MICRO CHIP DUAL BAND ANTENNA

摘要

PURPOSE: A micro chip dual band antenna is provided to reduce the leakage current, increase a gain, and improve a standing wave ratio by using a feeding hole. CONSTITUTION: A micro chip dual band antenna includes the first patch(32), the second patch(33), the first radiative patch(34), the second radiative patch, and a feeding hole(36). The first and the second patches(32,33) are covered on both sides of a longitudinal direction of a dielectric(31). The first radiative patch(34) is covered on an upper surface of the dielectric(31) to the first patch(32). The second radiative patch is connected to the first patch(32). The first radiative patch(34) and the second radiative patch cross each other in zigzag. The feeding hole(36) is opened toward the front face of the dielectric(31) in order to connect the first radiative patch(34) to the second radiative patch.
