Slotted PIFA for Mobile Communication Devices
Abstract
Slotted PIFA with capacitive loading for operation in the 880 / 960 MHz band is presented. The PIFA is intended for mobile terminals in GSM mobile communication network. The antenna is placed on a ground plane with dimensions of an average handheld device. It is optimized by using electromagnetic simulator and a prototype is manufactured. Calculated and measured results agree very well. Input impedance matching with SWR < 3 in the whole band was achieved. Maximum gain of 3.2 dBi is measured. Preliminary studies of the influence of the user's head and hand on the antenna characteristics have been performed.
