“…The steering characteristic of the radiation pattern at a fixed operation frequency is also required and can be used to avoid noise source, improve security, and save energy by better directing the signal toward intended users as shown in Reference . Different switching technologies are used to obtain agility such as Micro‐Electro‐Mechanical‐Systems (MEMS) switches, varactor, and PIN diodes …”

This article presents a reconfigurable frequency and steerable beam monopole antenna based on tunable graphene pads operating in both 4G and 5G bands. The proposed antenna consists of printed CPW‐fed circular monopole shapes, with five rectangular strips added with a separation angle of 45°. These strips are connected to monopole by using graphene pads. The monopole antenna operates in the lower 5G band from 3 up to 7.8 GHz at −6 dB reflection coefficient. The antenna has an omni‐radiation pattern over the operating band without any applied bias voltage to the graphene pads. By applying the DC bias voltage, the rectangular strips are connected to the monopole and the designed antenna start to resonate from 1.8 to 8 GHz adding the 4G band frequencies. The steering of the proposed antenna beam started from −60° to 60° according to the bias of the connected graphene pads. The graphene pad exhibits a variable resistance realizing an almost short to an open circuit with and without voltage bias, respectively. The designed antenna is simulated using high frequency structure simulation (HFSS) Ansys ver. 19 and equivalent circuit model of the graphene. The antenna is fabricated using reduced graphene oxide (RGO) pads. Reflection coefficient and radiation pattern measurements as well as simulations are presented with a positive agreement between the results.

A planar printed dipole antenna with reflectors and directors, able to steer its radiation pattern in different directions, is proposed for telecommunication applications. Starting from a dual-beam printed dipole antenna achieved by combining two elementary dipoles back to back, and by loading four PIN diodes, three modes of reconfigurable radiation patterns are achieved at the frequency 2.56 GHz thanks to switches states. A prototype of the structure was realized and characterized; an efficiency of 75% is obtained. Simulation and measured results of the results are presented and discussed.
