ANTENNA CONFIGURATION FOR USE IN A MOBILE COMMUNICATION DEVICE

摘要

The antenna configuration disclosed herein can be used in a mobile telecommunications device to provide three-dimensional, orthogonal polarisation. The antenna configuration comprises a half mode substrate integrated waveguide (HMSIW) antenna, a first thick-slot antenna and a second thick-slot antenna. The HMSIW antenna comprises two parallel conductive plates separated by a dielectric. The HMSIW antenna has a substantially rectangular shape comprising a first edge, a second edge substantially perpendicular to the first edge and connected to the first edge by a first corner, a third edge opposing and substantially parallel to the first edge and connected to the second edge by a second corner, and a fourth edge opposing and substantially parallel to the second edge and connected to the first edge by a third corner and to the third edge by a fourth corner. The first and second edges are open for radiation. The first thick-slot antenna includes a first dielectric strip extending from the third corner in a direction substantially parallel to and collinear with the first edge and away from the first corner. The second thick-slot antenna includes a second dielectric strip extending from the second corner in a direction substantially parallel to and collinear with the second edge and away from the first corner. The two parallel plates of the I IMS1W antenna lie in a plane defined by the first and second dielectric strips. The first thick-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.
