Apple patent is for dual-band antenna on a desktop computer



Apple has been granted a patent (number 8269677) by the U.S. Patent & Trademark Office for a dual-band cavity backed antenna for an integrated desktop computer -- in other words, the iMac.

Per the patent, an electronic device may have a housing with conductive housing walls. A dielectric antenna window may be formed in an opening in one of the conductive housing walls. A dielectric logo may form the dielectric antenna window. A dielectric support structure may have an outline that matches the dielectric logo. An antenna resonating element for an antenna may be formed on the dielectric support structure.

An antenna cavity for the antenna may be formed by a conductive cavity structure. A pattern of voids in the dielectric support structure may reduce dielectric loading for the antenna. The conductive cavity structure may be formed from solderable plated metal. The conductive cavity structure may have a planar lip that is attached to the conductive housing walls using conductive adhesive. Rear wall portions of the conductive cavity structure may be oriented at a non-perpendicular non-zero angle with respect to the planar lip.

Here's Apple's background on the invention: "Electronic devices such as computers and communications devices are often provided with wireless communications capabilities. For example, electronic devices may use long-range wireless communications circuitry such as cellular telephone circuitry to communicate using cellular telephone bands at 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz (e.g., the main Global System for Mobile Communications or GSM cellular telephone bands).

"Long-range wireless communications circuitry may also be used handle the 2100 MHz band and other bands. Electronic devices may use short-range wireless communications links to handle communications with nearby equipment. For example, electronic devices may communicate using the WiFi (IEEE 802.11) bands at 2.4 GHz and 5 GHz (sometimes referred to as local area network bands) and the Bluetooth band at 2.4 GHz.

"It can be difficult to incorporate antennas successfully into an electronic device. Space for antennas is often limited within the confines of a device housing. Antenna operation can also be blocked by intervening metal structures. This can make it difficult to implement an antenna in an electronic device that contains conductive display structures, conductive housing walls, or other conductive structures that can potentially block radio-frequency signals. It would therefore be desirable to be able to provide improved antennas for electronic devices."

The inventors are Jerzy Guterman, Eduardo Lopez Camacho, Mattia Pascolini, Ayala Enrique Vazquez, Robert W. Schlub and Ruben Caballero

Apple was also granted a patent (number 8270914) for a bezel gap antenna, which is apparently the ones used in the iPhone 4 -- and which was the object of the "antennagate" brouhaha.
