Abstract

Two kinds of new broadside coplanar waveguide (CPW) array antennas are proposed.They can be connected with conductor backed CPW circuits more conveniently than the microstrip arrays because no transition is needed for the CPW feeder. The completely printed structure matches the requirement of MIC/MMIC up to millimeter wave frequencies, the grating lobes can be prevented by means of limiting the spacing between elements. Their performances are experimentally investigated at the Q-waveband. The transition between the CPW antenna and the testing waveguide are discussed.
