Abstract :
This paper presents the enhancement of FB ratio by optimizing several types of reflector shape which are placed on the back of a dipole antenna for the sector antenna. By optimizing the size of each reflector shape, the FB ratio of dipole antenna is increased by more than 20dB. Comparing each shape for the same width of reflector, a dual box reflector has the best FB ratio of more than 30dB
