Abstract: A compact planar antenna is disclosed wherein a radiating element in the shape of a right triangle is formed on a substrate. A ground plane may be positioned on one or both sides of the substrate. In one embodiment, the radiating elements are positioned on the substrate in groups of two or more in close proximity to one another. In another embodiment, the radiating elements are arranged in an array.

Abstract: A stubby antenna comprising a RF conductive connector stud having opposite ends with the stud including means for mounting the antenna in the mounting hole of a communications device such as a cellular telephone. The stud is press-fitted into a body member with the body member having an opening or compartment formed therein which receives a coilform having a coil radiating element and a center wire. The coil radiating element is comprised of a plurality of first coils and a plurality of second coils with the first plurality of coils having a different pitch than the second plurality of coils. The center wire of the radiating element extends through the coils and through the actual bore formed in the coilform. A sheath encloses the body member with the sheath, body member, conductor stud and radiating element being arranged such that the radiating element is held in compression, ensuring that a good electrical contact is made between the connector stud and the radiating element.

Abstract: A Planar Inverted F Antenna (PIFA) and a radio module integrated into a single module. The present invention permits the PIFA to be removably secured on the top of a radio chip module. In one embodiment of the invention, a dielectric antenna frame is removably secured to a radio chip. A radiating element or “patch” is then secured to the top of the frame. The patch has feed and shorting pins connected thereto. The integrated radio/antenna system can be mounted on a PCB using standard surface-mount techniques and the feed and shorting pins can be soldered to the PCB. In another embodiment of the invention, a cover is removably secured to the frame to retain the patch on the frame. The cover has a window to permit the feed and shorting pins to be soldered to the PCB.

Abstract: A compact, multi-band planar antenna for wireless communication devices is disclosed and which comprises a dielectric substrate having a first radiating element formed on one side thereof. The radiating element has a triangular shape and has an opening formed therein. A ground plane element is formed on the other side of the substrate. Various embodiments of the antenna are also disclosed.
