Antena de alta eficiencia para localización en entornos hospitalarios

Abstract

[EN] In this paper, an omni-directional antenna solution is presented to improve the accuracy of indoor location systems, particularly MYSPHERA Bluetooth Real-Time Locating System (RTLS). Emitting antennas with an irregular radiation pattern are not suitable for existing localization techniques due to received signal strength variation in the locators. The approach to an isotropic radiation pattern in the emitting device is what is achieved with presented design using two time-switched antennas with opposing radiation patterns. This solution allows to receive a uniform signal in the locators and increases precision for any technique, frequency or technology used. For MYSPHERA this means more reliability, allowing better processes optimization and increasing efficiency in hospitals.
