Hi I am an Electrical Engineer with extensive experience in RF&Microwave circuits design and development. I can provide lumped components values and exact model for the 50 ohm matching circuit. I use Keysight ADS for smith chart matching I have a National Instruments Vector Network Analyzer and will provide you with all the S_parameters before and after matching. 1. I'll be needing the PCB physically with me in Pakistan, and the gerber file for the antenna+PCB 2. It will take me a month to provide you with final matching circuit 3. Please share more details on the component you want matched 4. Bid is negotiable Looking forward to a detailed discussion and i have to see the PCB design for evaluation. Best Regards Usman
