Abstract
A low-height PIFA-fed antenna system having high gain, wide bandwidth and wide beamwidth for applications on wireless communications devices. The antenna is suitable for internal installation within a handset, such as a cellphone. The antenna includes a ground plane conductor, such as the ground plane of a wireless device, and a resonator element having a top portion with a split free end defining an open space. The antenna is well adapted for high volume manufacturing processes using conventional fabrication techniques such as metal stamping or selectively plated plastic.
