Antennas that Support Qorvo-Decawave UWB Technologies | Symmetry Blog

Mar 24, 2021
 

When it comes to designing wireless products, selecting the proper antenna to support your application is vital to system performance. It is therefore recommended that the antenna selection is finalized early in the design phase to avoid costly re-designs. To select the optimal antenna, designers must determine product requirements such as the PCB design, size, and enclosure. Additionally, performance parameters including gain, bandwidth, Voltage Standing Wave Ratio (VSWR), and radiation pattern must also be considered.

A low power, short range, and high bandwidth wireless communication protocol–ultra-wideband (UWB) is an emerging technology that is primarily used for precise device-to-device communications and Real-Time Location System (RTLS) applications. With both internal and external antenna options available, design engineers must utilize a UWB-compatible antenna that is most suitable for their specific use case. Utilizing a wide range of frequencies (channels ranging from 3-10 GHz) – designers must consider the global region that their UWB application will be utilized to ensure the antenna is suitable for the ideal frequency bands. As pioneers in the UWB space, Qorvo-Decawave offers an impressive portfolio of UWB products, including modules, shields, transceivers, and development kits. Offering an Application Engineers’ perspective, the following guide eliminates the guess work and identifies a variety of antenna options that are compatible with Qorvo-Decawave UWB technologies.
