Abstract

The present invention relates to antenna arrangement for a portable device, wherein the antenna arrangement comprises a main radiating element (1) and a diversity radiating element (2). The main radiating element (1) is configured to be tuned (4) to part of a receiving frequency band of said antenna arrangement, and the diversity radiating element (2) is configured to be tuned (5) to another part of the receiving frequency band.

Description

technical field [0001] The present invention relates generally to antennas and in particular to an antenna structure for a portable device with receiver diversity. Background technique [0002] The market for portable radio communication devices such as mobile phones, PDAs, laptop computers and similar devices is today highly competitive which places high demands on manufacturers. Further, the antennas of such devices are often only available in confined spaces of different shapes. Contents of the invention [0003] It is therefore an object of the present invention to provide an antenna structure for a portable device which can be reduced in size without degrading performance. [0004] This object and others are achieved according to the invention by an antenna structure and a portable device as defined respectively in the appended claims. [0005] An antenna structure for a portable device is provided, the antenna structure comprising a main radiating element and a div...
