Investigation into Techniques for Packaging Cosite Microstrip Patch Antennas into Handheld Devices

In many situations, it is advantageous to have multiple wireless systems located in very close proximity to one another. Placing the antennas of separate systems near each other, however, creates numerous problems. In order to limit the severity of the issues associated with cosite antenna configurations, the antennas should be very well isolated. The following work investigates a few possible approaches to help isolate two nearby linearly polarized microstrip patch antennas on a common ground plane.
