Abstract: Aspects of a protection circuit and method are disclosed. A transmit circuit generates a power transmit signal for powering the transmit antenna to generate a wireless field sufficient for wirelessly charging a device. A detection circuit senses a strength of an electromagnetic field received by the transmit antenna and further configured to generate an sense signal indicating the strength of the electromagnetic field received by the transmit antenna. A power control circuit controls a switch based at least partly on the sense signal. The power control circuit can attenuate an electrical coupling between the transmit antenna and the transmit circuit such that the received electromagnetic field is inhibited from damaging the transmit antenna or the transmit circuit.

Abstract: A multi-band antenna device includes a primary antenna with a helical component and a folded component. A wire is formed in a helix to construct the helical component and a wire is formed in a folded-over fashion to form the folded component. The folded component is disposed inside the helix. The helical component and folded component may be formed with separate wires or as one continuous wire. The primary antenna is for resonating in multiple frequency bands including a first frequency band correlated with the helical component and a second frequency band correlated with the folded component. A secondary antenna may be included to provide diversity and possibly other frequency bands. The secondary antenna includes a planar inverted F antenna.
