VIKRAM DHARMRAJ

A building professional having knowledge of different aspects in RF & microwave electronics, currently working in Research and Development area. The scope of my work to antennas design, fabrication and measurement of antennas i.e. radiation pattern, gain, etc in anechoic chamber and open region. The analysis of radar cross section (RCS) for various electrically large size platforms is done on HFSS, CST and FEKO with different solver while comparison with standard measured object i.e. NASA almond. The placement of antennas on different platform to realize it various parameter is done with multiple methods and different solver, to get exact analysis of component stand alone and with platform. The placement of antenna mostly called masking studies, which helps to generate electronics results for normalizing the performance of any component on board for final flight.

Previously, I worked in DRDO labs on project where I design various types of antennas and in that one antenna is selected for on board application. The novelty of antenna was circular polarization with dual band for satellite communication system. The single antenna will work for two bands of microwave frequency(s) in both polarizations i.e. RHCP & LHCP for Tx and Rx. The final antenna is low profile and design efficient for desired application. The simulation and measured results of antenna are matched properly which shows the reliability of antenna for practical implementation.

During my academic time of post graduation, I designed various microwave components like filter, coupler, waveguide, microstrip to waveguide transition, power divider, etc. All design components are extracted in CAD tools for fabrication purpose and material assignment. The basic knowledge of EMI and EMC testing also acquire during this spam time. In the anechoic chamber, I measured various antennas with VNA. 

I am confident that if given an opportunity, I will be definitely fulfilling your expectations on the professional front end
