I have designed a circuit board with a WiFi (2.4ghz, 50ohm) module and two integrated trace antennas on the PCB, designed per manufacturer design recommendations with pads for a "PI" filter for impedance matching the antennas to 50ohm impedance. I'm looking for a RF engineer who can select components (capacitors and inductors) for the PI filter and test the circuit boards with the proper equipment, a network analyzer. In the attached circuit board image, the PI filters are represented by C7, L1, C8 and C9, L2, C10. You'll note there is also a pad to shunt the antenna to a UF.L connector for use with an external antenna, I'm not too concerned about the external antenna. Please only bid if you have the correct equipment and experience with this type of wifi antenna tuning / impedance matching. Thank you.

dear sir i am an electrical engineer with more than 10 years experience in antenna design. i have designed more than 20 different types of antennas using HFSS and ADS. i can stimulate this setup in HFSS or ADS and can exactly tell you which inductor and capacitor values would be required for impedance matching. regards

Hey, Sir , I will be straight honest with you, this is my account and I'm bidding for my brother who is an electrical engineer (I'm specialized in telecommunication, programming, security...etc). He can an select components for the PI filter and test the circuit boards with a simulation software of your or his choice. I hope this fits your project needs. If chosen he will be directly contacting you. My best regards.

Hi. I have more than 20 years experience in the fields related to antenna/filters/wave propagation. Concerning your task I have experience with PCB trace antenna design and matching task for the TI C25xx (according to the corresponding TI AN043 Application Note). PCB trace antenna simulation, matching circuit components selection, tuning and testing are possible.
