Abstract: A patch antenna (30) is described with enhanced beamwidth characteristics. In a first embodiment, the antenna comprises a patch element (32) and a ground plane (34) separated from the patch element by a first dielectric layer. The antenna further includes a signal feed line (36) separated from the ground plane by a second dielectric layer, the signal feed line being shielded from the patch element by the ground plane. The signal feed line is electromagnetically coupled to the patch element through an aperture (44) in the ground plane lying across the signal feed line, the ground plane functioning as a finite surface relative to the aperture. According to a further aspect of the invention, the beamwidth of the antenna is adjusted by adjusting the position of a reflector behind the signal feed line. Thus, the present invention provides an efficient way to achieve adjustable wide-beamwidth for various wireless systems in a three-sector configuration.

Abstract: A non-conductive frame supports the resonators in a patch antenna assembly. The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also includ e posts that are used to attach the frames to the feedboard without using additional components such as screws.

Abstract: A non-conductive frame (124,126) supports the resonators (116,118) in a patch antenna assembly (100). The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also include posts (128) that are used to attach the frames to the feedboard (130) without using additional components such as screws.

Abstract: A patch antenna's resonators (116, 118) are supported by a non-conductive frame (124). The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. In one embodiment of the invention, the frame includes a perimeter lip (164) that snaps over the edges of the feedboard (130) and thereby attaches the frame to the feedboard.

Abstract: A phased array antenna includes an active or beam forming array portion (32,34,36,38) and active parasitic elements (30,40) that transmit and/or receive signals. The parasitic elements serve the dual purpose of providing a uniform impedance for elements at the edge of the array portion of the antenna while also providing active elements that are used to transmit and/or receive signals. The active parasitic elements may transmit and/or receive at the same frequency as the array portion or at a different frequency than the array portion. It is also possible for the active parasitic elements to have a different polarization than the elements of the array portion.

Abstract: An antenna (70) is described that comprises an antenna having a patch element (72) fabricated onto a substrate (74), a ground plane (82), and an impedance transformer (80) between the patch element and the ground plane. The patch element is electrically connected to a first end of the impedance transformer, and a feed line (84) is electrically connected to a second end of the impedance transformer through the ground plane. The use of the impedance transformer allows impedance matching to be accomplished without being limited to the physical limitations of the patch element. According to a further aspect of the invention, a patch element is fabricated onto a first substrate surface and a ground plane is fabricated onto a second substrate surface, the ground plane separated from the patch element by a plurality of substrate layers. An impedance transformer is embedded between abutting substrate layers between the patch element and the ground plane, and an electrically conductive via connects a first end of the impedance transformer to a feed point on the patch element. The antenna further includes a coaxial feed having an outer conductor electrically connected to the ground plane and an inner conductor electrically connected to a second end of the impedance transformer, such that a signal is carried between the coaxial feed and the patch element through the impedance transformer.
