In this paper a high performance Ultra Wide Band microstrip bandpass filter is presented. The filter is designed using λ/4 short circuited stubs to improve the performance of UWB. The designed filter is based on 5th order chebyshev low pass prototype with .1 dB passband ripples. The filter with total size of 45×11 mm operates within 3.1310.4 GHz, produces a fractional bandwidth of 106%. The fil...

This article presents a simple method to design an ultra-wideband (UWB) bandpass filter (BPF) with notched band. The structure of the is and composed single half-wavelength resonator loaded three sets short-circuit step impedance stubs. An equivalent circuit model presented analyze resonance characteristics. Compared traditional quarter-wavelength uniform stub, novelty stub introduces two param...

The goal of this paper is to study a noisy WiFi range-only sensor and its application in the development of localization and mapping systems. Moreover, the paper shows several localization and mapping techniques to be compared. These techniques have been applied successfully with other technologies, like ultra-wide band (UWB), but we demonstrate that even using a much more noisier sensor these ...

Trilateration calculations are affected by errors in distance measurements from the set of fixed points to the object of interest. When these errors are systemic, each distinct set of fixed points can be said to exhibit a unique set noise. For ultra-wideband (UWB) indoor position tracking, the set of fixed points is a set of sensors measuring the distance to a tracked tag. In this paper we deve...

In this letter, two types of substrate-integrated defected ground structure (SIDGS) resonators (i.e., loaded-stub and C-shape resonators) are proposed for the ultra-wideband (UWB) bandpass filter (BPF) design. Coupled SIDGS can generate four transmission poles to achieve UWB response with low insertion loss in a compact size. Besides, spurious cancellation broad stopband is achieved by mutual s...
