MASTERS IN ELECTRICAL ENGINEERING Dear client After reading through your project it matched my skills and since its within my field of expertise and my preferred area of interest. I will cover all required guidelines comprehensively to meet your expectation and give outstanding results. I hereby request you consider my bid for quality work and we discuss further on deliverables.

Hi dear I am an electronics engineer and i have experience of circuits designing. Share your project details further I will provide you my best service. Thank you

Hello, I am an electronics and teleocommuncation engineer any my major is wireless systems' design. So far I have designed many antennas and their related parts such as matching circuits, filters(distributed/lumped), power dividers, power amplifiers, phase shifters, etc.. I have also used varactor diodes for tuning matching circuits and a patch antenna. So I am quite sure that ı can help you with your project. Can I use CST Microwave Studio Suite, AWR Microwave Office or Keysight ADS? Let me know. Best regards

i am Antenna design engineer for satellite and telecommunications antenna with experience of 2 years. i have recently designed pifa antenna with varactor diode. i can easily design your antenna if you give me specifications. it will be honoured working with you

I had a research experience of 3 years in antennas and active antennas using Ansys HFSS. As per your requirement, you need the design of antenna with varactor diode. I will check the datasheet of the desired varactor diode and I will know the equivalent circuit of the diode. Then I will design the antenna and place the equivalent circuit in the design such that we can get the result. I am assuring you that I will give you the quality work with in less time.
