Abstract:
An antenna arrangement including a ground plane having an electrical length; an antenna element positioned for coupling with the ground plane; a first conductive element; an interconnecting mechanism, connected to the ground plane and to the first conductive element, having a first configuration and a second configuration, wherein the ground plane has a first electrical length when the interconnecting mechanism is in the first configuration and a second electrical length, different to the first electrical length, when the interconnecting mechanism is in the second configuration.
Abstract:
A radio antenna assembly for use in a communication device has an antenna element disposed adjacent to a ground plane to form a physical relationship with the ground plane. A mechanical device is used to change the physical relationship for changing the operating impedance of the antenna element or shifting the frequency band of the antenna assembly. The physical relationship can be changed by mechanically changing the shape of the antenna element. When the antenna element comprises a first radiating element and a second radiating element disposed at a lateral distance from the first radiating element, the physical relationship can be changed by changing the distance. When a physical object is disposed between the antenna element and the ground plane, the physical relationship can be changed by moving or twisting the physical object. The object can be electrically conducting, dielectric or magnetic.
Abstract:
The specification and drawings present a new apparatus and method for antenna arrangement by providing a feed arrangement through a flex connection for radiating elements of a first part and a second part (e.g., lower and upper parts, respectively) of a mobile terminal (e.g., a slide-type terminal), wherein the first and second parts are configured to move relative to each other during operation of the mobile terminal. For a slide-type terminal, the first and the second parts can be sliding relative to each other during said operation. This antenna arrangement can be used by any of the cellular or non-cellular wireless systems.

Abstract:
A radio antenna including a first shorted patch having a first resonance frequency (GSM1800), a second shorted patch having a second resonance frequency (E-GSM) connected to the first shorted patch for sharing a feed point, and a third shorted patch having a third resonance frequency (GSM1900) located adjacent to the second shorted patch. The second shorted patch has an extended portion surrounding at least two sides of the first shorted patch, leaving a gap therebetween. The third shorted patch serves as a parasitic patch to increase the bandwidth of the second shorted patch. Part of the extended portion of the second shorted patch is extended beyond the top edge of the ground plane to which the patches are grounded.
