Abstract: An antenna includes a body having first and second lateral arms. The body also includes a central offset section connecting to the first and the second lateral arms, and first and second antenna ports connected to the central offset section. The antenna has a bandwidth greater than a maximum frequency shift of a resonance frequency of the antenna caused by a loading of the antenna by a human hand.

Abstract: A network system and a method of determining a location of a transmitter are described. The method includes reading a signal strength of a signal transmitted by the transmitter by each of a plurality of receivers, at each frequency in a plurality of frequencies, extracting phase information using an amplitude of the signal at each of the plurality of frequencies, and applying a transform (such as a Fourier Transform) to the signal in the frequency domain to obtain a representation of the signal in the time-domain. The method further includes applying a time window to the signal in the time-domain to eliminate reflected multipath signals that arrive to the respective receivers later than a line-of-sight signal to obtain a windowed signal in the time domain, and calculating a location of the transceiver using the windowed time domain signal.
