A Novel Eye-shaped Monopole Antenna for Wideband and 5G Applications

This paper presents a compact dual-band monopole antenna printed on the low-cost FR4 substrate for multi wireless communication applications. The novel antenna consists of an eye-shaped patch and a semicircular shaped slot on the half elliptical ground plane. The antenna's measurement results include multiband frequencies such as S, C, X, Ku, K, and Ka-band, which covers the bandwidth requirements of WiMAX, WLAN, satellite TV, and 5G applications at the lower and upper-frequency band. The dimension of the antenna is (26 x 20 x 1.6) mm(3) at the minimum frequency of 3.15 GHz. The proposed configuration operates at 3.55 and 19.95 GHz with a bandwidth of about 28.17% (3.15-4.15 GHz) and 147.37% (5.25-34.65 GHz), respectively, for the simulation part. The measured bandwidth (-10 dB) for S11 in the lower and upper band is about 49.71% (2.688-4.506 GHz) and 152.01% (4.933-35.861 GHz) at a centre frequency of 3.657 and 20.346 GHz, respectively. The proposed antenna has a stability of the radiation characteristics, suitable gain, and good impedance across the operating bandwidth of the dual-band antenna.
