CPW-Fed Transparent Antenna for Extended Ultrawideband Applications

In this article, a compact design of the monopole antenna is proposed for the super‐wideband application (SWB). The extremely wide frequency bandwidth is achieved by deploying a topology based on trapezoid shape radiator, triangular tapered feed line, and semicircular ground. The antenna shows resonance from 1.42 GHz to more than 90 GHz with a bandwidth ratio of 63.30:1, VSWR ≤2 and with S11 ≤ −10 dB. The electrical dimension of the monopole antenna is 0.16λc × 0.27λc where the wavelength λc is with respect to the lowest cut‐off frequency. The designed monopole antenna is fabricated on the F4B substrate. The prototype is experimentally validated for ultrawideband and SWB application. The experimental and simulated results are in good agreement and the designed antenna shows better performance of a wideband operation, compact electrical dimension, and high bandwidth dimension ratio over existing reported structures. The proposed antenna can be used for multiple bands such are ISM, Wi‐Fi, WLAN, WiMAX, C, S, X, K, and Ku bands.

“…Silver combined with tin oxide which is available in two different variants namely AgHT‐4 and AGHT‐8 has emerged as a good alternative for indium owing to its transparent property and the acceptable value of conductivity . Various nonflexible transparent antennas are proposed by researchers for dual‐band operation and wideband applications . Flexible antennas owing to its ease of integration in nonplanar surfaces along with its wide range of applications in flexible electronics and wearable devices have attracted a lot of researchers to work in this domain.…”

et al. 2020

A transparent flexible co‐planar waveguide fed patch antenna using polyethylene terephthalate substrate is presented. The wideband high gain antenna having an overall dimension of 0.48λ × 0.64λ at the center frequency of 4.28 GHz is fabricated using a transparent sheet made up of Silver Tin Oxide (AgHT‐8). The performance of the proposed antenna is compared with four other nontransparent nonflexible and semitransparent flexible antennas. For the engineered design, patch geometry and feeding mechanism are kept constant whereas the substrate and patch materials are varied. Simulations are carried out using finite element method‐based full wave high‐frequency structure simulator after which the antennas are fabricated and tested. The proposed flexible transparent antenna has bandwidth in order of 40%, ranging from 3.89 to 5.9 GHz, with a notable gain over 3 dBi and efficiency greater than 80% for the entire frequency band. The bending conditions are also tested for the flexible transparent antenna which showed decent performance for sub‐6 GHz 5G and WLAN applications.

2017

This letter investigates a circular base loaded modified rectangular monopole radiator. Two main aims of presented research article are: (a) to achieve super wide bandwidth with the help of circular base loaded rectangular monopole, tapered microstrip line feed and elliptical ground plane; (b) to increase bandwidth dimension ratio (BDR) with the help of modification in rectangular monopole. To authenticate the proposed radiator, prototype has been fabricated and measured. Experimental outcome shows that the proposed radiator operates over the frequency range from 0.96 to 13.98 GHz (VSWR < 2) with a bandwidth ratio of 14.56:1 and having fractional bandwidth of 174.29%. Bandwidth dimension ratio for proposed radiator is 7468.51. Time domain analysis has also been performed to support the applicability of proposed radiator in super wideband applications.
