摘要

A nanocomposite-filled slot antenna is designed to improve the radiation of a triple band radiator which consists of two rigid radiating elements united to the central strip of a coplanar waveguide (CPW) antenna. The longer strip resonates at the lower resonance frequency and the shorter strip—at the middle resonance frequency. The upper band of the triple band radiator is formed by the L slot on the left CPW ground. The gain and bandwidth of the proposed radiator are improved by a nanocomposite-filled slot. A better cross polarization of the radiator is achieved by decreasing the coupling of rigid radiating elements by spacing them properly. The compact structure is attained by uniting the radiating strips to the 5.00 mm wide signal-generating strip. The proposed radiator bandwidth is within 3.08–3.80 GHz for the lower band, 4.57–5.56 GHz for the middle band and 5.95–7.51 GHz for the upper band, which covers WLAN, WiMAX, 5G and Wi-Fi with an enhanced gain. The proposed radiator is suitable for practical wireless applications due its good radiation characteristics.
