Sensors are often mounted on cylindrical shells for searching underwater objects. The sensors are contanminated by the noise generated by vibrations of the shell and their radiation. This paper investigates the noise of sensors induced by the vibrations and their radiation. The vibrations taken into account the fluid-loading effect are analysed using Waveguide Finite Element and Boundary Element Method...
A circular multiband fractal antenna is presented in this paper for multiband wireless applications. Sierpinski Gasket approach is used to make circular fractals of scaled dimensions. The fractal antenna has the multiband operation due to the self-similar property in fractal geometry. Fractal geometry leads to improved bandwidth, radiation efficiency and reduced size. The proposed antenna resonant...
The objective of this paper is designed and simulated with the using of inset feeding technique Micro strip patch antenna with four element array. The array antenna consists of four square patch antenna elements fabricated on RT/duroid 5880 substrate. The proposed antenna is designed on a relative permittivity of 2.2 RT/duroid5880 substrate and 0.25 mm thickness with an inverted U slot. It is transformed...
In this paper, a micro strip low pass filter has been designed having circular shaped defects on ground structure (DGS). For obtaining the proposed defected ground structure, two circular shaped defected ground structure are connected by slot in the ground plane and three such defects are used for obtaining the design. The cut-off frequency of the designed filter is 1.6 GHz which is useful for the...
This paper presents a study on simplest printed antenna for various ultra-wideband (UWB) based applications. The gap between height of ground plane and lower edge of patch along width is varied to observe the magnitude of S11 in the UWB frequency range for the appropriate antenna dimensions. The proposed antenna exhibits a 10 dB impedance bandwidth from 3.1 to 10.5 GHz, which constitutes about 108...
In this paper, frequency reconfigurable antenna array is presented. Reconfigurability is achieved by using a pin diode as a switch in DGS (Defected Ground Structure) antenna. An antenna array without DGS is acting as reference antenna. Further array is designed with DGS using pin diode. Both of the designs were simulated using CST and they have operating frequency of 2.62GHz, 2.94GHz and 2.52GHz....
Biomedical telemetry permits the measurement of physiological signals at a distance, through either wired or wireless communication technologies. Physiological signals are obtained by means of appropriate transducers, post-processed, and eventually transmitted to exterior monitoring/control equipment. One of the latest developments of bio medical telemetry is in the field of implantable medical devices...
Impedance of an antenna largely affects the performance of the system. ANN is trained to provide input impedance of a micro strip patch antenna since the impedance computation mathematically requires lot of parameters and is a rigorous task. Training is done through Bayesian Regularization (BR), Levenberg Mar quart (LM) as well as Scaled Conjugate Gradient (SCG) algorithms and the results are then...
Data collection for near-field microwave imaging imposes great challenges on engineering application. Long scanning time will make the phase of near-field echoes unstable, which makes the generated image unfocused. This paper presents a new planar scanning near-field two-dimensional synthetic aperture microwave imaging technique based on compressed sensing (CS), which transfers the load of signal...
Microwave heating can widely be seen in industrial application. A new method for microwave heating numerical calculation and simulation is proposed in this paper, which coupling with Fourier equation and Maxwell's equation. The method use FDTD method to solve Maxwell's equation and Euler method to get differencing heat transfer equation. The numerical analysis results show that the temperature and...
Being Familiar with the concept of Maximum Power transfer theorem, same concept is applicable to RFID tag antenna and chip. Achieving Impedance match between the Tag antenna and chip is critically important as the overall performance of RFID system dependence on it. The paper discusses about the various techniques adopted for Impedance matching in RFID Tag by varying few parameters of designed antenna.
In this paper we have proposed an antenna having a U-shape monopole micro strip feeding with defected ground surface which can efficiently work in UWB spectrum. The proposed antenna has a return loss value lower than-10dB over the entire ultra wideband (UWB). Proposed antenna has desired value of voltage standing wave ratio (VSWR<2) between the frequency band of 3.192 GHz to 11.241 GHz. It is designed...
