Antenna solution for future communication devices in mm-wave range

Different types of printed antennas for millimeter ranges such as high gain (narrow beam) with linear and circular polarization, sector antennas with azimuth angle of 60/spl deg/, 90/spl deg/ and 180/spl deg/, and omnidirectional antennas are proposed. All types are suitable for integration with active microwave and millimeter wave amplifiers, and down and upconvectors. Also, the proposed sector and omnidirectional antennas are practically applicable for the lower microwave range of 5 GHz that is included in the new generation of communication systems for 60 GHz range.
