In this paper, three novel compact metamaterial unit-cells are proposed. The proposed unit-
cells are based on the concept of the stepped-impedance resonator (SIR) technique which …

Targeting the range defined by the FCC (Federal Communication Commission) in 2002 for
ultra-passband bandpass filters, ie, 3.1 to 10.6 GHz, this article presents a simple compact …

In this paper two UWB (Ultra Wide Band) antennas and a UWB filter are reported. First
antenna is circularly-slotted-flower-shaped (CSFS) patch antenna and second one is CSFS …

This paper reports a narrowband bandpass filter with low insertion loss and compact size.
The presented filter has a symmetrical structure and consists of a high impedance coupled …

This paper aims to present a highly selective, compact size new ultra-wideband (UWB)
bandpass filter with three sharp notches for UWB indoor applications. The fundamental …

This article encompasses the design of compact ultra-wideband (UWB) bandpass filter with
low insertion loss and high selectivity using circular open-circuited stubs (COSs). Low …

A compact bandstop filter composed of eight folded stepped-impedance resonator cells for
triple-band stopband is presented. Based on the analysis of unit structure's characteristic …

A novel compact and highly selective Ultra Wide Band (UWB) filter is proposed using
multimode resonator (MMR) technology. To begin with, the filter's ultra-wideband …

One major problem in mixer based RF down-converters and superheterodyne receivers is
the presence of image frequencies. There have been a number of approaches, both in …

This paper introduces a compact configuration of bandpass filter using multi-mode resonator
(MMR) structure with high selectivity and wide upper stopband for ultra-wideband (UWB) …
