摘要：
A rectangular waveguide fed by a grounded coplanar waveguide (GCPW) is investigated using the finite-difference time-domain (FDTD) method. A patch is used to couple energy ro the rectangular waveguide (RW) by placing the waveguide opening around the patch. The coupling from the GCPW to the patch is accomplished via an open end. For a IO dB rerum 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 is found to have good insertion-loss characteristics, which verifies that power is indeed coupling to the waveguide, (C) 2001 John Wiley & Sons, Inc.
