Patent number: 7898485Abstract: Handheld electronic devices are provided that contain wireless communications circuitry having at least first and second antennas. An antenna isolation element reduces signal interference between the antennas, so that the antennas may be used in close proximity to each other. A planar ground element may be used as a ground by the first and second antennas. The first antenna may be formed using a hybrid planar-inverted-F and slot arrangement in which a planar resonating element is located above a rectangular slot in the planar ground element. The second antenna may be formed from an L-shaped strip. The planar resonating element of the first antenna may have first and second arms. The first arm may resonate at a common frequency with the second antenna and may serve as the isolation element. The second arm may resonate at approximately the same frequency as the slot portion of the hybrid antenna.Type: GrantFiled: July 16, 2009Date of Patent: March 1, 2011Assignee: Apple Inc.Inventors: Robert W.

Patent number: 7889139Abstract: A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables.

Patent number: 7864123Abstract: Handheld electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include an antenna. The antenna may be formed from a ground plane having a dielectric-filled slot that defines a slot antenna structure and having a planar-inverted-F (PIFA) resonating element located above the opening. The slot antenna structure and the PIFA resonating element may both contribute to the performance of the antenna, so that the antenna exhibits the performance of a hybrid PIFA-slot antenna. The PIFA resonating element may contain multiple antenna resonating element branches. The branches may be configured to operate in different communications bands than the slot antenna structure.Type: GrantFiled: August 28, 2007Date of Patent: January 4, 2011Assignee: Apple Inc.Inventors: Robert J.

Patent number: 7768462Abstract: A handheld electronic device is provided that contain wireless communications circuitry. The wireless communications circuitry may include antenna structures. A first antenna may handle first and second communications bands. A second antenna may handle additional communications bands. The first and second antennas may be located at opposite ends of the handheld electronic device. Conductive structures in the handheld electronic device may form an antenna ground plane. The antenna ground plane may have portions defining an antenna slot. An L-shaped antenna resonating element may be located adjacent to the slot. In the first communications band, the L-shaped antenna resonating element may serve as a non-radiating coupling stub that excites the antenna slot. In the second communications band, the L-shaped antenna resonating element may transmit and receive radio-frequency signals.Type: GrantFiled: August 22, 2007Date of Patent: August 3, 2010Assignee: Apple Inc.Inventors: Zhijun Zhang, Robert W.

Patent number: 7764236Abstract: Broadband antennas and handheld electronic devices with broadband antennas are provided. A handheld electronic device has integrated circuits, a display, and a battery mounted within a housing. The housing has a planar inner surface. A broadband antenna for the handheld electronic device has a ground element and a resonating element. The ground element and resonating element may have the same shape and may have the same size. The ground element and resonating element may lie in a common plane and be separated by a gap that lies in the common plane. The plane in which the ground element and resonating element lie may be parallel to the planar inner surface of the housing. Electronic components such as the integrated circuits, display, and battery can be mounted in the handheld device so that they do not overlap the gap between the ground element and the resonating element.Type: GrantFiled: January 4, 2007Date of Patent: July 27, 2010Assignee: Apple Inc.Inventors: Robert J.

Publication number: 20100060529Abstract: Handheld electronic devices are provided that contain wireless communications circuitry. The wireless communications circuitry may include antenna structures. To accommodate manufacturing variations, the antenna structures and handheld electronic devices may be characterized by performing measurements such as antenna performance measurements. Appropriate antenna adjustments may be made during manufacturing of a handheld electronic device based on the characterizing measurements. An antenna may be formed using an inverted-F design in which an antenna flex circuit is mounted to a dielectric antenna support structure. Cavities in the support may be selectively filled with dielectric material and dielectric patches may be added to the antenna flex circuit to adjust the dielectric loading of the antenna. The length of a ground return path in the antenna may be adjusted by appropriate positioning of an electrical connector within the ground return path.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Inventors: Robert W.
