In this article, a slot antenna is proposed to achieve both harmonic suppression and wide bandwidth. To obtain these results, a T‐shaped microstrip‐line‐fed slot antenna and U‐shaped conductor line connected with the ground plane are applied. At the fundamental and harmonic frequencies, return loss and radiation characteristics are measured and compared with those of the conventional slot antenna. For the proposed antenna, the 10‐dB return loss bandwidth could reach 1220 MHz (1730–2950 MHz), which is about 52% with respect to the center frequency of 2340 MHz, and it is observed that the second and third harmonics of the proposed antenna is effectively suppressed. © 2006 Wiley Periodicals, Inc.
