Strong experience in RF, Microwave, Antennas, and millimetre-wave design (CST, HFSS, Agilent ADS, AWR Microwave design, MATLAB, LabVIEW, Cadence, Xilinx, spartan. FPGAs) MATLAB skills in signal processing, 5G, 4G, Machine Learning, deep learning, computer vision, RF toolbox, Antenna toolbox, Analog and Digital electronics, Radar systems, Internet-of-things, RTOS, Embedded systems, C, C++, Python, NumPy, pandas, sci-kit learn, TensorFlow, PyTorch, OpenCV. I am an Electronics Engineer, professional RF designer, python developer, and technical writing specialist. I got educated in Sweden, Finland and Pakistan & worked in Sweden, Belgium and Pakistan. I can work on Radiofrequency and microwave projects and write technical reports for you, from literature reviews, research, paper reviews, simulations, tabular comparisons of the latest papers and referencing/formatting in Latex/Word with high-quality results. The tools I use are Agilent ADS, AWR Microwave office for RF Circuit design (Low-Noise Amplifiers, High Power Amplifiers, Mixers, VCOS), CST, Antenna Magnus, Altair Feko and HFSS in array antenna designs for 5G, loT, satellite/radar/vehicular applications. I can use Python for data analysis, such as numpy, pandas, Tensorflow, data manipulation and feature extraction, and matplotlib/seaborn for plotting CSV, json, XML and popular data formats. I can do data cleaning, feature scaling and extraction, I can work on building Machine learning models from training, train/test/validation splitting, and getting results such as accuracy, precision, recall, and ROC, on methods such as K nearest neighbours, SVM, Random forest, PCA, dimensionality reduction, ensemble methods, stochastic, minibatch, batch gradient descent, ridge, lasso regression using datasets: I can help in procuring equipment/RF/Electronics from Asia, china, specifically RF equipment, amplifiers, attenuators, RF Microwave PCBs, and dielectric materials such as rogers replacements. More and more 5G components are coming from ZTS. I can write high-quality technical reports from academics, MS/PhDs and content writing. I am a researcher by profession & can write Journal/conference papers with high-quality results. Consult me for IEEE papers writing, academic paper writing or Electronics & Radiofrequency design projects. I develop Internet-of-things solutions, MQTT, CoAP, HTTP, Websocket, /Application Layer protocols, AWS loT, GCP, D2D solutions, wired (UART, SPI, I2C) and wireless (Zigbee, RF, Bluetooth, NB-loT, LoRawan, Sigfox, Zwave, 3G/4G. GSM, Wi-Fi, WLAN), esp32, esp8266, dragonboard410c, Arduino mini/mega, raspberry pi, Restful API, edge AI devices, Real-time operating systems (RTOS) & microcontroller based embedded solutions.I can write for blogs/websites on the advanced and latest hardware topics such as GPUs, advanced displays etc and advanced topics in RF, electronics and AI/ML engineering.

Design and Size reduction analysis of microstrip hairpin bandpass filters

Hig Diva Hogskolan i Gavle
The thesis work presents the design of Microwave filters in S-Band with a fractional bandwidth of 10% and size compactness. First, a 5th-order HBPF is presented with an FBW of 12%. Consequently, 4th and 3rd Order filters are also presented with FBW achieved up to 3% and a considerable size reduction. The thesis work presents the design of Microwave filters in S-Band with a fractional bandwidth of 10% and size compactness.
