Electronic Device With Millimeter Wave Antennas
First Claim
1. An electronic device, comprising:
- a housing;
a baseband processor;
a plurality of phased antenna arrays;
a plurality of transceiver circuits each of which is associated with a respective one of the phased antenna arrays and each of which includes a radio-frequency transceiver; and
a plurality of intermediate frequency signal paths each of which is coupled between the baseband processor and a respective one of the transceiver circuits, wherein each transceiver circuit includes an upconverter that receives intermediate frequency signals from the baseband processor over a respective one of the plurality of intermediate frequency signal paths and that upconverts those intermediate frequency signals to radio-frequency signals that are provided to a respective one of the phased antenna arrays and wherein each transceiver circuit includes a downconverter that receives radio-frequency antenna signals from that respective one of the phased antenna arrays and downconverts those received radio-frequency antenna signals to intermediate frequency signals that are conveyed to the baseband processor over the intermediate frequency signal path that is coupled to that respective transceiver circuit.

Abstract
An electronic device may be provided with wireless circuitry. The wireless circuitry may include one or more antennas. The antennas may include phased antenna arrays each of which includes multiple antenna elements. Phased antenna arrays may be mounted along edges of a housing for the electronic device, behind a dielectric window such as a dielectric logo window in the housing, in alignment with dielectric housing portions at corners of the housing, or elsewhere in the electronic device. A phased antenna array may include arrays of patch antenna elements on dielectric layers separated by a ground layer. A baseband processor may distribute wireless signals to the phased antenna arrays at intermediate frequencies over intermediate frequency signal paths. Transceiver circuits at the phased antenna arrays may include upconverters and downconverters coupled to the intermediate frequency signal paths.
