Broadband printed millimeter-wave antennas

We present a theoretical and experimental investigation of a class of broadband, printed millimeter-wave (mm-wave) antennas. The fundamental element of the proposed antennas is the aperture stacked patch of which variations are developed that can be used for point-to-multipoint radio communications, and also be readily integrated with photonic and millimeterwave devices for application in fiber-radio systems. The proposed printed antennas operate over the entire Ka-band frequency range (26-40 GHz) and therefore can be incorporated in a multitude of radio service applications. Experimental verification of all the designed configurations is given.
