bandwidth enhancement of cylindrical triangular microstrip antenna using a stacked technique

This paper presents a new design of a conformal microstrip antenna operating in a dual-band for several applications including wireless local area networks (wlan), wi-fi networks, and wireless body area networks (wban). the proposed design was achieved using the stacked patch technique on a conformal microstrip antenna. one of the patches is square-shaped and the other is triangular-shaped constructed on a cylindrical surface with a 50 mm radius using a substrate with a permittivity of 2.98. the proposed design can be called a stacked square-shaped triangular cylindrical microstrip antenna. the operating resonant frequencies have been set at 623 and 795 ghz. for the standard antenna, the bandwidths of dual-band are equal to 0.65 % and 0.92 %. by adding an air gap between the ground plane and substrate, bandwidths are enhanced to 6.15 % and 3.07 %, and then increasing the substrates’ thickness leads to more improvement of the percentage of bandwidth to 40.2 % and 24.12 %. the finite-difference in time domain (fdtd) method is used to design and analyze the proposed antenna.
