Original Kurzfassung:
In this letter, a novel transition between a rectangular
waveguide and coupled microstrip lines is presented. A differential
microstrip patch antenna (DMPA) inside the waveguide acts as a
radiation element. The antenna is composed of the main patch,
the short-end parasitic patch, and the matching network. By
implementing the short-end parasitic patch, the bandwidth of
differential mode signals is greatly increased, while transmission
of common mode signals is strongly suppressed. Back-to-back
arrangements of such a transition were fabricated and measured.
The results show that the 10 dB return loss bandwidth reaches
14.5 GHz, and the insertion loss at the center frequency (96 GHz) is
0.5 dB. Such a transition is suitable for numerous millimeter-wave
applications.
