Abstract :
This paper proposes a new antenna technique for flexible printed monopole antenna (FPMA) as a radiator. This meander lines FPMA based on two asymmetric meander lines with flexible structure exhibits good performances. Meander lines FPMA radiator has the merits to improve antenna bandwidth with fine frequency tuning. The PDA phone for CDMA2000 cellular (824-894 MHz), PCS (1850-1990 MHz) and GPS (1571.42-1579.42 MHz) applications is well demonstrated with the integration and measurement of the co-designed FPMA. Based on 3D far field antenna measurement system to get the antenna performance of total radiation efficiency and mean effective gain (MEG).
