Abstract

A novel multifunctional reconfigurable filter with three different transmission modes using transversal signal-interaction principles is proposed. These three operational modes allow to reconfigure the engineered filtering device as ultra-wideband bandpass filter, narrow-band bandpass filter (NB BPF), and ultra-wideband band-stop filter (UWB BSF). By turning on/off the RF switches, the transmission lines and stubs can be dynamically connected or disconnected so that the three transmission modes can be discretely selected. For the UWB-BPF mode, the 3-dB bandwidth is 95.7% (1.51-4.38 GHz) with minimum in-band insertion loss of 0.94 dB. For the NB-BPF mode, the 3-dB bandwidth is 25.3% (2.55-3.29 GHz), the minimum in-band insertion loss is 0.8 dB, and the stopband rejection is higher than 11.6 dB. For the UWB-BSF mode, the 3-dB bandwidth is 106% (1.41-4.59 GHz) with in-band insertion loss above 10 dB.
