Abstract
We presented the characteristics of the front-to-back (FB) ratio by using a dipole antenna backed by several types of reflector shapes. We simulated the radiation pattern and FB ratio of a dipole antenna by changing the size of rectangular reflector, dual reflector, and boxing reflector. There is an optimum size for each shape of reflector, and FB ratio of the dipole antenna is increased by more than 20 dB. Comparing each shape of the reflector when the width is constant, using a boxing reflector has the best FB ratio of a dipole antenna of about 29 dB.
