ABSTRACT:
The invention provides a PCB type dual band patch antenna and a wireless communication module incorporating the antenna. The antenna includes a substrate. A ground pattern is formed on the substrate. A radiating patch is formed on the substrate to be spaced apart from the ground pattern at a predetermined distance. The radiating patch includes an input arm and a main radiator which are divided by a slot with ‘L’ and inverse ‘L’ shapes combined. The main radiator has an open terminal opposing the input arm across the slot. Also, a feeding part is connected to the input arm of the radiating patch to apply an electrical signal to the radiating patch. Further, wireless devices are integrally mounted on the PCB substrate used for the antenna, thereby achieving a high efficiency and wide-bandwidth dual band patch antenna and a minimal-sized and low-cost wireless communication module.
