초록

A microstrip filter has been designed and fabricated in hairpin form on a GaAs substrate and its characteristics such as the insertion loss, return loss, and bandwidth have been investigated. The presented filter is realized with relatively small size, 4.5 by 3.6 mm. The insertion loss and return loss of the filter are 1.17 dB and 30 dB, respectively. The filter exhibits 3 dB-bandwidth of 350 MHz at the center frequency, 5.890 GHz. The experimental results show good agreement with the numerical ones. However, the measured center frequency is about 100 MHz higher than the designed one.
