UWB antenna design

What makes UWB devices different from antenna design perspective?

WHY to use UWB

Ultra-Wide Band (UWB) is a special technology used for high-speed, low power, short-range wireless communication, and positioning. It differs from many other technologies by spreading the signal over huge chunk of radio spectrum (split in 500MHz channels). Obtaining this kind of antenna bandwidth is obviously major challenge for antenna design. For positioning application both directional and omnidirectional antennas are needed depending on installation. Indoor positioning system is one example we have worked with.

Data communication

Enables short-range, low-latency data exchange with robust performance in dense environments, supporting precise timing and reliable links with minimal interference.

Ranging

Provides highly accurate distance and position measurements through precise time-of-flight, enabling real-time localization with centimeter-level accuracy and strong multipath resilience.

Sensing

Supports fine-resolution motion and presence sensing by capturing subtle signal reflections, enabling detailed environmental awareness with low power consumption.

Main challenges at UWB antenna design

Beside the obvious bandwidth and posible multichannel requirement, UWB antennas have design criterias that are not very common for other antennas.

Antenna simulations are critical at reaching accurate performance forecast in early stages of development enabling informed decisions before manufacturing of prototypes. Simulation enable us to use our extensive know how in product integration to find new innovative antenna solutions.

Radiation pattern control

Many antenna types work well with specified PCB ground size. However, if the ground gets larger radiation pattern starts to tilt for directional antenna or cause a null for omnidirectional antenna.

Group delay

For UWB to function as positioning system, there should not be changes at any frequency in group delay in respect to angle of arrival. Group delay gets easily distorted by poor integration or wrong antenna type.
