摘要：

Harmonic suppression is an important factor for active microstrip patch antennas radiating harmonic frequencies. Here, a novel compact low pass filter (LPF) having high filter selectivity and wide stop band is used on the microstrip feed line of the patch antenna. The 15 dB LPF stopband exist over 10 GHz while implementing area is 0.1464 lambda(g) X 0.1789 lambda(g) at the cutofffrequency of 3.55 GHz. The fundamental antenna operating frequency falls in the passband of the LPF. The other harmonics falls in the LPF stopband and thus attenuated. An example shows up to fourth harmonic are suppressed while total occupying area remains compact. (c) 2006 Wiley Periodicals, Inc.
