The magnetrons used in microwave ovens operate on the same frequency band as Wi-Fi equipment, and the radiation they release can interfere with the operation of wireless networks. This paper presents a multiphysics simulation of a magnetron using CST STUDIO SUITE®, with the aim of testing the electrical, magnetic, thermal and mechanical characteristics of a low-interference magnetron design. Th...

This paper reports on an experimental investigation of modes propagating along a conductor-backed slotline: the dominant mode, and the surface leaky mode. The measurement and the numerical experiments performed in the CST Microwave Studio verify theoretical findings of modes obtained by the method of moments applied in the spectral domain. The dispersion characteristic of the dominant mode on t...

A simple, small, compact, low cost, and practical antenna for 2.4 GHz applications is proposed in this paper. A detailed investigation on miniaturized microstrip planar antenna design using a combination of proposed shorted patch and meandering method are presented. All design and simulations are done using Computer Simulation Studio (CST) software. For accuracy reasons, verification has been d...

Abstract—This paper presents a novel design of a microstrip fractal antenna based on the use of Sierpinski triangle shape, it’s designed and simulated by using FR4 substrate in the operating frequency bands (GPS, WiMAX), the design is a fractal antenna with a modified ground structure. The proposed antenna is simulated and validated by using CST Microwave Studio Software, the simulated results ...

Here we report numerical results on the window-frame SIS-100 injection device at GSI. Details about the computational approach and definitions of the longitudinal (Z||), horizontal (Zx) and vertical (Zy) impedances can be found in Refs. [1, 2, 3, 4] and references therein. We merely remark that the modeling and discretization were carried out in CST MICRO WAVE STUDIO ®[5], whereas the simulatio...

In this paper, we have simulated a single-pin-shorted microstrip line fed three-dielectric-layer (with different permittivity and thickness) rectangular patch microstrip antenna for all those communication systems whose limited antenna size is premium. Low permittivity hard foam has been used as one substrate to achieve wide bandwidth. The simulation of this proposed antenna has been performed ...

The paper presents the design and fabrication of a H-plane substrate integrated waveguide (SIW) horn antenna. The antenna operates at 60 GHz band and is equipped with a SIW-to-WR15 transition. Experimental results prove that the antenna achieves the gain of 11.5 dBi and the impedance bandwidth of 14 % for the reflection coefficient less than -10 dB. The antenna was designed with the help of CST...

This paper shows the design of a fractal patch antenna, which uses a unique fractal geometry known as Pythagoras tree with co-planer waveguide (CPW) feeding. The antenna has been designed for dual band operation at the WLAN/WiMAX (2.4 GHz) and WiMAX (3.5 GHz) for ultra-wide bandwidth applications. The antenna was simulated using CST Microwave Studio. The fabricated antenna’s measurement results...
