Abstract :
A K-band four-element linear phased array of printed dipole antennas has been designed and tested. This array radiates in the end fire direction and is suitable for large two-dimensional arrays. A coplanar waveguide (CPW) is used for the microwave distribution system. A CPW to twin strip transition is used to interface with the printed dipole antennas. MMIC (microwave monolithic integrated circuit) phased shifters are used for phase control. This array demonstrates the advantages of CPW for MMIC integration and microwave signal distribution. The radiation characteristics of the antenna are excellent.<>
