摘要：

This article describes a small, low-profile linear antenna that is fed at the tip of a have-wavelength element to maintain the input impedance high with a metallic reflector at a position near the antenna. A CPW-like port at one end of a linear element yields a capacitive coupling with the metallic reflector resulting in a resistance of 50 Omega at the serial resonant frequency. Using this feed structure, a low-profile electrically small antenna using a Peano line antenna is presented. The antenna gain and radiation efficiency of this antenna is compared with those of a meander antenna with the same dimensions and feed structure. The radiation efficiency of the Peano line antenna increases by similar to 2 dB compared with that of the meander line at the 1-GHz band. Finally, the polarization parameters are presented.
