Abstract

This paper proposes the dual-band S-patch antenna with gain enhancement by using the planar array configuration and dielectric superstrate. The design of the proposed antenna is focused on the base station antenna in the 5G frequency bands n41 (2.6 GHz) and n78 (3.5 GHz). The dual-band S-patch antenna is arranged in the
2 × 6 elements planar array antenna and the FR4 dielectric superstrate is on the top of the array. The simulated results indicated that the operating frequency of 2.55–2.65 GHz and 3.46–3.61 GHz with uni-directional radiation pattern. The antenna gain can be improved with 18.70 dBi at 2.6 GHz and 19.30 dBi at 3.5 GHz. The prototype antenna is fabricated and the measured results are in good agreement. With the simple design of the proposed antenna, it would be useful for the installation of the base station antenna.
