Claim:
1. An antenna configuration for use in a mobile telecommunications device to provide three-dimensional, orthogonal polarisation, said antenna configuration comprising: a half mode substrate integrated waveguide (HMSIW) antenna comprising two parallel conductive plates separated by a dielectric, said HMSIW antenna having a substantially rectangular shape comprising a first edge, a second edge perpendicular to the first edge and connected to the first edge by a first corner, a third edge opposing and parallel to the first edge and connected to the second edge by a second corner, and a fourth edge opposing and parallel to the second edge and connected to the first edge by a third corner and to the third edge by a fourth corner, wherein the first and second edges are open for radiation; a first slot antenna including a first dielectric strip extending from the third corner in a direction which is parallel to and collinear with the first edge and away from the first corner; and a second slot antenna including a second dielectric strip extending from the second corner in a direction which is parallel to and collinear with the second edge and away from the first corner; wherein said two parallel plates of the HMSIW antenna lie in a plane defined by the first and second dielectric strips, and wherein the first slot antenna is responsible for linear polarisation in a direction parallel to the first edge, the second thick-slot antenna is responsible for linear polarisation in a direction parallel to the second edge, and the HMSIW antenna is responsible for linear polarisation in a direction perpendicular to the parallel conductive plates of the HMSIW antenna.
