Abstract
Metamaterial surfaces play a vital role to achieve the surface waves
suppression and in-phase reflection, in order to improve the antenna performance. In this
paper, the performance comparison of a fifth generation (5G) antenna design is analyzed
and compared with a metamaterial-based antenna for 5G communication system
applications. Metamaterial surface is utilized as a reflector due to its in-phase reflection
characteristic and high-impedance nature to improve the gain of an antenna. As
conventional conducting ground plane does not give enough surface waves suppression
which affects the antenna performance in terms of efficiency and gain etc. These factors
are well considered in this work and improved by using the metamaterial surface. The
radiating element of the proposed metamaterial based antenna is made up of copper
material which is backed by the substrate, i.e., Rogers-4003 with a standard thickness,
loss tangent and a relative permittivity of 1.524 mm, 0.0027 and 3.55, correspondingly.
The proposed antenna with and without metamaterial surface operates at the central
frequency of 3.32 GHz and 3.60 GHz, correspondingly. The traditional antenna yields a
boresight gain of 2.76 dB which is further improved to 6.26 dB, using the metamaterial
surface. The radiation efficiency of the proposed metamaterial-based 5G antenna is above
85% at the desired central frequency.
