Abstract :
The paper presents an open-circuited type transition between microstrip line and substrate integrated waveguide (SIW) fabricated on a low temperature co-fire ceramic (LTCC) substrate. The energy is coupled to the waveguide through a via probe from the feeding microstrip line. The stripline pad to the via probe is introduced to improve the transition performance. The structure height of 176 μm which equals 0.073 guided wavelength is very short in microwave system. One single LTCC transition exhibits 10% bandwidth (58-64GHz in the center frequency 60.5GHz) for -15dB return loss and 2dB insertion loss in the center frequency.
