Numerical analysis of the radiation characteristics of the meander line antennas consisting of two strips

FDTD Characterization of Meander Line Antennas for Rf and Wireless Communications

“…The changes in impedance and resonant frequency are observed by increasing the number of segments of the meaner line trace gradually until the design goal is achieved. In [2][3][4][5], meander line antennae have 50 Ω input impedance when they are measured on a large ground plane or in dipole configuration. When the meander line is printed on a small substrate sitting on a small ground plane as shown in Figure 1, the input impedance reduces dramatically.…”

“…possibility of applying PCS for military purposes are considered, then antenna designs for wireless personal communication systems should be expanded in scope to cover the frequency range from the current 0.9-2.0 GHz to 0.9-3.0 GHz range. In this paper, studies for the characteristics of a printed meander line antenna [1][2][3][4][5], using the finite difference time domain (FDTD) techniques [6] with Berenger's perfectly matched layers (PML) absorbing boundaries [7] are presented. The presented designs of the antenna shown in Fig.…”

“…The presented designs of the antenna shown in Fig. 1(b), feature small dimensions (77 × 11 × 3.17 mm 3 ), approximately 50 Ω input impedance, dual frequency operating in the 0.9-3.0 GHz band, and on a comparably small ground plane (59 × 25.4 mm 2 ) . One of the validations of the numerical code used in this investigation is made by comparing the numerical results of the return loss of a rectangular printed patch antenna with the computed and measured data reported in [8,9].…”

Design optimization of chip antennas using the GA-FDTD approach

“…By using a ceramic base with a higher dielectric constant than that of air, the equivalent wavelength g is shorter in the base than in free space. One can wrap the monopole antenna around the base to shorten the total length of antenna; thus, the size of the antenna can be reduced efficiently [9,10]. As mentioned above, although the length of the monopole antenna can be reduced via meandering, the physical characteristics of the meandered antenna need to remain the same in terms of function.…”
