A new approach for designing a narrow dual bandpass filter (BPF) using microstrip coupled line filter with new shaped of ‘bell’ structure resonator is presented in this paper. The proposed BPF consists of two fundamental resonant modes and the resonant characteristic has been investigated using Advanced Design System (ADS) software. To validate the design and analysis, the filter were fabricated and...
In this paper, an experimental procedure for designing a novel 5.8 GHz triangular microstrip loop resonator antenna is presented. The proposed antenna is fed by a microstrip feed line arrangement and excited by a coaxial feed probe. The antenna elements were rotated 90 degree clockwise about the z-axis in parallel with the microstrip feed. This was done in order to ensure a good proximity coupling...
This paper introduces the performance of an elliptical shaped antenna with random slots and compares the results between the original patch and the patch without both dots and connector. 5.8 GHz is the reference or desired frequency set for measuring the performance of this antenna. For the design, three elliptical shaped slots with different dimensions are deployed and connected to each other acting...
This paper introduces the performance of an elliptical shaped antenna with random slots and compares the results between the original patch and the patch without dots. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. For the design, three elliptical shaped slots with different dimensions are deployed and connected to each other acting as a main radiating...
This paper introduces the performance of an elliptical shaped antenna with random slots with the use of superstrate and compares the results between the original patch and the patch with superstrate layer but without dots. 5.8GHz is the reference or desired frequency set for measuring the performance of this antenna. The purpose of using superstrate is to optimize the gain and radiation efficiency...
In this paper an experimental study on a directional cylindrical dielectric resonator antenna (CDRA) at 5.8 GHz is discussed and presented. Dielectric resonator (DR) ceramic-base material is investigated in the design and it is found that it improves the antenna performance. The dielectric constant of dielectric resonator palette is 55 and it is fed with a 50 Ω microstrip transmission line. The aperture...
This paper describes the AC-coupled, single-sided, p-in-n silicon microstrip sensors used in the Semiconductor Tracker (SCT) of the ATLAS experiment at the CERN Large Hadron Collider (LHC). The sensor requirements, specifications and designs are discussed, together with the qualification and quality assurance procedures adopted for their production. The measured sensor performance is presented, both...
