Although traditional designs achieve performance requirements by placing antennas for separate radio applications far apart to minimize coupling, recent trends require antennas to be placed within close proximity of each other due to space constraints. To enable both near‐field wireless powering and far‐field data communication on a single device, this letter describes the design of small antennas with both Bluetooth and near‐field communication capabilities. The results for three distinct antenna designs indicate that combining disparate field regimes into a single dual‐band antenna can be used to optimize performance for the particular application. © 2015 Wiley Periodicals, Inc.
