In this letter, a tapered-slot antenna (TSA) that covers 1.5/2/2.4-GHz bands is designed for a 6-sector base station. It is shown that the TSA with desired half-power beamwidth and front-to-back (F/B) ratio at the frequency bands can be designed by loading the two pairs of slits and reflector. Results of numerical simulation show that the designed TSA radiates a sector beam with high F/B ratios over 20 dB at 1.5/2/2.4-GHz bands.
