Abstract :
This paper presents the analysis of a coupling scheme for potential applications in planar phased array antennas. The configuration uses two microstrip substrates and an intervening stripline substrate to facilitate vertical signal distribution from RF circuit elements to patch antennas. The power is coupled between the different layers through apertures in the common ground planes of adjacent substrates. A full wave electromagnetic analysis based on the three dimensional transmission line matrix (3D-TLM) method is used to model the microstrip to stripline coupling discontinuity. The results obtained by this numerical analysis are compared to measured data (at around 5 GHz).
