Abstract
A multiple-frequency stacked microstrip patch antenna structure is disclosed which provides substantially increased isolation between the multiple radiating elements and between the multiple feed elements. In one embodiment of the present invention having two radiating elements, such isolation is afforded by disposing shielding around a portion of the feed pin connected to the upper radiating element by electrically connecting the reference surface with the lower radiating element. Additional isolation and improved response characteristics can be provided by employing a tuning network for each radiating element. Additionally, two or more sets of stacked radiating elements can be arranged in an array to provide increased gain or directivity capabilities.
