Embodiment Construction

[0023] This application claims priority to US Patent Application No. 13 / 468,289, filed May 10, 2012, which is hereby incorporated by reference in its entirety.

[0024] Electronic devices may have antennas, sensors, and other electronic components. It is desirable to form some of these components by flexible structures. For example, it is desirable to use flexible printed circuit structures to form components for electronic devices. Flexible printed circuits, sometimes called flex circuits, may include patterned metal traces on a flexible substrate, such as a polyimide layer or other flexible polymer sheet. Flexible circuits can be used to construct antennas, capacitive sensors, accessories including antenna and capacitive sensor structures, other electronic device components, or combinations of these structures.

[0025] In some cases, it is desirable to form conductive electronic component structures with bends and other potentially complex shapes. For example, antennas, ...

Abstract

The present disclosure relates to antenna and proximity sensor structures having a printed circuit and a dielectric carrier layer. An electronic device may have a conductive housing with an antenna window. The display overlay can be mounted on the front of the device. The antenna and proximity sensor structure includes a dielectric support structure with cutouts. The antenna window may have a protruding portion that extends into the cutout between the display cover and the antenna and proximity sensor structure. The antenna and proximity sensor structure has an antenna feed coupled to the first conductive layer by a high pass circuit, and a capacitive proximity sensor circuit coupled to the first conductive layer and a parallel second conductive layer by a low pass circuit. The first conductive layer consists of a metal coating on the support structure. The second conductive layer may consist of patterned metal traces on the flexible printed circuit.

Description

technical field [0001] The present disclosure relates generally to electronic devices, and more particularly to antennas in electronic devices. Background technique [0002] Electronic devices, such as portable computers and handheld electronic devices, are becoming more and more popular. Devices such as these often have wireless communication capabilities. For example, electronic devices may communicate using long-range wireless communication circuits using cellular telephone bands. Electronic devices may handle communications with nearby devices using short-range wireless communication links. Often, electronic devices also have sensors and other electronic components. [0003] Successfully incorporating antennas, sensors, and other electronic components into electronic devices can be difficult. Some electronic devices are manufactured with small form factors, so space for components is limited. In many electronic devices, the presence of conductive structures can affe...
