Issues include orientation and polarization, matching, coupling, reflections, phase center,  and physical size. Designing and creating antennas can easily lead to inconsistent results due to the affects of hardware, cables and other testing equipment in the vicinity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have previously mentioned that antenna design is a complex area that will slow the rollout of Bluetooth AoA direction finding solutions.
