This letter presents a slot‐coupled microstrip patch antenna with harmonics suppression capability within an enhanced bandwidth. Measured return loss result at the operating frequency, second harmonic frequency, and third harmonic frequency were 22.2 dB, 1.77 dB, and 1.93 dB, respectively, with a 9% impedance bandwidth around 2.45 GHz. The antenna is a good candidate for further integration with class‐F amplifiers. © 2007 Wiley Periodicals, Inc.
