Antennas are provided which are constructed using one or more wires as radiating elements attached to a substrate or chip, wherein wire bonding methods can be used to attach and form loop profiles for the wires. The system includes a capacitive core, differential amplifier with inverting and non-inverting inputs, capacitive paths, and chopping system. End closures can then be applied to the ends of the container body. In one mode of operation, upon sensing the presence of carbon monoxide, the cellular transceiver automatically initiates a 911 emergency call, transmitting emergency identification information over a wireless E-911 location system to a 911 public safety answering point operator, who dispatches public safety personnel to the location of the emergency carbon monoxide incident.
