- Abstract
- The emergence of miniaturized flexible electronics enables on-duty first responders to collect biometrical and environmental data through multiple on-body sensors, integrated into their clothing. However, gathering these life-saving data would be useless if they cannot set up reliable, preferable high data rate, wireless communication links between the sensors and a remote base station. Therefore, we have developed a fourelement ultra-wideband textile cross array, that combines dualspatial and dual-polarization diversity, and is easily deployable in a first responder’s garment. The impedance bandwidth of the array equals 1.43 GHz, while mutual coupling between its elements remains below -25 dB. For a maximal bit error rate of 1e-4, the array realizes a diversity gain of 24.81dB. When applying Adaptive Subcarrier modulation, the mean throughput per OFDM subcarrier increases by an extra bit/symbol when comparing fourth to second order diversity.
