Patent number: 6914568Abstract: 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 non-conductive 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.Type: GrantFiled: July 22, 2003Date of Patent: July 5, 2005Assignee: Centurion Wireless Technologies, Inc.Inventors: Vladimir Stoiljkovic, Shanmuganthan Suganthan, Peter Webster

Patent number: 6639562Abstract: 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.Type: GrantFiled: December 17, 2001Date of Patent: October 28, 2003Assignee: Centurion Wireless Tech., Inc.Inventors: Shanmuganthan Suganthan, Peter Webster

Patent number: 6437747Abstract: A tunable PIFA antenna is disclosed for use with wireless communication devices. In three embodiments of the invention, a movable tuning member constructed of a high-dielectric constant material is selectively moved with respect to the feed and shorting pins of the antenna to vary the frequency response of the antenna. In the fourth embodiment, a slot is molded into the frame of the antenna. The size and position of the slot is varied by the molding tool to vary the frequency response of the antenna.Type: GrantFiled: April 9, 2001Date of Patent: August 20, 2002Assignee: Centurion Wireless Technologies, Inc.Inventors: Vladimir Stoiljkovic, Peter Webster, Shanmuganthan Suganthan
