✦ Synopsis

Abstract

A defected microstrip structure (DMS) is proposed to reducing the size of a rectangular patch antenna by increasing its electric length, without degrading its performance. To illustrate this advantage, one conventional and one proposed defected patch antenna were developed and measured at 1.77 GHz. The simulated and measured results concerning the radiation patterns and bandwidth of both antennas are very closely related, but the proposed defected antenna achieves 22% of total‐area reduction. © 2004 Wiley Periodicals, Inc.

## Abstract The present work establishes the use of the defected microstrip structure (DMS) as a novel method of tuning the central frequency of rectangular printed antennas. The error obtained from the predicted operating frequency and the measured one is less than 4%, without degrading the VSWR,
