Abstract
In this paper, we proposed a broadband planar Yagi-Uda dipole antenna with dual tapered balance and unblance (balun) by CPW-fed to CPS. This antenna consisted of driver, three directors, dual tapered balun and CPS-fed to CPS. The fed structure of CPW-fed to CPS had a benefit points much simpler than other planar Yagi-Uda antennas and provided design more flexibility in arranging the reflector. The proposed antenna is introduced dual tapered balun to improve the impedance matching. It balun is inserted between the CPW-ground and the CPS. The proposed antenna is exhibited the bandwidth of 4.78 GHz (1.94~6.72 GHz) (S11 < -10 dB) and the gain of 4.9~7.2 dBi within that bandwidth. This antenna will applicate wireless communication.
