چکیده
where c is the speed of light in vacuum, S = E×H is the Poynting vector, E0 and H0 are the amplitudes of the incident electric and magnetic fields, and Z0 = √ μ0/ 0 = 377 Ω (= 4π/c in Gaussian units). We also note that the small antennas are generally well described by their electric and magnetic dipole moments. So, we consider here the cases of a small linear dipole antenna, for which only its electric dipole moment is significant, and a small loop antenna, for which only its magnetic dipole moment is significant.

متن کاملA Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications
This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

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 ...
