Abstract
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 0.1464Ξ»~g~ Γ 0.1789Ξ»~g~ at the cutoff frequency 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. Β© 2006 Wiley Periodicals, Inc.

## Abstract In this letter, the compact coplanar designs of the microstrip antenna are performed to suppress the harmonic radiations. The antennas with the secondβorder harmonic suppression as well as the secondβ and the thirdβorder harmonic suppressions are designed, respectively. The results indi
## Abstract This paper describes an efficient design method for an apertureβcoupled microstrip patch antenna, based on an improved transmission line model. The governing equations have been derived and applied to the design of the antenna with a center operating frequency of 11 GHz. The theoretical
## Abstract This paper shows that, by using the current density distribution on a patch, the positions of shorting pins and slots can be determined so that the unwanted modes are suppressed. An example of applying this technique to a rectangular patch to suppress the second and third harmonics is p
## Abstract We investigate the directivity, sidelobe level (SLL) and maximum radiation angle characteristics of a frequency selective surface (FSS) superstrate placed above a 5 Γ 1 patch array antenna for different scan angles. We find that the frequency at which a high directivity is achieved move
