System and method for material bending

Dispersive surface antenna structures ( ) provide improved selectivity and increased control over bandwidth. Antenna structures ( ) include a wraparound piece of conductive material located perpendicular to a ground plane ( ). Ground posts ( ) extend up from the ground base ( ) and capacitively couple to a front conductive surface ( ) of the antennas ( ). First and second conductive back surfaces ( ), ( ) are capacitively coupled across a gap ( ) along the back of the antennas ( ). The size, width, and location of the gap ( ) along with the ground posts ( ) provide increased control over antenna performance.

Dispersive surface antenna structures (300, 700) provide improved selectivity and increased control over bandwidth. Antenna structures (300, 700) include a wraparound piece of conductive material located perpendicular to around plane (304, 704). Ground posts (302, 702) extend up from the ground base (304) and capacitively couple to a front conductive surface (301, 701) of the antennas (300, 700). First and second conductive back surfaces (305, 306), (705, 706) are capacitively coupled across a gap (307, 707) along the back of the antennas (300, 700). The size, width, and location of the gap (307, 707) along with the ground posts (302, 702) provide increased control over antenna performance.

A microstrip antenna (300) includes a substrate (302) having an inner ground plane layer (322) around which a radiator element is folded so as to form first and second radiator patches (310, 312) on either side of the ground plane.

A double resonant wideband patch antenna (100) includes a planar resonator (101) forms a substantially trapezoidal shape having a non-parallel edge (103) for providing a substantially wide bandwidth. A feed line (107) extends parallel to the non-parallel edge (103) for coupling while a ground plane (111) extends beneath the planar resonator for increasing radiation efficiency.

An energy diversity antenna (100) includes a first antenna (103) and second antenna (113) positioned on a substrate (101). The first antenna is preferably a loop used for receiving radio frequency signals with H-field energy while the second antenna is preferably a monopole used for receiving radio frequency signals with E-field energy. The energy diversity antenna (100) is applicable for use in portable communications devices capable of diversity reception. It is particularly useful in geographic locations where reflections and multipath interference is a problem.

Energy diversity antenna

An antenna comprises a feed port, a 1/2 wavelength radiator (20), and a double resonant transformer (10). The feed, port, having a signal feed portion (34) and a ground portion (44), is at a low impedance while the 1/2 wavelength radiator (20) has opposed high impedance ends (21 and 22). For transforming low impedance to high impedance, at two resonant frequencies, the double resonant transformer is coupled between the feed port and the 1/2 wavelength radiator.

A dual loop antenna (100) provides a dual frequency band response. The dual loop antenna (100) is configured on a substrate (102) which includes first and second radiator elements (106, 206) coupled through a common feed element (108).
