Antenna Element Design for Emitting UWB Signals

The article provides a study of the antenna configuration with an "E" shape patch and analyzes the impact of the slot size on its broadband response. The aim of the work is to create a small-sized, lightweight and affordable broadband antenna, applicable in navigation and radar, which will meet the requirements for the shape of the radiation pattern and provides a wide bandwidth in UWB technology. The antenna is fabricated and its parameters are measured experimentally. The reflection coefficient, radiation pattern and radiation efficiency are measured within the antenna operating band 5–8 GHz. The measurements and the electromagnetic simulations are compared showing good agreement.
