Abstract :
This paper presents proximity coupled microstrip line T-junctions using a parasitic element for application as a DC free junction with highly isolated output branches. A parasitic patch resonator placed above the microstrip patch resonators gives tight coupling between input port and output branch. The FDTD simulation and experiments show that isolation between output ports is more than 10 dB without using any resistors
