ANN Model Optimization Hilbert Curve Fractal Antenna for Multiband Operation

Asymmetric coplanar strip(ACS)-fed with Hilbert curve fractal antenna is proposed for multiband wireless application. ACS-fed can be used to act as quarter wave transformer for impedance matching. Hilbert curve fractal antenna is used to achieve low frequency resonant, which is capable for antenna miniaturization. The proposed antenna yields multiband at 1.3080 GHz, 2.2880 GHz, 3.1350 GHz and GHz, which is suitable for LTE, Wi-Max and WLAN applications. The desired radiation characteristics is acquired in both E-plane and H-plane radiation patterns. The frequency response of the proposed antenna has been verified by an equivalent circuit analysis, which is assessed by ADS software. The optimized dimensions of the antenna have been obtained by ANN using MATLAB.
