A dual-band antenna includes a first antenna element having a generally 'J' shaped element, and a second antenna element having a generally 'h' shaped element. The first antenna element and the second antenna element share a common feed point and each antenna element is oriented substantially perpendicular to the other. The first antenna element and the second antenna element, in one implementation, are adapted to efficiently operate the dual-band antenna at approximately 1575 MHz and approximately 850 MHz, respectively.

H-J antenna

A radiator for an RF communication device () including a first member () including a first conducting surface () operable to provide a radiating surface, a second member () including a second conducting surface () operable to provide a near field reflector or ground plane surface, the first conducting surface and the second conducting surface being galvanically connected (by), wherein the first conducting surface is disposed at an angle relative to the second conducting surface and the first conducting surface includes a first conducting region () and a second conducting region () having between them a gap () having a portion () which is tapered.

Radiator for an RF communication device

An antenna structure for use in a wireless communication device, the structure comprising (i) a plurality of antenna portions each having a substantially planar radiating surface and (ii) a conducting ground portion; wherein the radiating surfaces of the antenna portions are substantially parallel to one another in a side-by-side relationship and are substantially parallel to part of the conducting ground portion located behind the antenna portions with respect to a direction of transmission of radiation from the antenna portions, the conducting ground portion comprising a first part galvanically connected to each of the antenna portions and, electrically coupled to the first part, a second conducting part forming at least part of a cover for a wireless communication device.

Antenna structures and their use in wireless communication devices

An antenna device () includes a conducting base (), an elongate conducting element () coupled to and extending from the conducting base and a parasitic conductor () connected to and extending from the conducting base. The device is configured to provide in operation in a plurality of frequency bands omnidirectional radiation patterns in two mutually orthogonal planes (x-y; x-z). The radiation of these patterns may conveniently have the same polarization.
