Elements in Wiggle antenna

Version 1
    Question: What are  C1, C3, C4, L1 , L2 elements mean in the wiggle antenna design provided in CY3630 kit?

     

    Answer:

     

     

     

    - 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.
