An antenna arrangement including an antenna occupying at least a first plane; a conductive structure that is isolated from the antenna but is arranged to be parasitically fed by the antenna, the conductive structure having a slot and occupying at least a second plane different to but adjacent the first plane.

Antenna arrangement and antenna housing

Apparatus () comprising: an antenna () connectable to a first terminal () and to a second terminal () and comprising a first conductive part () and a second conductive part (), the first conductive part being configured electrically in parallel with the second conductive part, the first conductive part () being configured to have a first electrical length and the second conductive part () being configured to have a second electrical length together providing a common resonant mode having a first operational frequency band, the second conductive part () substantially providing a common resonant mode having a second operational frequency band and the first conductive part () substantially providing a differential resonant mode having a third operational frequency band.

Apparatus for wireless communication comprising a loop like antenna

An apparatus including: a first antenna element; a second antenna element; a ground plane element for at least one of the first and second antenna elements; a first choke arranged to affect a first maximum of current density produced in the ground plane element by the first antenna element; and a second choke arranged to affect a second maximum of current density produced in the ground plane element by the second antenna element.

Radiation pattern control

A multi-part, distributed antenna arrangement including: an antenna element as a first part; and a semiconductor chip as a second part, separated from the first part, wherein the semiconductor chip comprises integrated radio frequency circuitry and a coupling element for wirelessly coupling the integrated radio frequency circuitry with the antenna element.

Antenna arrangement

This invention describes a method for improving antenna isolation in an electronic communication device using grounded RF microwave elements and patterns (structures). According to embodiments of the present invention, the RF microwave element can be implemented as a short-circuited section of a quarter-wavelength long transmission line (such as a stripline), or the RF microwave element can contain a metallic coupler and two thin striplines with different lengths, or the RF microwave element can be implemented using a balun concept.

Antenna isolation using grounded microwave elements

An antenna configuration for a mobile communication device. The antenna configuration includes at least a first antenna configured so that the first antenna may be mounted near or between a speaker and a earpiece of a mobile station. In an embodiment of the invention, the first antenna comprises a substantially flat conductor including at least one hole for passing sound from the speaker to the earpiece of the mobile station. The first antenna is configured to receive GPS signals. A second antenna is implemented on the mobile station to transmit and receive cellular transmissions.
