摘要: This paper presents an analysis of a reconfigurable patch filter based on triple-mode circular resonator with four radial slots. The has been carried out thanks to the development new theoretical approach tunable coupling matrix. coefficients matrix related behavior have identified and some rules for their evolution derived. For proof-of-concept, bandpass designed continuous tunability obtained varactors connected across State-of-the-art results obtained, frequency tuning range 27% from 1.95 2.43 GHz change in fractional bandwidth 8.5% 31.5% respective frequencies. In entire range, return loss is better than 10 dB maximum insertion 2 dB. Due newly developed matrix, measurements, simulations, theory showed great agreement.
