Abstract

THE PRESENT INVENTION PROVIDES A FOLDED DIPOLE ANTENNA (100) CAPABLE OF TRANSMITTING AND RECEIVING SIGNALS FROM CDMA 450 SYSTEM. THE FOLDED DIPOLE ANTENNA (100) COMPRISES A FOLDED DIPOLE PRINTED CIRCUIT BOARD (PCB) (101) HAVING CONDUCTING STRIPS (106) DEFINED ON EACH SIDE OF THE FOLDER DIPOLE PCB (101) FORMING AN EXCITATION ARM AND A GROUNDING ARM OF THE ANTENNA, BOTH EXCITATION ARM AND THE GROUNDING ARM ARE ADAPTED WITH SYMMETRIC A CONDUCTING STRIP CONFIGURATION, WHEREIN THE CONDUCTING STRIP ON EACH SIDE OF THE PCB (101) COMPRISES AN M-SHAPED CONDUCTING STRIP HAVING A CENTER CONDUCTING LEG, AND TWO SYMMETRICALLY CONFIGURED FOLDED ARMS, WHEREIN THE CENTER CONDUCTING LEG IS THINNER IN WIDTH THAN THE TWO FOLDED ARMS; A PLASTIC HOLDER (103) WHEREBY THE FOLDED DIPOLE PCB (101) IS PLACED THROUGH; A BASE PLATE (104) WHEREBY THE FOLDED DIPOLE PCB (101) IS MOUNTED PERPENDICULARLY ONTO THE BASE PLATE (104) THROUGH THE PLASTIC HOLDER (103); AND A COAXIAL CABLE (102) HAVING A CENTER CORE EXTENDED THROUGH THE FOLDED DIPOLE PCB (101) TO CONNECT WITH THE EXCITATION ARM AT ONE END, AND A METAL SHIELD SOLDERED ALONG THE CENTER CONDUCTING LEG OF THE GROUND ARM, WHEREIN THE OTHER END OF THE COAXIAL CABLE (102) IS EXTENDING THROUGH THE BASE PLATE (104) WITH A CONNECTOR. (FIG. 1)
