Abstract

This paper proposes a new metasurface to improve gain for dipole antenna. The antenna includes two sets of two elements (1 x 2), the integrated J shaped baluns, five metasurface cells (each metasurface cell consists of 5 periodic metallic plates printed on a thin low-cost FR4 substrate) for four antenna elements and the antenna is supplied by two T-junction power dividers. The metasurface is designed to operate as reflection surface. The antenna is designed based on RT5880 and witnesses an overall size of 140 x 37 x 35.075 mm3 (2.7λ x 0.71λ x 0.67λ at 5.8 GHz), an isolation of approximately 28 dB, a peak gain of 9.5 dBi, and a radiation efficiency of 84%
