The present invention relates to an integrated antenna unit assembly and antenna arrays and antenna packages including the antenna unit assembly. The antenna unit assembly includes a carrier structure, one or more antenna element(s) arranged on a surface of a first edge part of the carrier structure. The integrated antenna unit assembly further includes an integrated circuit (IC) arrangement including one or more circuits mounted on a first surface of a first side of the carrier structure. Further, a first dielectric element mounted on a second surface of the first side of the carrier structure and coupling means arranged to electrically couple the IC to the first dielectric element are also included. The carrier structure of the integrated antenna unit assembly includes a second edge part adapted to be surface mounted on a surface of a second dielectric element.

Packaging for antenna arrays

Systems and methods for linearizing a radio system are disclosed. In some embodiments, a radio system comprises an antenna array, transmit branches comprising respective power amplifiers, a predistortion subsystem comprising predistorters for the transmit branches respectively, a receive antenna element, a transmit observation receiver having an input coupled to the receive antenna element, and an adaptor. The predistorters predistort respective transmit signals to provide predistorted transmit signals to the respective transmit branches for transmission via respective active antenna elements in the antenna array. The transmit observation receiver is operable to receive, via the receive antenna element, a combined receive signal due to coupling between the receive antenna element and the active antenna elements. The adaptor is operable to generate a combined reference signal based on the transmit signals and configure predistortion parameters input to the predistorters based on the combined reference signal and the combined receive signal.
