This paper presents a novel approach for designing planar multimode wideband bandpass fllters with good selectivity. The multimode resonator is composed of an open-ended microstrip line with length of half-wavelength (‚=2) and several radial-line s

This letter presents two ultra-wideband (UWB) antennas with 3.4/5.5 GHz dual-notched bands. The U- and V-slots are used to reject the frequency band (3.3–4.2 GHz) limited by C-band satellite communication and Wimax systems. Another rejection band (

In this paper, two hexagonal meander loop resonators with circular patches and their applications to filters are presented. Only one mode characteristic has been affected by changing the size of the circular patch, which is different from the convent

A novel triple-mode hexagonal bandpass fllter with capacitive loading stubs is introduced in this article. The technique, adding an open capacitive stub, is applied to enlarge the equivalent self- capacitance of the resonator, which declines its reso

A compact microstrip triple-mode bandpass filter using half-wavelength (λ/2) open-ended microstrip line with double center loaded stubs is proposed in this article.By introducing a radial-line stub to the traditional dual-mode resonator, a triple-mo

Based on the center stub loaded theory, a new microstrip bandpass filter using circular double center stubs loaded resonator is presented in this paper. By changing the shape of the center loaded stubs, the transmission zero shifts from left to right
