Abstract

A novel conformal Vivaldi antenna array with two elements is designed to achieve 3-9 GHz ultra-wideband (UWB) high-gain end-fire radiation. By employing a flexible printed circuit and two Vivaldi antenna elements, this conformal antenna array has a wide bandwidth and low cross-polarization levels. In addition, a feeding network provides a co-phase equal amplitude excitation of the array to create the required high-gain end-fire radiation within the operating band. Simulated reflection coefficient illustrates that an impedance bandwidth of 102.5 % is obtained from 3.06 GHz to 9.5 GHz with vert S_11vert < -10 dB. Within the operating band, the range of realized gain is 8.81-15.18 dBi, and stable end-fire radiation patterns are maintained.
