Engineering and Technology Journal, 2016, Volume 34, Issue 6, Pages 1194-1206

In this paper, the planar dual-band monopole antenna is presented for Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) applications. The design of the proposed antenna is based on Peano fractal curve and meander line structures. The antenna operates in 1.71 GHz to 2.01 GHz in the desired LTE frequency band and 5.0 GHz to 5.5GHz band (IEEE 802.11a band). The frequency band 1.71 - 2.01 GHz is already available as a study of the current plan according to UMTS and LTE systems (the band no.4). The antenna has been fixed on a substrate boardArlon with εr= 2.33 and thickness of 0.9 mm. Simulation results shows that the proposed antenna has promising radiation characteristics and a reasonable gain of 2.155 dBi at the lower band and 4.772 dBi at the upper band. The simulation and evaluation of antenna performance werecarried out using Microwave Studio Suite of Computer Simulation Technology CST.

In this paper, the fractal concept has been used in the linear array antenna
design to obtain multiband operation. The fractal linear array antenna has been
designed at a frequency of 750 MHz with equal spacing and uniform amplitude
distribution of the elements array. 1st iteration quadratic Koch curve dipole fractal
element is used in design of the array. The proposed antenna array design, analysis
and characterization had been performed using the Method of Moment (MoM)
technique. The radiation pattern, side lobe level (SLL), directivity (D), and input
impedance of the proposed antenna are described and simulated using 4NEC2
software package and MATLAB programming language version 7.6.
