A Multiband and Omnidirectional, CPW-Fed Single-Layer Based Dual Tapered-Slot Antenna

Travelling wave antennas such as Vivaldi antennas, have conventionally been used for obtaining wideband and directional radiation pattern. This paper presents a novel way to obtain first of its kind, omnidirectional travelling wave antenna inspired by Vivaldi. Traditional omnidirectional antennas such as monopole and dipole rely on resonance condition which is usually satisfied on narrow band while the proposed antenna is relatively broadband owing to its travelling wave phenomenon. Moreover, typical Vivaldi antennas are double layered while our design requires only one layer. Antenna has been simulated and optimized in HFSS to operate in dual bands of UWB spectrum. The antenna has been measured and characterized using Keysight handheld VNA and Satimo Anechoic chamber. Good agreement between simulations and measurements have been obtained despite the fabrication tolerance of LPKF PCB manufacturing machine.
