The quasi-Yagi printed dipole antenna is composed of the dipole and reflector as shown in Figure 1. The two arms of the dipole are printed on each side of a CuClad substrate of thickness 0.8 mm and permittivity of 2.17 (to overcome the complicated feeding technique). We use a microstrip line combined with a bifilar printed line. The length of these arms and the distance between them and reflector are around quarter-wavelength (λ0/4). λ0 is the wave-length in free space corresponding to resonant frequency around 2.45 GHz.
