This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.

An electronic device may include a conductive housing with a rear wall and a sidewall. A display may be mounted to the sidewall and may include a conductive display structure separated from the sidewall by a slot. An antenna arm may be interposed between the conductive display structure and the rear wall. A first inductor may couple the conductive display structure to the housing and may compensate for a distributed capacitance between the antenna arm and the conductive display structure. A second inductor may couple the antenna arm to the rear wall and may compensate for a distributed capacitance between the antenna arm and the rear wall. A speaker may be co-located with the antenna. A third inductor may couple the antenna arm to the rear wall to allow antenna currents to bypass the speaker.
