We present a comparison of RF simulations with Ansoft HFSS and CST Microwave studio software, for a commercially available 7 T multi-channel coil. We investigated the conditions influencing precision and simulation time. When simulation parameters (such as mesh size) are appropriately selected and full coverage of the results is ensured, there is agreement between simulated and experimentally d...

MIMO techniques promise a significant boost in the capacity of wireless systems. In this paper, MIMO system is designed using a compact double-sided printed antenna having ultra-wideband and band-notched characteristic. The UWB antennas are designed on CST Microwave studio simulation software with return loss less than -10dB, and further using the results from CST, performance analysis of diffe...

Using the finite element method (FEM) in two dimensions and the CST MICROWAVE STUDIO (CST MWS) Transient Solver, the electromagnetic (EM) analysis and the design of a novel compact ultra wideband (UWB) bandpass filter using rectangular coaxial cables with square inner conductors, convenient for high power applications, are presented. The design of the UWB BP filter is based on the use of impeda...

In this study, we present the analysis and modeling of detailed investigation and study of different configurations of loop elements in FSS, with resonant unit cells. The elements studied are 1) Square loop, 2) Double Square loop and 3) Gridded Square loop. The simulations of microstructure are performed with full wave simulation tool CST Microwave Studio on single-substrate for different physi...

A Log Periodic Dielectric Resonator Antenna (LPDRA) for broadband applications is presented. In this paper, a broad bandwidth antenna is formed by application of log periodic technique to the series fed electromagnetically coupled rectangular overlaid dielectric resonator array. This Log Periodic DRA is simulated using a CST microwave studio suite 2010. The simulated results show wider impedanc...

A microstrip patch antenna for WLAN application is proposed. The antenna has a frequency bandwidth of 196 MHz (5103MHz 5300 MHz). The microstrip antenna has a planar geometry and consists of a ground, a substrate, a patch and a feed. The basic theory and design are analyzed, and simulation using CST Microwave Studio commercial software is employed to optimize the antenna's properties. Results s...

Nowadays, there are high demands on the transmission of visual information between devices. It is expected that the image will be transmitted at high speed and if it is possible at all times. The helical antenna designed in this paper works at the frequency of 5.820GHz for which are suggested standards for signal transmission. It is assumed to insert the product into Unmanned Aerial Vehicles as...

The mode-matching technique is deployed in this paper in order to analyze and design a substrate integrated waveguide (SIW) T-junction diplexer in Ku-band. The diplexer has bandwidths of 4.12% and 3.79% at 14.55 and 15.85 GHz, respectively. Also in Ku-band, an SIW corner filter is analyzed and designed with the same technique. Analytical results are compared with simulated data obtained from co...
