UWB Omnidirectional Antenna Integration Solution
Unictron has developed a dedicated UWB antenna for UWB automotive applications, supporting UWB module solutions such as NXP, which are primarily used in Keyless Entry, AoA vehicle positioning, liveness detection and kick-to-open tailgate functions. Design requirements for UWB antennas include an omnidirectional radiated field pattern in the horizontal direction with high gain consistency. In addition, AOA (Angle of Arrival) vs. TDOA (Time Difference of Arrival) applications require a multi-antenna array configuration to precisely detect the angle and time differences between the individual antennas.
When it comes to these technical requirements, Unictron’s patented Pillar® antenna design architecture is a perfect match for:
- Small group delay error and high gain consistency: Through the symmetrical antenna structure design, the radiated field pattern has a high degree of consistency with a stable phase center, ensuring that the group delay at all angles is consistent.
- Multi-antenna configuration optimization: The radiated current is efficiently diverted to the direction perpendicular to the ground plane, and the current is concentrated in and around the antenna body, so as to improve the isolation between antennas. Simultaneously, this design requires a small headroom, making it ideal for multi-antenna system configurations.
As can be seen from the comparison table below, Unictron’s UWB antenna achieves the most optimal balance between performance and cost, and is the most cost-effective solution.
Owing to the above technical features discussion and performance-comparison review, Unictron’s UWB omnidirectional antenna is certainly the top candidate to fulfill the needs of automotive applications due to its innovative design and excellent performance. Considering gain consistency, group delay control, or configuration efficiency of multi-antenna systems, Unictron’s solutions demonstrate outstanding performance with most competitive price and provide strongest enhancement for the application of UWB technology.
