One of the problems that correspond to the small dimension of an antenna is the bandwidth. In order to overcome the problem from small linear and multiple antenna array systems, the investigation of the antenna elements is needed. The design of planar antennas is to achieve an antenna that is able to match various demands in applications where size, cost, performance, and aerodynamic profiles are very important considerations, a low-profile antenna such as a small. The antenna performance on scattering parameters S11, gain, return loss and impedance input are investigated at obtaining wideband antennas by adjusting antenna design parameters. The substrate thickness needs to be adjusted to 0.813 mm, and the element length at 2 mm and 0.75 mm. The calculation of VSWR, gain, and the radiation pattern is presented using MoM-based WIPL-D. The antenna element when x2 is 2mm in the frequency range 4 GHz-8 GHz, which this antenna works best on element dimension x2= 1.5mm when the frequency resonance 4.86 GHz and VSWR value is 1. The main advantages of this antenna are the dimension and simple design. © Published under licence by IOP Publishing Ltd.
