As wireless communication applications require more and more bandwidth, the demand for wideband antennas increases as well. For instance, the ultra wideband radio (UWB) utilizes the frequency band of 3.1-10.6 GHz .In this paper we introduce a new multilayer microstrip antenna for ultra wideband applications. In order to achieve suitable bandwidth, the antenna size is fine for mobile application...

Parallel slotting technique is applied in both radiating patch and ground plane to achieve the size reduction of about 84%. Ansoft Designer V2 is emp...

This paper describes the analysis and design of a class of square spiral microstrip antennas for broad frequency band and multi-frequency operations by adding suitable tuning elements in a single structure. The simulation and modeling of these configurations have been done using Ansoft HFSS software. The resonant frequencies and dimensions are computed from the cavity model of square patch. The...

An overview of the magnetostatic field synthesis method, Variable Field Generation (VFG), and results from applying it to a test case to design magneto-plasma-aerodynamic (MPAD) devices to observe algorithm performance in the MATLAB programming environment are presented in this paper. The algorithm applied to this test case included integrating the Magnetostatic module of the finite element sof...

The following example compares the modelling results of a TQFP package given by the commercial tool Ansoft Maxwell Q3D and the tool Advanced Package Model provided by IC-EMC. Both software give models in terms of R, L, C lumped elements. An equivalent geometrical model is built under IC-EMC from basic mechanical data. Even if some differences exist between the geometrical models built with both...

Abstract: In this paper a new design of Microstrip antenna has been proposed. An Eshaped Microstrip Antenna has been designed and designed structure is simulated using Ansoft HFSS 11.1 software. Low volume and low profile configuration, easily mounted, light weight, low fabrication costs are the advantages of this antenna. Designed antenna can be operated in dual frequencies such as 5.1GHz and ...

The best way of gain enhancement can be obtained is from the array models, but there are some problems associated with array antennas. Mutual coupling losses, element spacing and design complexity are major concerns in the array antennas. The present paper deals with the performance characterization among the 2X2, 3X3, 4X4 array antennas. Rectangular patch array models are constructed and simul...

The mathematics and physics model of OCT (Optical Current Transformer) with a gapped magnetic ring is briefly discussed in the paper. And some proposals of how to select the magnetic materials and crystals and reduce the stress birefringence of the crystal are also put forward in the paper. Based on the above, an OCT with 1000 A rated current is designed by using the ANSOFT Maxwell tools.

Recently, millimeter wave applications are rapidly growing in modern high-speed and broadband wireless systems such as uncompressed HD-TV transmission, home link and radar for the collision prevention. In this paper, a NRD guide [1] fed dielectric lens antenna with high gain and low sidelobe characteristics is proposed for millimeter wave applications. The proposed antenna is designed on the ba...

Maxwell 3D of Ansoft software were used for this study. Ansoft’s solutions are based on a more general program using Maxwell’s equations. A simple analysis has been done for calculating the magnetic force interacted between two magnets of similar poles facing each other. The modeling in Anosoft has been described.
