Miniaturized Semi-lumped UWB Bandpass Filter with Improved Out-of-band Performances

In this article, a miniaturized ultra-wideband (UWB) bandpass filter with improved out-of-band performance is presented, based on the combination of low-pass and high-pass filters. The UWB filter is realized in a semi-lumped technology, using microstri...
Since the Federal Communications Commission's (FCC) release of the frequency band from 3.1 to 10.6 GHz for commercial purposes, 1 the UWB radio system has been receiving great attention from both academy and industry. As an essential component, UWB bandpass filters, with good performance, compact size and easily-implemented structures,...
