A Compact, Tri-Band and 9-Shape Reconfigurable Antenna for WiFi, WiMAX and WLAN Applications

Abstract

This paper introduces a novel 9-shaped multiband frequency reconfigurable monopole antenna for wireless applications, using 1.6 mm thicker FR4 substrate and a truncated metallic ground surface. The designed antenna performs in single and dual frequency modes depending on switching states. The antenna works in a single band (WiMAX at 3.5 GHz) when the switch is in the OFF state. The dual band frequency mode (Wi-Fi at 2.45 GHz and WLAN at 5.2 GHz) is obtained when the switch is turned ON. The directivities are: 2.13 dBi, 2.77 dBi and 3.99 dBi and efficiencies: 86%, 93.5% and 84.4% are attained at frequencies 2.45 GHz, 3.5 GHz and 5.2 GHz respectively. The proposed antenna has VSWR< 1.5 for all the three frequencies. The scattering and far-field parameters of the designed antenna are analyzed using computer simulation technology CST 2014. The performance of the proposed antenna is analyzed on the basis of VSWR, efficiency, gain, radiation pattern and return loss.

Design and Experimental Analysis of Multiband Frequency Reconfigurable Antenna for 5G and Sub-6 GHz Wireless Communication

“…In terms of size, the proposed antenna is more compact than other antennas reported in [32][33][34][35][36][37][38]. The proposed antenna has impedance bandwidth ranges 190-1400 MHz which offers larger bandwidth than antennas designed in [32,33,[35][36][37][38][39] and has better gain than the work reported in [32][33][34]36,37,39]. The most prominent distinction, as compared to other candidate antennas, is the ability of proposed antenna to operate on nine different frequency bands, which are more than the number of bands achieved in all reported In terms of size, the proposed antenna is more compact than other antennas reported in [32][33][34][35][36][37][38].…”

Reconfigurable circular patch MIMO antenna for 5G (sub‐6 GHz) and WLAN applications

“…With a frequency range of 0.43–5 GHz, a reconfigurable antenna with a dimension of 60 × 100 mm 2 was exhibited. In Ali Shah et al, 34 there were discussions regarding a reconfigurable antenna with proximity couple feeding for WLAN and sub‐6 GHz applications. Two substrates (separated by air) with four PIN diodes made up the antenna.…”

Design of dual band slotted reconfigurable antenna using electronic switching circuit

“…The bluetooth, WiMAX and WLAN band frequencies range from 2.36 GHz to 2.5 GHz, 3.51 GHz to 3.79 GHz and 5.47 GHz to 5.98 GHz, respectively. Another study [23], has demonstrated a reconfigurable antenna design with a triple state with dual wide operating bands supporting the WLAN applications. The switching capability was achieved by using a PIN diode with triple state functionality that enabled the antenna to provide three difference frequency responses.…”
