The small ground requirement is an advantage for designers on a small circuit board, such as miniature pet trackers, wearable devices, or OBD-II designs.
This antenna was tested with 50 x 40 mm and 60 x 40 mm evaluation boards. Typically, these require a minimum footprint of 60 x 40 mm, utilize large and expensive band-switching networks, and exhibit lower efficiency levels.
Antenova supplies the Pharaoh SR4L073 antenna with a reference design and corresponding network to help integrate the antenna into a device and shorten the design cycle.
