A compact microstrip antenna with meandering slots in the ground plane

A novel compact microstrip antenna design is demonstrated. By embedding mea ndering slots in the antenna's ground plane, it is observed that the resona nt frequency of the microstrip antenna is significantly lowered, which can lead to a large antenna size reduction for a fixed frequency operation. In addition, enhanced impedance bandwidth and antenna gain are also observed f or the proposed antenna. Details of the proposed design and experimental re sults of the constructed prototypes are presented and discussed. (C) 2001 J ohn Wiley & Sons, Inc.
