Abstract
Radial line slot antennas (RLSAs) are designed for high gain millimetre wave systems. Two types of RLSA are tested in the 60 GHz band: one is the conventional structure consisting of three separate parts, two conducting disks and a foaming dielectric material, while the other is a PTFE substrate which seems to be more suitable for mass production. The antenna characteristics are measured in the 60 GHz band and an excellent efficiency of 50% at 33 dBi is obtained
