Abstract

A dielectric radiator antenna arrangement (18) for a communication device having a ground plane (17) comprises a dielectric volume having a central axis (z) in the centre of the volume provided as a normal to the ground plane and mode exciting elements (22, 24, 26). The mode exciting elements include a first mode exciting element (22) provided in or attached to the dielectric volume and extending in a plane provided at a first distance (d1 ) from the central axis perpendicular to the ground plane and a second mode exciting element (24) provided in or attached to the dielectric volume and extending in a plane provided at a second distance (d2) from the central axis perpendicular to both the ground plane and the plane of the first mode exciting element. The antenna arrangement can be used for simultaneously transmitting and receiving more than one signal at one frequency with reduced coupling.

Description

technical field [0001] The present invention relates to the field of antennas, and more particularly to a dielectric resonator antenna arrangement, such a dielectric resonator antenna arranged above a ground plane, and to a portable communication device comprising such an antenna arrangement . Background technique [0002] MIMO (Multiple Input Multiple Output) is an antenna technology for wireless communications in which multiple antennas are used at the source (transmitter) and target (receiver). The antennas at each end of the communication circuit are combined to reduce errors and optimize data speed. MIMO is especially important in communication, such as in digital TV, WLAN and in mobile communication. [0003] Therefore, it is especially important to use this technology in wireless communication, for example in portable communication devices, such as cellular telephones. [0004] However, cellular telephones are required to be small in size, so incorporating more tha...
