Abstract
In this paper, a single zero compensation dipole antenna for WLAN frequency band is designed. The antenna can be suspended above the space and the radiation range can cover the whole space below. The antenna is fed by the parallel transmission lines, and the radiation unit consists of a printed dipole antenna and a Yagi antenna. The printed dipole antenna is printed on both sides of the FR-4 dielectric substrate with relative permittivity of 4.3. The printed dipole antenna adopts complementary symmetry structure to optimize the non-roundness of H plane. The driver arms of the Yagi antenna are printed on both sides of the substrate, while the director and the reflector of the Yagi antenna are located in the dielectric substrate to compensate the zero point of the dipole antenna. The simulation results show that the VSWR of the antenna is less than 2 in the 2.32-2.45 GHz band. The maximum directivity is more than 1.8 dBi in the 2.322.45GHz band. The non-roundness of the H plane of the antennais less than 2dB,which shows good omni-directivity. A zero point in the radiation pattern of the E plane is compensated, and it is -1.68dBi at 2.36GHz,0.62dBi at 2.4GHz and 0.48dBi at 2.44 GHz, respectively, while the other zero point of the E plane remains below -12 dBi in the working frequency range, namely realizing the function of single zero compensation.
