Antenna system for signal-attenuating containers

摘要

A system can include a container that includes a cabinet capable of attenuating or blocking wireless signals, an AED located within the cabinet, an internal patch antenna removably mounted to an internal surface of the cabinet, an external patch antenna removably mounted to an external surface of the cabinet, and an electrical connection between the internal patch antenna and the external patch antenna. The internal and external patch antennas can be configured to transmit wireless signals at a particular frequency and to receive wireless signals at the particular frequency. The system can be configured such that the internal patch antenna is operative to receive a first wireless signal from the AED, a first electrical signal based on the first wireless signal is provided via the electrical connection to the external patch antenna, and a second wireless signal based on the first electrical signal is radiated by the external patch antenna.

主权项

1. A system comprising:
an automated external defibrillator (AED) configured to be located within a cabinet capable of attenuating or blocking wireless signal transmission, the AED configured to communicate wireless signals at one or more particular frequencies, wherein the AED is configured to perform one or more of the following via the wireless signals: AED location, AED software updates, AED state or errors, AED event data, or remaining shelf life of time sensitive components of the AED; an internal patch antenna configured to be removably mounted to an internal surface of the cabinet, the internal patch antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies; an external patch antenna configured to be removably mounted to an external surface of the cabinet, the external patch antenna configured to transmit wireless signals at the one or more particular frequencies and to receive wireless signals at the one or more particular frequencies; and an electrical connection between the internal patch antenna and the external patch antenna; wherein the system when deployed is configured such that the internal patch antenna is operative to receive a first wireless signal from the AED, a first electrical signal based on the first wireless signal is provided via the electrical connection to the external patch antenna, and a second wireless signal based on the first electrical signal is radiated by the external patch antenna.
