PIFA 天线分析4.3. Numerical Analysis
In the previous section, an algorithm was developed that applies the Method of Moments (MoM) to wire antennas of arbitrary shape. The MoM algorithm, implemented using NEC4, was validated using data published in [5] for the Radiation Coupled Dual-L Antenna (RCDLA). Following validation, a model of the Dual Inverted-F Antenna (DIFA) was developed that ensures convergence of the numerical results to the correct answer. In this section, the MoM model developed in Section 4.2.3.2 is applied to study the design issues of the Inverted-F Antenna (IFA) and the DIFA. 4.3.1. The Inverted-F Antenna The Inverted-F Antenna (IFA) is a variation on the transmission line antenna, or bent monopole antenna, with an offset feed that provides for adjustment of the input impedance. The r
