Abstract—This paper presents a planar microstrip-fed tab monopole antenna for ultra wideband wireless communications applications. The impedance bandwidth of the antenna is improved by adding slit in one side of the monopole, introducing a tapered transition between the monopole and the feed line, and adding two-step staircase notch in the ground plane. Numerical analysis for the antenna dimens...
The enormous advancement in science and technology has led to increase in the requirements for high speed data transmission. The increase in the speed of the digital circuits as well as the density of printed circuit board will often result in more challenging signal integrity issues. One of the most important signal integrity issues is radiated emission. We analyzed the radiation in different ...
Passive UHF RFID tag consists of a microchip attached to an antenna. Proper impedance match between the antenna and the chip is crucial in RFID tag design. It directly influences RFID tag performance characteristics such as the read range. It is known that an RFID microchip is a nonlinear load whose complex impedance varies with the frequency and the input power. We investigate the effect of us...
In this paper, a complete design and analysis of the frequency selective property of an array of patches with annular rectangular slots is presented. It is observed that there is a tremendous decrease in resonance frequency as the annular rectangular slot is made on the patch and it is also seen that, with the incorporation of another annular rectangular slot, FSS is resonant at dual frequencie...
In this paper, a dual frequency resonance antenna is analysed by introducing L-shaped slot in a semi circular patch, different parametric studies have allows and the results in terms of return loss and radiation pattern are given. It is observed that various antenna parameters are obtained as a function of frequency for different value of slot length and width; it is easy to adjust the upper an...
The tunable characteristics of RF MEMS (Microelectromechanical Systems) components enable their integration with antennas providing numerous advantages such as reconfigurability in polarization, frequency, and radiation pattern [1]. Furthermore, the monolithic fabrication of these components with antennas can reduce parasitic effects, losses and costs. This paper presents two tunable frequency ...
