چکیده

In this note we consider some of radiating dipole antenna as related to content of the radiated waveform. For the design-parameters for a pulsethe high-frequency and low-frequency the high-frequency portion the use of a biconfcal wave launcher is discussed, The low-frequency content depends on such parameters as generator voltage and capacitance and the capacitance and mean charge separation distance of the antenna. The mean charge separation distance of the antenna is shown to be the same as its equivalent height. Finally, a technique is discussed for achieving a large antenna capacitance by making the dipole structure have an electricallylarge radius while still maintaining a sparse mechanical structure. This technique involves the use of wires (or strips, etc.) to approximate a conducting circular cylinder.

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. ...

A New Design of Log-Periodic Dipole Array (LPDA) Antenna

This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...

Nonlinear Analysis of Nonlinearly Loaded Dipole Antenna in the Frequency Domain Using Fuzzy Inference

In this paper, inference model is proposed so as to analyze nonlinearly loaded dipole antenna. In modeling process, linear and nonlinear behavior of the problem is saved as simple and unchanged membership functions and the effect of incident wave on the induced voltage at different harmonies are then extracted easily. Consequently the model achieved is more efficient than previous studies using...

Antenna Theory -A comparative study

this article presents an overview of the recent Frequency dependent and Frequency independent antenna theory. An antenna is defined by Webster’s Dictionary as “a usually metallic device (as a rod or wire) for radiating (transmitting) or receiving radio waves or EM wave.” The IEEE Standard Definitions of Terms for Antennas (IEEE Std 145–1983) defines the antenna as “a means for radiating or rece...
