Coplanar wave guide fed fork shaped frequency reconfigurable antenna for LTE, WI-FI and WLAN applications

Abstract

A coplanar wave guide fed fork shaped antenna is designed with reconfigurability for switching between the application bands of LTE, Wi-Fi and WLAN. A novel closed hut shaped ground plane structure is used in the construction of the antenna model for good impedance matching with the feed line. The basic structure of the antenna model is working in the UWB range from 3.1 to 10.6 GHz. The adjacent strips of the monopole consisting of the slots for the placement of PIN diodes. The switching operation of the diodes providing frequency reconfigurability nature in the antenna between LTE (2.1-2.2 GHz), Wi-Fi (2.4 to 2.7 GHz) and WLAN (5.6-5.8 GHz) bands. Antenna is providing peak realized gain of 4.5 dB and efficiency more than 70% in the operating bands. The prototyped antenna is providing excellent measurement results in correlation with simulation results obtained from CST Microwave Studio.

A Compact CPW-Fed Textile-Substrate-Based Half-Circula Spike Monopole Antenna

“…Reconfigurable antennas with pattern, polarization, frequency and hybrid reconfigurability are achieved in few designs by engineers with PIN (personal identification numbers), varactor diodes and liquid crystal compound loading [11]. Square slot ring resonator-based notch band antennas have been designed by scientists for ultra-wideband and medical communication applications [12].…”

A Coplanar Waveguide Fed Asymmetric Ground Frequency Reconfigurable Antenna

“…The reconfigurable antenna usually equipped with switches that are controlled by DC bias signals. By toggling these switches in on and off states, the antenna will be reconfigured to support a dedicated set of operating frequencies [15]. The reconfigurable antennas consist of three types of configurations like frequency reconfigurability, polarisation reconfigurability and hybrid reconfigurability (both frequency and polarisation reconfigurability) [16].…”
