Fig. 18From: A residential maintenance-free long-term activity monitoring system for healthcare applicationsThe antenna polarisation significantly affects the PER in several links. Each pair of bars shows the PER of the vertical (left bar) and horizontal (right bar) dipole of a certain link, defined by the wearable location (W) and a certain transmission power level in decibel-milliwatts. This demonstrates the benefit of exploiting antenna polarisation orthogonality at the receiverBack to article page
