SIMULATING RADIATED FIELD COMPONENTS PRODUCED BY A SHORT CURRENT ELEMENT FOR ANTENNAE DESIGN APPLICATIONS

Abstract

Correlation of parameters of an antennae with its electrical properties is fundamental to the design of transmitting or receiving aerials. Antennae performance depends largely on the radiation pattern of the electric and magnetic field components. To design an efficient antennae,it is basically essential to understand the mechanisms involved in the determination of radiated electric and magnetic field components over a range of antennae dimensions, wavelenght and frequency of signal. In this paper,mathematical models were developed for radiated field in the simplest possible antennae,a short dipole in free space. The models are simulated on computer,using the turbo C++ language for general applications by design engineers.
