ACADEMIC PROJECTS:

RF/Microwave Design and Measurements (Laboratory)

Software: EM simulator in AWR –MWO and AXIEM Hardware: Vector Network Analyzer, Power meter etc

Gained experience working in RF/Microwave Design and Measurements laboratory and designed components like resonators, Wilkinson Power Divider, Directional Coupler, Filters, Microwave Amplifier in AWR –MWO and AXIEM.

Fabricated the designs on Duroid 5800 and FR-4 substrates

Return loss, insertion loss, gain and power were measured using VNA, Spectrum analyzer, Power meter, Signal generator etc

Also designed Microstrip patch antenna and did EM simulation of radiation patterns in Elevation and Azimuth

Using iFilter wizard in MWO, designed Microstrip edge coupled Chebyshev band pass filter

Design of two stage Amplifiers (RF Amplifier Design)

Software: AWR-MWO and Matlab

Low Noise Amplifier

Designed a 2-Stage LNA at 10 GHz with N.F<2dB, Gain>18dB and R.L>10dB

Gain and Noise Figure were calculated, matching networks and bias networks were designed

Also performed Stability and Performance analysis for the designed amplifier

Broadband RF Amplifier

For a two stage broadband amplifier with the specified parameters, DC analysis was performed to ensure that the transistor was properly biased to operate in linear region. AC analysis was performed for frequency range. Stability analysis was then made to ensure that amplifier doesn’t oscillate in the specified frequency range. Impedance matching was done using lumped elements. The S - parameters, noise figure and gain was also calculated using AWR MWO

Simulation of Path loss models and OFDM implementation according to IEEE 802.11 and LTE standards (Wireless)

Software: Matlab

Developed Matlab program to perform path loss simulations for models like Free space model, Simplified path loss model, 2-Ray ground reflection model and Cost 231 model. Also calculated cell coverage and BER using Matlab

Calculated BER for BPSK, QPSK and 16-QAM modulation schemes

Simulated physical layer of OFDM system for QPSK and 16QAM as per LTE and IEEE 802.11 standards

Simulation included BER Vs SNR and Spectral efficiency plots

Lightning Predictor System using RADAR and Satellite Communication (RF Systems Design)

Software: AWR –MWO

Designed a radar and satellite system to predict a lightning event and predetermine its striking location and time in Microwave Office. This system can guide a lightning power tapping station to tap power effectively.

RADAR reflectivity, Doppler shifts from cloud contents and wind turbulence were taken into consideration for determining the point of lightning discharge

Designed 35 GHZ Polarimetric Doppler RADAR system and a Ku band Satellite communication system for this purpose. Parameters like RCS, MDS, antenna gain etc were considered

Calculated Cascaded gain, Noise figure, Power added efficiency and performed Yield analysis

Peer Review of IEEE Journal paper (RF Circuits)

Unequal Wilkinson Power Divider using coupled lines with two shorts

Software: AWR –MWO

Simulated unequal Wilkinson Power Divider using coupled lines with two shorts using AWR Microwave Office. This type of coupled line implementation proved to be helpful in realizing high impedance small width lines which are very difficult to fabricate using conventional methods.

When implemented using coupled lines, line width of each line is increased corresponding to the change in impedence

Image Processing Tools in Android (Image Processing)

Software: Java (Eclipse IDE), Android SDK

Developed methods for Image Smoothening, Histogram Equalization and Median Filtering in java

Implemented those methods in android SDK and presented with a GUI

Numerical solution to Laplace’s Equation (Fields and Waves)

Software: Matlab

Implemented a Matlab project to solve Laplace’s equation for a given geometry and modeled the performance of a capacitor

Voltage and Electric field at all the points inside the specified geometry were calculated

DTMF transmitter and receiver system (DSP)

Software: Matlab

Designed a DTMF transceiver system that works well for very low values of SNR and also implemented a GUI for the same using Matlab
