A prototype of the barrel Tracking Detector of the Compact Muon Solenoid (CMS) experiment proposed for LHC was built and tested in a beam and in a magnetic eld of up to 3 T. It contained 6 microstrip gas chambers, 25 cm long, and 3 double-sided silicon microstrip detectors, 12.5 cm long. We report some preliminary results on the performance of the chambers.
Many detection methods have been applied to detect radon gas. Due to the low noise and high resolution of gas detectors compared to semiconductor detectors or scintillation detectors, using them to detect alpha radiation is very considerable. Microstrip proportional detector is also included in this group and it has not been used for the detection of radon. In this article, response of the micr...
In this paper an Artificial neural network (ANN) design technique for a Stub Microstrip Band-pass filter is presented. Essential dimensions of the microstrip filter layout are used to get the relationship in the inputoutputs of ANN model. This paper presents the design and analysis of Stub Microstrip Band-pass Filter at midband frequency 1.8 GHz which gives improved bandwidth and minimum insert...
3.1 INTRODUCTION This chapter explains the methods to improve the directivity, and bandwidth of microstrip antenna array, using EBG structures and the FSS as a superstrate layer. This chapter also details the concept, principles of operation and the geometries of the unit cell of various EBG structures used, along with the microstrip antenna array configuration. Using the Multiconductor Transmi...
This paper presents air gap aperture coupled microstrip antenna for dual-band operation over the frequency range of (2.9 to 6.0 GHz). This antenna differs from any other microstrip antenna with their feeding structure of the radiating patch element. Input signal couples to the radiating patch trough the aperture that exists on the ground plane of microstrip feed line. The dual-band achieved by ...
Fractal geometries are found attractive to designers seeking for compact size microwave circuits and antennas. In this paper, Peano fractal based open-loop resonators are adopted to design dual-band microstrip band-stop filters (PSFs). The suggested filter structure is essentially based on that of the conventional open-loop rectangular microstrip resonators. The resonators of the proposed PSF s...
In our paper, an inset-fed microstrip patch antenna has been designed and the dependency of resonant frequency on the notch gap and the feed line geometry has been studied. Our study suggests that a narrower notch resulted in better impedance matching. A design rule has also been formulated and presented the performance of the proposed design. Key-Words: Inset-fed, microstrip antenna
⎯ This paper is dedicated to simulate a rectangular patch antenna by using the software HFSS. Microstrip or patch antennas are becoming increasingly useful because they can be printed directly onto a circuit board. Microstrip antennas are becoming very widespread within the mobile phone market. Patch antennas are low cost, have a low profile and are easily fabricated.
In this paper, a compact microstrip resonant cell is proposed. Designed based on the hairpin structure, the proposed resonator provides wide stop-band and sharp skirt for low-pass filters. By cascading two of these resonators, a microstrip low-pass filter with cut-off frequency of 1.69GHz is designed and fabricated. According to experimental results, this filter has a small normalized circuit s...
