today, we see that despite the plans and decisions made about the historical fabric, the people are very faintly seen and conservation the historic fabric of urban is one of the main concerns management urban in the absence of efficient management and lack of attention to the needs of local people, the historical fabric urban is destroyed. in this article are examined ways other than physical m...

Antenna Miniaturization Using Fractals Richa Garg, AP ECE Deptt., [email protected], J.C.D.C.O.E., Sirsa ABSTRACTThe use of fractal geometry in designing antenna has been a resent topic of interest. Fractal shape has their own unique characteristics that the improved antenna performance can be achieved without degrading the antenna properties. Modern telecommunication system requires antenn...

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

This study designed and analyzed an artificial magnetic conductor (AMC)-based fabric antenna for body-centric communication. The was made of felt had a loss tangent 0.044 relative permittivity 1.3. proposed built to function in the frequency band centered at 2.45 GHz, widely used wireless communication devices. antenna’s performance evaluated using electromagnetic simulation software CST MWS. A...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antenna’s truncated ground-plane incorporates a central notch. This modification significantly improves the antenna’s impedance bandwidth by 118% over an ultra-wideband frequency range. T...
