Planar antenna modeling requires a constrained solution space and open boundaries and so is highly computationally intensive. One of the methods used to overcome this is by using method of moments simulation. The method of moments is a highly efficient method of solving wire antenna structures and is commonly used in antenna optimization. A method of transforming a wire antenna structure to a planar antenna structure is presented using a 4-element Yagi-Uda antenna designed to resonate at 905 MHz. The wire to planar transformation is based on the circular cross section wire to planar strip, a spacing adjustment based on interelement capacitance, and a length scaling to compensate for the change in effective permittivity. The planar antenna shows slightly improved impedance performance at the resonance [voltage standing wave ratio (VSWR) 5 1.39]. This transformation decreased the antenna footprint by 15.11% after conversion for a wire antenna to a planar antenna in air with similar radiation characteristics and on FR4 (1.6 mm thickness), the footprint increased by 52%. The antenna simulation time was reduced from 15 min using finite element method to less than 10 s for one cycle by using the method of moments solver. All antenna properties are essentially unchanged.

“…The applications include, but are not limited to radar cross section (RCS) computations, antenna analysis, remote sensing, biomedicine, electromagnetic interference, and electromagnetic compatibility. Method of moments [1] based on electric field integral equations (EFIE) [2], magnetic field integral equations, and combined field integral equations (CFIE) is one of principal techniques used in the scattering problems. The formulation considered in this article is based on EFIE as it is applicable to both open and close surfaces.…”

“…In the last years, an important research effort has been carried out to develop new antenna geometries, mainly in printed technology, capable of offering multiband behavior. Dipole antennas, based on printed technology [1] and slot technology [2], are widely used for this purpose. Regarding commercial wireless applications, omnidirectional antennas are commonly preferred.…”

Microstrip printed antennas are the preferred choice in high data ratio modern communications, mainly at 2.45 GHz and above. In this paper, we propose two different approaches of microstrip printed antennas for lower frequency usage. In this sense, we present a printed microstrip Yagi-like antenna at 868 MHz and a printed dipole log-periodic antenna for wider band applications. We focus on the use of low-cost substrates, with a good performance at these frequencies, and giving antennas with useful sizes for such applications. For the analysis, we make use of standard experimental characterization combined with full-wave 3D-FDTD specifically developed simulations. In this way, the S11, radiation patterns, and gain/efficiency figures are given.
