Dual band slotted transparent resonator for wireless local area network applications

Abstract

In this paper, a transparent dual-band antenna having a size of λ/4 × λ/4 mm 2 at the lower resonance frequency of 2.4 GHz is proposed. Antenna operates at the frequency band of 2.47 GHz and 5.32 GHz, respectively. The resonator geometry is in the form of a modified slotted split ring resonator with the extended slot line sections at the split ends. AgHT-8 conductive oxide material is used for the radiating element and ground plane of the antenna. Optically transparent borosilicate glass having a dielectric constant of 7.75 with 2 mm thickness is used as the substrate material to achieve the optical transparency. The impedance bandwidth of the proposed antenna in the lower and higher frequency bands is 8.3% (2.34 GHz-2.54 GHz) and 2. GHz), making the proposed transparent antenna suitable for dual-band WLAN applications. K E Y W O R D SAgHT-8, dual band, glass substrate, transparent conductive oxide, WLAN antennas

Flexible CPW fed transparent antenna for WLAN and sub‐6 GHz 5G applications

[21][22][23] The efficiency of transparent antennas has been improved with the help of new efficient excitation techniques starting with the enhanced soldering methodologies with the result of 20% improvement. 24 The sale of AgHT-8 as a material for its use in the antenna design has not risen much to the expected commercial level due to the low conductivity value which necessitates the antenna efficiency to be improved.…”

A hybrid multiband printed loop antenna for WLAN/WiMAX bands forapplications in MIMO systems

“…* Correspondence: amin.honarvar@pel.iaun.ac.ir Due to the small size and low cost of such systems, there has been a surge of interest [4] in printed antennas. To cover multiple bands simultaneously, various antennas including a multiple mode monopole antenna, loop, and slot antenna have been proposed [4][5][6][7][8][9][10][11][12][13][14][15]. However, classic loop antennas are typically narrow band radiators that occupy much space.…”
