Abstract
This paper presents the design of wideband strip helical antenna for 5G Application. The strip helical antenna is designed for 5G and wideband applications that provide a wide bandwidth and circular polarization. The helical antenna is planned on at 5.8 GHz frequency by using Teflon material. The new designed strip is printed on a substrate then rolled into a helix shape to achieve circular polarization without an impedance matching and that the proposed antenna can be used for potential applications in wideband wireless communication. A wideband bandwidth of 2.41 GHz with a resonant frequency at 5.8 GHz is achieved by the helical antenna on the Teflon substrate. The presented antenna on Teflon substrate has achieved a gain of 11.2 dB. The antenna design parameters and the simulated results are achieved using the commercial software CST. The proposed antenna can be used for various wireless applications such as Wideband, Ultra wideband, 5G and wireless Applications.
Highlights
Helical antenna or helix has a long history and have attracted various study and development for more than 60 years since its first invention [1]
The voltage standing wave ratio (VSWR) which was obtained from the simulation is about 1.52 and achieved the bandwidth of 2.4 GHz
The gain could be affected by the input impedance matching and it could be due to the crucial design parameter towards maximizing the gain of helical antenna such as its length [31]
Summary
Helical antenna or helix has a long history and have attracted various study and development for more than 60 years since its first invention [1]. The radiation behavior of the helix antenna varies according to the design structure. The antenna performances can be different in terms of polarizations and radiation pattern [3, 4]. A helical antenna consists of a conductor wound into a helical shape and connected to a ground plane [5]. Based on the helical antenna structure, it can provide a wide bandwidth with circular polarization characteristics as presented in [6,7,8,9,10,11,12,13,14,15]
