چکیده
In this paper, we propose two electrical models of carpet and gasket Sierpenski patch antenna. In our approach, we replace the antenna structure by its equivalent rectangular patch. Then, we build the electrical model in which we extract the resonant circuit RLC parameters. Return losses of the models are compared to physical patch for frequency band [1GHz, 3GHz]. Simulation results given by our approach, show that the antenna and its model have the same resonant frequency at 2.45GHz but with a little difference in Bandwidth.

Design and Miniaturization of a Novel Fractal Microstrip Antenna for UWB Applications
A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
متن کاملDesign and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements
A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...
