Coplanar waveguide antenna arrays for MIC/MMIC at millimetre wave frequencies

Abstract

Two kinds of new broadside coplanar waveguide (CPW) antenna arrays are proposed and their performances are confirmed by experiments at a frequency of about 37.5 GHz. They have completely printed structures and can be used in CPW MIC/MMIC operating up to millimetre wave frequencies. The array element spacings are appropriate and grating lobes are effectively prevented.
