm and a second radiating arm. The common conductor includes a feeding port for coupling the antenna to communications circuitry in a mobile communications device. In one embodiment, the first radiating arm includes a space-filling curve. In another embodiment, the first radiating arm includes a meandering section extending from the common conductor in a first direction and a contiguous extended section extending from the meandering section in a second direction.
