Abstract:

The thesis deals with the design and implementation of broadband and narrowband antennas and their applications in practical environment. In this thesis, a new concept for designing the UWB antenna is proposed based on the CRLH metamaterials and this UWB antenna covers a frequency range from 2.45 GHz to 11.6 GHz. Based on the design of the UWB antenna, another antenna is developed that can cover a very wide bandwidth i.e from 0.66 GHz to 120 GHz. This antenna can not only be used for UWB applications but also for other communication systems working below the UWB spectrum such as GSM, GPS, PCS

Abstract:

This effort is focused on the design, calibration, and implementation of a high temperature heat flux sensor for thermal systems research and testing. The High Temperature Heat Flux Sensor (HTHFS) was designed to survive in the harsh thermal environments typically encountered in hypersonic flight, combustion and propulsion research, and large-scale fire testing. The sensor is capable of continuous use at temperatures up to 1000 â ¦C. Two methods for steady-state calibration of the HTHFS at elevated temperatures have been developed as a result of this research. The first method employs a water-

This thesis is part of a project, Working on Venus, funded by the Knut and Alice Wallenberg Foundation (one of the largest Swedish funders of research) and developed by KTH in collaboration with Linkӧping University. The goal of this project is to create a lander able to investigate the planet Venus and to work under extreme conditions, i.e. it has to be able to withstand at high levels of radiation and high temperatures such as that of Venus surface (that is about 460 °C) without integrating a dedicated bulky cooling system to reduce the overall weight and volume of the system.

Abstract:

Heat flux gages are important in applications where measurement of the transfer of energy is more important than measurement of the temperature itself. There is a need for a heat flux sensor that can perform reliably for long periods of time in high temperature and high heat flux environment. The primary objective is to design and build a heat flux sensor that is capable of operating for extended periods of time in a high heat flux and high temperature environment. A High Temperature Heat Flux Sensor (HTHFS) was made by connecting 10 brass and steel thermocouple junctions in a thermopile cir

Abstract:

Technical challenges for developing micro sensors for Ultra High Temperature and turbine applications lie in that the sensors have to survive extremely harsh working conditions that exist when converting fuel to energy. These conditions include high temperatures (500-1500°C), elevated pressures (200-400 psi), pressure oscillations, corrosive environments (oxidizing conditions, gaseous alkali, and water vapors), surface coating or fouling, and high particulate loading. Several technologies are currently underdeveloped for measuring these parameters in turbine engines. One of them is an opti

Abstract:

Optical current sensors (OCSs) are initially developed to measure relatively large current over a wide range of frequency band. They are also used as protective devices in the event a fault occurs due to a short circuit, in the power generation and distribution industries. The basic principal used in OCS is the Faraday effect. When a light guiding faraday medium is placed in a magnetic field which is produced by the current flowing in the conductor around the magnetic core, the plane of polarization of the linearly polarized light is rotated. The angle of rotation is proportional to the magnet

碩士<br>長庚大學<br>電子工程學系<br>105<br>Magnetic field sensors have been assisting human kinds for a long period of time in various issues like nearly unlimited computer memory, flux-gate sensors for military applications, angle and crack detectors. In this thesis, the main focus is to design a BiNMOS magnetic sensor with low magnetic field but with better sensitivity. A readout circuit design has been designed to use this sensor for detecting angle applications. The fabricated chip area is 0.949*1.003〖mm〗^2 and power consumption is 1.16mW. The sensitivity of the magnetic sensor is 5.95% with the appli

碩士<br>國立雲林科技大學<br>電子工程系<br>103<br>The advanced integrated circuit (IC) fabrication process causes growing power density due to higher transistor density and area miniaturization. This phenomenon reflects to chips, the first impact is the increasing temperature, then chip operation becomes unstable. therefore, embeds a temperature sensing circuit to auto-adjust power dissipation has become an important issue, there are more embedded temperature sensors to sense temperature instantly. To keep chip area be small, avoid process effect and be easily embedded on SoC. All- Digital ring oscillator cir

The architecture of oversampled analog/digital interface is a first order continuous-time ΔΣ converter, which is based on oversampling, feedback and filtering of the quantization error. In order to verify the Oversampled analog/digital interface circuit, a PTAT sensor is developed with CMOS parasitic substrate PNP transistor. Furthermore, with a bandgap reference circuit as a

In this paper, the design of sensors is mainly to sense the displacement. FBG is easily to have misjudgements in sensor value due to the influence of the external environment temperature, so we designed temperature insensitive to make the measured value is more correct. The method of reaching temperature insensitive, the FBG with original single period has been designed

On the other hand, the increasing circuit operating speed also enhances the power in a chip. However, since chip temperature increases along with its operating speed, the increasing temperature may result in malfunction or even physical damage in system chips. To avoid this problem, chip would need temperature sensor to monitor its temperature. Studies show that temperature sensors can be categorized into analog sensors and digital sensors. Since anal

In this thesis, the details of the design, fabrication, and characterization of an optical, integrated hydrogen gas and temperature sensor are explored. The hydrogen sensor is implemented by coating a ridge waveguide with a thin layer of palladium and shows very good response time and detection response for hydrogen concentrations ranging from 0.5-4%, both of which compare very favourably to similar existing technologies. Multiple film thicknesses were tested and it was found that thinner films give a faster response time at the expense of a reduced detection response. The temperature sensor i
