Sub-6GHz Novel C-Shaped Antenna for 5G Application

A novel C-shaped antenna design resonating at Sub-6GHz band for 5G application is reported in this work. The radiator is etched on FR4 dielectric
$({\varepsilon}_{\mathbf{r}}=4.3)$
having height of 1.6 mm. On the other side of dielectric, the mirror image of the radiator is etched on the ground plane which is an inverted ‘C’. Conventional quarter-wave transformer is designed to match the antenna impedance to 500. The entire dimension of proposed design which is simulated in CST Microwave Studio is 34 ×32 × 1.6 mm

that achieves the gain and bandwidth of 3.4 dB and 500 MHz at the resonating frequency of 3.5 GHz lying in mid-band frequency range allocated for fifth-generation.
