ABSTRACT
This
paper investigates the performance characteristics of broadside and end-fire
linear arrays of half-wave dipole antennas for radio broadcasting. Six FM radio
stations from the six geo-political zones of Nigeria are selected as candidates
for the analysis, each at their operating frequencies. The results of the array
factor algorithm used for the analysis of all the FM radio stations show that,
for the best directivity and minimum relative side lobe levels, the maximum
inter-element separation for end-fire configuration is 0.42λ and 0.45λ for a
broadside arrangement of dipoles. This amounts to a reduction of 46.7% in the
size of the antenna structure for an 8-elements linear array of dipoles
arranged in end-fire configuration.
Keywords: Dipole antenna, Broadside configuration (BRC), End-fire configuration (EFC), array factor (AF)
