Theoretical Study of Radiation Characteristics of Short Dipole Antenna
نویسنده
چکیده
This paper theoretically examines the key dipole antenna parameters that define their performances in terms of current distribution, radiation resistance, input impedance, radiation efficiency, size, bandwidth, quality factor and directivity. We have investigated how these parameters are related to each other and also how variation of one alters the overall performance of the antenna. Bandwidth, Input Impedance, Quality factor, Radiation Resistance

Design, Simulation and implementation of active dual-band dipole antenna using a series stub
In this paper, a new method for designing an active dual-band dipole antenna is proposed. The operating frequencies of the proposed antenna are 150 and 450 MHz that are usually used in military applications. Using a series stub is the main idea in the proposed dual-band antenna, where it makes an independent resonance frequency higher than the main resonance frequency of a conventional dipole. ...

This theoretical study examines the characteristics of a surface wave driven plasma monopole antenna using finite difference time domain method (FDTD) as well as commercial full wave simulator. The results show that the full wave simulator can be considered as an acceptable tool in simulation of a plasma antenna. Input impedance, radiation pattern, gain, efficiency and radar cross section of pl...

We have modeled and simulate asymmetric microstrip folded dipole antenna on substrate materials and study the antenna performances. The conventional wire dipole antenna configurations are converted into corresponding microstrip version. The complementary nature of parallel coplanar strip line and waveguide models have been used to model the dipole antenna. The transmission line parameters namel...
متن کاملAnomalously small retardation of bound (force) electromagnetic fields in antenna near zone
At fundamental level this work uncovers the actually incomplete knowledge of the energy transmission and propagation related to bound (force) electromagnetic (EM) fields. To deal with this problem, we present an experimental approach to a separate study of propagation characteristics of bound and radiation EM fields produced by antennas in a vacuum. A series of our recent experiments continues ...
