Abstract
The new radiator incorporated with nanocomposites improve radiation characteristics of nonagon shaped antenna. The design comprise two nanocomposite materials loaded in slots that separately enhance lower and upper band radiation. The CPW antenna consists of nonagon shaped ring with heptagon radiating element that consists of inverted U and rigid shaped slots. The longer slot has been deliberately chosen to accommodate mid-frequency of two resonance frequencies and shorter slot isolates surface current distributed along radiating patch, left and right side. The Poly (3, 4 ethyelene dioxythiophene): Polystyrene Sulfonate-Silver nanowire (PEDOT:PSS-AgNW) nanocomposite filled in shorter slot improves gain, bandwidth and return loss of upper band, magnetite - Polyaniline (Fe3O4-PANI) filled in longer slot enhance lower band. The measured result proved to improve bandwidth, gain, radiation efficiency and polarization of lower, upper band. The flexible attributes of radiator studied extensively by wearable application by placing them on wrist and jeans. The fabricated antenna produce a bandwidth of 2.12–3.29 GHz in lower band, 4.51–6.00 GHz in upper band for 2.40/5.20/5.80 GHz WLAN, 2.50/5.50 GHz WiMAX, 2.40/4.90/5.20/5.50/5.80 GHz WiFi, 5G SUB-6 GHz and ISM bands.
