Introduction In this project, a portable FMCW-interferometry radar is designed and built, whose operation frequency is at the 5.8-GHz. This radar system can be configured either in the FMCW or interferometry mode by means of an on-board micro-controller. This design features low-cost and portable. Experiments were carried out to reveal Read more…
Introduction This project aimed at the realization of a single 24-GHz radar transceiver chip with Global Foundry 0.13 µm CMOS process. Using a CMOS process instead of a GaAs process in K-band can lower the cost, which is one of the very important factors for radar applications in consumer electronics and Read more…
Introduction In this work, a 16 x 4 quadrature polarized horn array was designed for satellite communication. This array has 12.5 GHz and 14.25 GHz bands, each band has 500 MHz bandwidth. Design This array and its feeding network were designed with CST Microwave Studio. Some parts of this design Read more…
This was the project for my Master Thesis. Some parts of the project have been published in IEEE Antennas and Wireless Propagation Letters and IEEE Transactions on Microwave Theory and Techniques. Introduction In this work, a new concept “complex domain” radio frequency (RF) frontend is proposed, the relatively slowly changed Read more…
Introduction This was a team project which aimed to evaluate the possibility and performance of a RF signal generator built with off-the-shelf components. This project has both the hardware the software. The hardware part includes a frequency synthesizer, filter array, modulation circuit, power controller and micro-controller. The software part includes Read more…
