摘要：
In this Letter, with the application of liquid crystal (LC) an electrically tunable microwave filter has been designed, manufactured, and characterized. The proposed compact filter has been realized on a particularly configured cavity which was constructed with low cost inverted-microstrip structures and conventional resonance structure. By applying low square-wave (1KHz) voltages, low power consumption is involved. The filter responses have been allocated at k-band of microwave frequency at which band many communications and radar applications applied. The proposed filter occupies a compact area of 19 mm x 17 mm only. The measured results have shown that the proposed filter realized the central frequency changing from 15.5 GHz to 16.5 GHz continuously with bias voltages changing between 0 and 10 V.
