Summary:
Wireless communication technology has advanced rapidly. Along with it, mobile terminals have become smaller and advanced in recent years. For such reasons, mobile terminals have required multiband antennas for various applications of electrically small antennas with very small size to the wavelength. Introducing meander line is typical method to miniaturize antennas, and multi band antennas and electrically small antennas have been widely studied. An electrically small meander line antenna has been reported. This antenna is an electrically small antenna (ka < 0.5, k: wave number, a: radius of a sphere surrounding the antenna), and is formed with meander line on the same plane. Moreover, the antenna can easily control the impedance. However, this antenna has a single resonance and a narrow bandwidth. A multiband antenna with two elements of meander line has been reported. Two elements are on the same plane. So, the dimension of the antenna is large compared to the resonant frequency. Moreover, the antenna has wide bandwidth, and multiple resonances. In this paper, an electrically small layered meander line antenna with multiple resonances is presented. Simulated and measured results in S_11 and radiation patterns are discussed with good agreements
