Patch antenna size reduction by combining inductive loading and short-points technique

The present letter concerns the reduction of the size of a patch antenna by combining two techniques. Inserting slots as inductive loading and making some short points in the middle of a patch excited originally in the TM001 mode permits us to obtain an overall reduction of 75%. This enables the development of antennas for several applications, especially in portable communication systems requiring small footprint devices. © 2001 John Wiley & Sons, Inc.
