Abstract
AbstractThis work describes the design and development of a dual‐band and dual‐polarized epsilon‐negative transmission line‐inspired antenna for wireless applications. In the proposed antenna, the implementation of curved meander lines results in antenna miniaturization; bandwidth enhancement is mainly due to the additional loading of complementary split‐ring resonator‐based mushroom resonator. Further, circular polarization radiation is obtained due to the additional loading of two‐arm Archimedean spiral resonators in the backside of the antenna forming a hybrid metamaterial structure. The proposed dual‐polarized antenna provides an overall electrical dimension of 0.17λ0 × 0.25λ0 × 0.026λ0 at the first resonating frequency of 2.49 GHz. The proposed antenna provides a fractional bandwidth of 7.22% (2.40–2.58 GHz) and 1.13% (2.62–2.65 GHz) for the first and second bands, respectively. Furthermore, the intended antenna provides maximum gain values of 1.28 dBi at 2.41 GHz and 1.94 dBi at 2.64 GHz for the first and second bands, respectively. As a result, the proposed antenna is well suited for ISM 2.4 GHz (2.4–2.484 GHz), WLAN/WiFi IEEE 802.11 b/g/n (2.4–2.48 GHz) and LTE 2500 (2.5–2.69 GHz) applications.
