This paper, for the first time, presents a new technique to overcome the problems of realizing multiple band rejection notches in high-order miniaturized UWB filters employing the E-shape microstrip structure. The new technique employs double layer substrate where on the bottom layer the main filter is developed and on the top the circuit for band rejection notches is etched. These two filter circuits...

Recently a design technique was proposed for realizing miniaturized high-order UWB bandpass filters using a direct cascade of E-shape microstrip structures. This class of filters has one transmission zero at the upper stopband. In order to increase the lower stopband attenuation, this paper presents an alternative design technique to generate a further transmission zero in the lower stopband, leading...
Recently a new systematic design rule was proposed to realize high-order UWB bandpass filters using cascaded E-shape microstrip structures. The responses of these miniaturized filters show one transmission zero at the upper stop-band. In order to improve the selectivity at the lower stop-band, this paper proposes a new generation of miniaturized high-order UWB bandpass filters having an attenuation...
In order to prevent interference with some selected narrowband communication channels, UWB filters with rejections at these bands are preferred or sometimes necessary for some UWB systems. In this paper, for the first time, a technique for generating rejection notches in the miniaturized UWB filters employing the E-shape microstrip structure is presented. It is shown the attenuated bands can be achieved...

Based on a unique E-shape microstrip structure and its equivalent circuit, a compact and highly selective seventh-order UWB bandpass filter is developed for small wireless communication systems. This highly selective UWB bandpass filters offers ultra-wide stopband attenuation. The filter composes of six grounded middle stub E-shape microstrip structures connected in cascade using short sections of...
One type of E-shape microstrip structure is composed of λg/2 hairpin resonator loaded by a grounded stub at its middle. For the first time, using an equivalent circuit for this structure, high-order UWB bandpass filter design technique is presented based on cascading E-shape microstrip structures. Two third-order UWB bandpass filters are designed, simulated, fabricated and measured. These filters...
Recently the E-shape microstrip structure was proposed in order to develop miniaturized ultra-wide band (UWB) bandpass filters. In spite of its attractive features, no thorough analysis of this structure is available in the literature. In this paper, the E-shape microstrip structure with grounded center conductor is analyzed and, for the first time, an approximate equivalent circuit is proposed for...
