1. A microwave applicator comprising a body that comprises dielectric material including a void in the dielectric material, and conductive material deposited in the void by a deposition process to create a conductive feature that adheres directly to the dielectric material, thereby to form a feed for coupling energy into the dielectric material,
wherein the conductive feature adheres directly to the dielectric material and forms part of a feed for coupling electromagnetic energy via the conductive material into a waveguide comprising the dielectric material to an end of the microwave applicator such that the electromagnetic energy is transmitted through the dielectric material of the waveguide to an end of the microwave applicator for placing adjacent to or in contact with the tissue;
wherein the applicator comprises conductive material deposited on an outer surface of the body and further comprises:
a conductive link from the conductive material in the void to the conductive material deposited on the outer surface,
wherein the outer surface of the conductive material is configured for connection to a coaxial feed and the conductive link is arranged so as to launch the electromagnetic energy as a transverse electric (TE) mode.
