Question: What are  C1, C3, C4, L1 , L2 elements mean in the wiggle antenna design provided in CY3630 kit?






- C1 provides DC blocking.




- C3 provides impedance matching.


- C4 provides harmonic notching.

- L1 is the RF choke, self-resonant at 2.45 GHz.

- L2 provides power combining with 180 degree phase phase shifting and impedance matching.
