Abstract
A new half-mode frequency-tunable SIW (substrate-integrated waveguide) bandpass filter with a constant absolute bandwidth is presented in this paper. For achieving the constant bandwidth, we have developed new external and internal coupling structures capable of exhibiting specified coupling values over the frequency tuning range of the presented filter. Hence, the presented filter employs no tuning components in the coupling structures and this avoids the insertion loss increase due to tuning components. For verification, a second-order filter has been designed, fabricated, and measured. The filter has the insertion loss smaller than 2.0 dB over the frequency tuning range from 1.85 GHz to 2.3 GHz. The bandwidth slightly varies from 136 MHz to 142 MHz.
