Reverse-engineered and modeled supplier antennas (conformal, array, cavity slot, spiral, sinuous) using CST, HFSS, and FEKO and integrated models onto AV for analysis of installed farfield radiation patterns and coupling between antennas. Supported UCLASS for Payload and Communications aircraft installed antenna performance and co-site analysis. Modeled phased array transmit and receive antenna gain using Matlab antenna gain plugin script in STK as a function of air vehicle (AV) body coordinates. Used STK to model BLOS communication link performance for forward and return link via TDRSS satellite. Link dropouts and link margin as a function of look angle and attitude rate. Used STK to model access to Iridium LEO constellation from (a) fixed ground location (b) aircraft to determine Modeled antennas and analyzed as-installed antenna performance.

EVALUATE FIELD ON A CURVE CST MICROWAVE STUDIO SOFTWARE
Expert is proficient in use of software simulation tools for satellite system and RF design, including Satellite Tool Kit (STK), Matlab/Simulink, SPW, Agilent Advanced Design System, Eagleware/Genesys, AWR Microwave Office and Visual System Simulator, CST Microwave Studio, and Ansoft HFSS. Expert has performed RF/microwave system level design of payloads and transceivers, including cascade analysis of linear, intermodulation, thermal and phase noise distortion, dynamic range, intercept point, gain and noise figure link budget analysis, and Bit Error Rate performance. Expert performed end-to-end modeling/simulation and requirements analysis for the MUOS mobile satellite system, which uses a Wideband CDMA waveform based on the 3GPP standard. Expert worked on a 60 GHz point-to-point radio development where he designed the coplanar waveguide antenna with hemispherical anti-reflection ceramic shell and performed the system design including modulation, spectral and filter analysis, modulation index (FSK), spectral emissions mask and specification of filters. These are constructed with around the curves, with a radius of a/10 around each curve.Expert has 20+ years in the RF/antenna/communications engineering field, including design of RF solid-state power amplifiers, airborne radar warning receiver systems, wideband satellite receivers, payload engineering, end-to-end satellite communication systems analysis/simulation, waveform development (M-PSK, M-QAM). These structures have the same material properties as the background material (vacuum) and ensure a finer mesh generation in this region.
To allow the mesh to be redefined within the mesh limitations of the CST Studio Suite Student Edition, dummy structures are introduced surrounding the current paths and along the z-axis (Fig. It is also helpful to have a dense mesh surrounding the current paths. In Table 1 we summarize all the parameters of this project.įor the evaluation of the field values along the curve one has to ensure that adequate interpolation points are available. The microstrips must be realized on a substrate with ε r=4.3, a thickness of 1.2 mm and a metallization of 0.035 mm.
