Bandwidth enhancement of cylindrical triangular microstrip antenna using a stacked technique

This paper presents a new design of conformal microstrip antenna operating in dual-band for several applications including Wireless Local Area Networks (WLAN), Wi-Fi networks, and Body (WBAN). The proposed was achieved using the stacked patch technique on antenna. One patches is square-shaped other triangular-shaped constructed cylindrical surface with 50 mm radius substrate permittivity 2.98. can be called triangular resonant frequencies have been set at 623 795 GHz. For standard antenna, bandwidths are equal to 0.65 % 0.92 %. By adding an air gap between ground plane substrate, enhanced 6.15 3.07 %, then increasing substrates' thickness leads more improvement percentage bandwidth 40.2 24.12 Finite-Difference Time Domain (FDTD) method used analyze
