A method and apparatus for providing a broadband near field of an antenna are disclosed. A small broadband loop antenna may include a printed circuit board (PCB) substrate with multiple layers. Printed on the PCB substrate are dual loops sharing a same driver circuit, an impedance matching network, a primary ground layer and a conductive layer. A shorting via connects the dual loops to a ground plane. The antenna may be tuned to a desired operating frequency by adjusting parameters of the loop, such as the position of the shorting via. |
