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.

Multi-band monopole antenna for a mobile communications device

The invention relates, inter alia, to a wireless portable device for radio communication, comprising at least one antenna element (), at least one ground-plane (), radio frequency communication circuitry () and at least one matching network (). The device is arranged for communication involving, at least, receiving and processing a signal in accordance with a communication system having a bandwidth with a lower frequency limit (f) and an upper frequency limit (f). The antenna element is a non-resonant antenna element for frequencies from said lower frequency limit (f) up to said higher frequency limit (f). Another aspect of the invention involves two antenna elements () tuned around two different central frequencies within a frequency band, and a switch () for selectively operatively connecting one of said at least two antenna elements to a radio frequency communication circuitry ().

Wireless portable device including internal broadcast receiver

One aspect of the invention relates to an antenna for a wireless device having spring contact elements based on strips () that, before bending, are housed in at least one gap () in a main body () of the antenna. The invention provides for a reduced stamping area overhead while allowing the spring contacts embodied by the strips to be placed close to the perimeter of the smallest possible rectangle that can house the main body. This can be helpful for mounting the antenna close to an edge of a printed circuit board () while not extending beyond said edge.
