Abstract
This paper presents a novel method to suppress the
higher order harmonics in the microstrip patch antennas. A practical
0.75 GHz microstrip patch antenna is fed with a quarter-wave feedline
designed by exploiting the dispersion properties of shunt-capacitor-
loaded transmission-line metamaterials. It is shown that two higher
order harmonic modes at 1.25 and 1.5 GHz are completely eliminated.
In addition, there is about a one-fourth reduction in the length of the
impedance matching quarter-wave feedline
