Resonant frequency and radiation efficiency of meander line antennas

Abstract

One of the approaches to reducing the size of half-wavelength linear dipole antennas is the meander dipole antenna, where the elements form a meander line. This paper presents a formula for the relationship between the geometrical size and the resonant frequency of the meander line dipole antenna, and a calculation formula for the radiative efficiency is derived from the result. It is shown that the geometrical parameters of the meander line dipole antenna can be determined from the specified radiative efficiency. © 1999 Scripta Technica, Electron Comm Jpn Pt 2, 83(1): 52–58, 2000
