Abstract :
The design of circularly polarized microstrip patch antenna (MPA) with wide axial ratio beamwidth working at 2.4GHz band is proposed. The wide axial ratio beamwidth is achieved by a 45° rotated slot cut in the center of the square MPA. By placing two back-to-back MPAs on intelligent door lock, the function of indoor-outdoor recognition has been successfully realized.
