Abstract
One of the problem corresponds 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. 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, radiation pattern 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 from 2 mm to 0.05 mm. The calculation of return loss, gain, and the radiation pattern is presented using MoM-based WIPL-D. The antenna element when L2 is 2mm in the frequency range 4 GHz – 8 GHz which reaches a bandwidth of 23.4% and the resonance frequency less than the frequency of 5 GHz. When L2 changed to 0.05 the resonance frequency becomes 5 GHz and the bandwidth increased to 31.5%. Therefore, decreasing antenna element length(L2) affect the resonance frequency to the higher frequency and increase the bandwidth.
