Abstract
There is a need of low profile and multiband antennas in various fields of wireless communication lower band applications. Suitable gain with higher data rates for future communication modules in compact range is most challenging for design engineers. In this paper, Log Periodic Dipole Array antenna was designed and proposed for frequency range from 900 MHz to 2.6 GHz, operating frequency for the proposed antenna is 0.9 GHz (GSM), 2.1 GHz (PCS) and 2.4 GHz Industry standard Medical (ISM) and Wi-Fi applications. The modelled antenna constructed on FR4 substrate with height of 1.6mm, and analysed with electromagnetic simulation software like Magus, CST (Computer Simulation Technology) and HFSS (High Frequency structure simulator) tools. The proposed antenna has advantages like wideband, simple design, antenna results indicate the reflection coefficient value below -10dB for whole band from 900 MHz to 2600 MHz. The proposed antenna showing overall gain of 6 dB. Several antenna parameters are evaluated in Finite Element Method (FEM) and Finite Difference Time Domain (FDTD) and provided comparative analysis in this work.
