PCB Trace Antenna Review and Optimization for EM4325 IC

I am seeking a skilled professional to review and optimize an existing PCB trace antenna design, specifically for the EM4325 IC. The project involves addressing performance issues, including limited reading range and angle sensitivity, while ensuring the following:

- Detailed Review: Analyze the current PCB trace antenna design for potential improvements.
- Optimization: Redesign or adjust the PCB to enhance performance, particularly in terms of reading range and angle sensitivity.
- Shape Variations: Provide two shape designs for the PCB to explore different form factors. Provide two different overall PCB board shape designs/form factors incorporating the antenna design, to explore different physical board configurations.
- LED Connection Fix: Correct a missing LED connection in the current design.
- Testing: Deliver a fully tested and verified working solution that meets all specified requirements.

Ideal Skills and Experience:
- Expertise in PCB design and optimization for RFID systems, particularly with EM4325 ICs.
- Strong background in RF systems and wireless communication.
- Experience with troubleshooting and testing PCB antennas for optimal performance.
