An integrated circuit package is provided. The integrated circuit package comprises a transceiver radio-frequency integrated circuit, RFIC, and at least one antenna array formed in a redistribution metal layer of the integrated circuit package, and is arranged in a fan-out area of the RFIC. The at least one antenna array comprises at least one crossed dipole antenna. Each crossed dipole antenna comprises a first dipole comprising two first legs, and a second dipole comprising two second legs, and two leg pairs, each leg pair comprising one first leg of the first dipole and one second leg of the second dipole, and two feed lines. Each feed line is coupled to a respective leg pair at a center of the crossed dipole antenna. At least a part of each feed line is arranged between the two leg pairs.

System includes first and second amplifying circuits that are configured to receive input signals having a fundamental frequency. The system also includes first and second transmission lines that are configured to receive voltage and current waveforms from the first and second amplifying circuits, respectively. The system also includes a capacitively-compensated transmission line resonator (CC-TLR) that is configured to be electrically connected to a load having a load impedance. The CC-TLR is configured to receive and combine RF power from the first and second transmission lines. The CC-TLR has a compensation capacitance that causes the CC-TLR to present an open circuit at the fundamental frequency and present a short circuit at harmonic frequencies. Optionally, a characteristic impedance (Z) of the first and second transmission lines and a load impedance (Z) are unequal, and the first and second transmission lines cause a load impedance transformation.

Power combiner/divider includes a transmission line (TL) resonator having an inner conductor, an outer conductor that surrounds the inner conductor, and a cavity between the inner conductor and the outer conductor. The inner conductor and the outer conductor are electrically connected at a proximal end of the TL resonator. The power combiner/divider also includes coupling elements extending through respective openings of the outer conductor and into the cavity. The power combiner/divider also includes a capacitive element connected to at least one of the inner conductor or the outer conductor. The capacitive element capacitively couples the inner conductor and the outer conductor at a distal end of the TL resonator.

A microfabricated sensor () for detecting a component in bodily fluid, includes: an inlet () for receiving a sample of bodily fluid, a fluid cavity () connected to the inlet for receiving the sample of bodily fluid from the inlet, and an RF resonant cavity (), delimited by walls (). At least one of the walls forms a separating wall (), separating the fluid cavity from the RF resonant cavity, wherein the separating wall is configured such that the dielectric properties of the bodily fluid in the fluid cavity provide an influence on the electromagnetic properties of the RF resonant cavity.
