Abstract

The article proposes a novel design for a high gain dual-band millimeter wave (mm-wave) antenna at 26.5 and 36.5 GHz frequency bands using flexible substrate and Co-planar waveguide (CPW) technology. The CPW is able to provide 1.2 GHz bandwidth at 26.5 GHz center frequency and 3 GHz bandwidth at 36.5 GHz with 7.2 and 9.7 dBi gain, respectively. The antenna is composed of a square patch and L-shape slots that are placed symmetrically with distances less than λ/4 (upper band) and the antenna has total dimensions of 16 mm×19 mm. The simulated antenna results are presented in terms of radiation patterns and return loss, and maximum gain as a function of frequency. The performance at millimeter wave and structure flexibility capability are demonstrated that the antenna has potential to implement in the upcoming 5G communication networks.
