ABSTRACT:
An apparatus and method for tuning a multi-radiating element embedded microstrip antenna is disclosed. In one embodiment, the lower resonant frequency of an antenna is tuned using trimmable tabs integral with an upper radiating element and/or scrapable recessed edges on the ground plane surrounding the upper element and/or trimmable tabs interconnected with the ground means and extending inwardly towards the upper element.
