Symmetrical small trapezoid dipole antenna for broadband wireless communications

抄録

This letter proposes the symmetrical small trapezoid dipole antenna for lower distorted radiation patterns. For broadband communication, a non-uniform planar antenna has been proposed; however, the radiation pattern at the high-frequency band is distorted. When the cell area is designed, it becomes difficult to design the directivity due to distortion of the radiation pattern. To overcome this issue, this letter proposes the symmetrical small trapezoid dipole antenna, which has the same dimension conductors at the opposite angle. The electromagnetic field simulation results evaluate that the proposed antenna has a small deviation of the radiation patterns at the high-frequency band.
