US 11,686,792 B2 · Receive coil arrangement and method for use thereof

Abstract

An exemplary coil arrangement can be provided, which can include, for example, coil element(s) having a parallel resonant circuit at a port, where the coil element(s) is detuned by causing a low impedance at the port. Pre-amplifier arrangements can provide a low impedance at the port of the coil element(s) to suppress the induced current on the coil element(s) thereby reducing the inductive coupling to neighboring element(s). The coil element(s) can include an inductance and a capacitance which cancel each other out. The inductance and the capacitance can cancel each other out such that an impedance of the coil element has no imaginary part at a working frequency. An impedance of the coil element(s) in free space includes a real part that can be greater than a sum of losses for the coil element(s).

Dependent claims

A coil arrangement, comprising:

at least one coil configuration having a parallel resonant circuit at a port, wherein:
the at least one coil configuration includes an inner conductor, a substrate, and an outer conductor, and the substrate being provided between the inner conductor and the outer conductor,
the at least one coil configuration is detuned by a detuning circuit configured to cause a low impedance at the port, wherein the detuning circuit includes at least one of (i) at least one positive-intrinsic-negative (PIN) diode, or (ii) at least one Micro Electronic Mechanical Systems (MEMS) switch, and
at least one of (i) the at least one PIN diode or (ii) the at least one MEMS switch is directly electrically connected to the inner conductor and the outer conductor;
wherein, during a receiving mode, two ends of the port are connected to two ends of the inner conductor.
