The Toaglas UWC.40 chip antenna, at 6 x 7 x 3 mm, is a small form factor ultra-wideband (UWB) antenna with high efficiencies across the pulsed UWB communications operational bands. It enables designers to use just one antenna to simultaneously cover all common UWB commercial bands, namely bands 1-4. UWC.40 provides a peak gain of 4 dBi and efficiencies of more than 80% across most of the UWB bandwidth.
The UWC.40 is a durable ceramic antenna designed to be mounted directly to a PCB via standard SMT reflow process. It is an ideal choice for any device maker that needs to keep manufacturing costs down over the lifetime of a product. This antenna can be used in applications such as automotive sensors, smart airbags, precision surveying, smart home and entertainment systems and with any other application requiring indoor centimetre-level tracking.
Care should be taken to mount the antenna at least 1 mm from metal components or surfaces, and ideally 5 mm for best radiation efficiency. Nearby metal components should be as small as possible. The antenna will not work within fully enclosed metal enclosures. Minimum recommended ground plane size is 26 mm x 20 mm, and antenna to ground clearance is fixed to 2,5 mm and should not be changed.
