“…Recently, there has been a great interest in balanced bandpass filters (BPFs) on account of high immunity to crosstalk and electromagnetic interference [1,2,3,4,5,6,7,8,9,10,11,12]. Considering the tunability and reconfigurability of RF/microwave system [13,14,15], the microstrip line resonator has been extensively utilized to design tunable balanced BPFs due to its simple manufacture process and easy integration with active devices. Accordingly, great efforts have been paid on tunable microstrip balanced BPFs [16,17,18,19,20,21,22,23,24].…”

“…Due to the development of wireless communication technique, great efforts have been paid on tunable and multi-purpose RF/microwave systems. [1][2][3][4][5] As one of the key devices, tunable bandpass filters (BPFs) are becoming research hotpots because of great potential for reducing the system size and complexity. [6][7][8][9][10] The frequency tuning range is the key performance of tunable BPFs.…”

“…In order to facilitate their deployment, multi-band bandpass filters (BPFs) with a highly selective response, low insertion loss (IL) and small physical size need to be incorporated in the RF front-ends of these systems in order to be able to acquire the bands of interest while suppressing the unwanted interfering signals. Therefore, the realization of filters with multi-band transfer functions has been an important topic of research [1][2][3][4][5][6][9][10][11][12][13][14][15][16][17].…”

“…Microstrip-based designs have been investigated in [3][4][5][6][7][8][9][10][11][12][13][14][15] as reduced-size alternatives. While they exhibit moderate IL levels (<2.5 dB in [3][4][5]), they suffer from closely spaced spurious responses.…”
