A UWB antenna is a type of antenna whose purpose is to transmit or receive electromagnetic waves from within a range of specified frequency bands. These types of antennas are usually critical to the functioning of ultra wideband systems.
Without them UWB devices cannot transmit or receive UWB signals. Usually, this kind of antennas have what is known as a “broad frequency response”, which allows them to cover the required wide range of frequency bands needed for uwb technology.
They achieve this through complex geometries, state-of-the-art feeding techniques, and an array of resonant nodes. UWB antennas can be printed, planar, horn, or monopole in design. The appropriate choice will depend on the specific application and requirements.
