The finite-difference frequency-domain (FDFD) method is a very simple and powerful approach for rigorous analysis of electromagnetic structures. It may be the simplest of all methods to implement and is excellent for field visualization and for developing new ways to model devices. This paper describes a simple method for incorporating anisotropic materials with arbitrary tensors for both permi...

To evaluate the electromagnetic power absorption in near field, the magnetic composites with the conductive grids were simulated using the typical permeability frequency profiles. The transmission power absorptions of the magnetic composites on microstrip line were extracted by the 3D FEM simulation program of HFSS. The magnitudes of power absorptions were greatly enhanced up to 98% and broaden...

A novel design of Dual band pyramidal serrated microstrip patch antenna was designed and Simulational results are presented in this paper. Equal spaced serrated pyramidal shapes are etched on four sides of the patch and its performance characteristics are simulated using commercial software HFSS. The current model is resonating at dual band with moderate gain. Return loss, radiation patterns, i...

3D printing and printed electronics are combined to demonstrate the feasibility of printing electrically functional RF devices. A combined process is used to demonstrate the feasibility of fabricating a 2.4 GHz antenna in a fully-3D printed object. Both dielectric, which also serves as the structure, and conductors are printed. Full-wave models are generated using Ansoft HFSS. Real-world tests ...

The paper presents the design of a novel ultra-wideband microwave crossover for the use in microstrip circuits. The proposed structure includes a double microstrip-coplanar waveguide (CPW) vertical interconnect in single-layer substrate technology which allows an inclusion of a finite-width coplanar waveguide (CPW) on the top side of the substrate to achieve the required cross-link. The present...

The coplanar waveguide (CPW) fed microstrip patch antenna considered in our work. This design results in a reduction in size and weight and al...

This paper presents a multiband folded loop antenna for smart phone applications. The proposed antenna with a symmetric loop pattern generates four resonance modes in the design bands. The current distributions of the excited resonance modes are analyzed to confirm the mode characteristic. Using a pair of tuning elements near the feed port, the impedance bandwidth is broadened to cover GSM850/G...

This paper focuses on the EM modeling of an inkjet printed humidity sensor for UHF RFID systems originally presented in [1]. EM modeling is used to predict the sensor readings as well as to design the tag for certain operating frequencies. Therefore accurate EM modeling is crucial. This paper presents a comparison between three different types of EM solvers in modeling of the humidity sensor; A...
