Compact dielectric resonator antenna
First Claim
1. A dielectric resonator antenna arrangement to be provided on a ground plane, comprising:
- a dielectric volume having a central axis normal to the ground plane; and
at least three mode-exciting elements, including,a first mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a first distance from the central axis and being perpendicular to the ground plane,a second mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a second distance from the central axis and being perpendicular to both the ground plane and the plane of the first mode-exciting element, anda third mode-exciting element centrally disposed in the dielectric volume extending along the central axis in a direction normal to the ground plane, wherein each of the mode-exciting elements connects to a separate signal feeder.

Abstract
A dielectric radiator antenna arrangement for a communication device having a ground plane is provided. The antenna arrangement may include a dielectric volume having a central axis normal to the ground plane, and mode-exciting elements. The mode-exciting elements may include a first mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a first distance from the central axis perpendicular to the ground plane, and a second mode-exciting element provided in or attached to the dielectric volume and extending in a plane provided at a second distance from the central axis and 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.
