ANALYSIS OF DIPOLE ANTENNA RADIATION PATTERNS USING LOW FREQUENCY MODEL

Abstract

Antennas are an extremely vital element of communication systems and radar technologies. The antenna will produce radiation dispersed in space in a definite way when a signal is feed into an antenna, which called a "radiation pattern". Most pervious literatures concentrates on studying the effect of an EM filed on communication systems that have high frequency and its radiation pattern on far filed. The main aim of this paper is in order to investigate the effect of the electromagnetic EM-field in communication systems that have low frequency, and using the MATLAB software simulation in order to show this effect to describe the radiation pattern for an antenna on far field for different low frequencies due to the lack literatures that focus on this field. A dipole antenna is analyzed using the radiation pattern on far field for different low frequencies model within the frequency band of 1-5 KHz, to make the final design realizable.
