This paper examines the concept of using an array of holes in a substrate for antenna performance improvement. The finite‐difference time‐domain (FDTD) numerical technique is used to demonstrate the utility of the concept. The results clearly show the substantial radiation performance improvement of printed antennas by lowering/controlling the effective dielectric constant of a substrate by perforating it with an array of holes. © 1998 John Wiley & Sons, Inc.
