A Study on Improving Impedance Characteristics of Planar Monopole Antenna with Vertical Ground Plane

摘要

This paper presents the improving impedance charactersitics of a planar monopole antenna with a vertical ground plane. For improving impedance characteristics, we used the effect of a vertical ground plane. To analyze the effect of vertical ground plane, we proposed the dipole antenna mode, the impedance characteristics of planar monopole antenna are improved by correlation between monopole antenna and vertical ground plane, based on each operating mode. Our analysis indicates can improve the impedance characteristics of varying planae monopole antennas. 【Keywords】 Planar monopole antenna, Vertical ground plane, Impedance characteristics, Wideband operation
