Design of 1:4 Power Divider Using Artificial Magnetic Conductor Packaging for Millimeter-wave Application

A novel design of 1:4 power divider with equal amplitude and phase using artificial magnetic conductor (AMC) packaging is proposed for millimeter-wave signal distribution and routing application. The prototype of the novel design has been fabricated and simulated. Furthermore, the performance of the proposed design is compared with the conventional microstrip line (MSL) 1:4 power divider. The results show meaningful improvement that the design can effectively minimize the insertion loss of output ports since the transmission line is surrounded by mushroom-like AMC periodic structure which generates a stop band, suppressing cavity modes and radiated, leaky, and surface wave.
