Abstract :
A microstrip patch antenna directly fed by a grounded coplanar waveguide (GCPW) is investigated using the finite difference time domain (FDTD) method. Moreover, the patch is used to couple energy to a rectangular waveguide (RW) by placing the waveguide opening around the patch. For a 10 dB return loss. A relative bandwidth of 14% is obtained for a GCPW-to-RW transition. A back-to-back GCPW-to-RW transition is analyzed and found to have good insertion loss characteristics which verifies that power is indeed coupled to the waveguide.
