PCB stripline antenna, strange design

[abcd567]

@jaymot

The original designer said “basée sur le principe de l’antenne colinéaire coaxiale” (based on the principle of the coaxial colinear antenna)

Yes, that was my conclusion even without seein the original designer’s rematks.

@abcd567

This PCB antenna is a flattened CoCo.
The two sides of the PCB antenna are two limbs in column 3 of this sketch

The wide strips shield the thin strips, just like the shield of a Coax. The thin strips therefore do not radiate, and just act as connection between wide strip pieces. The actual radiators are wide strips. The top piece of thin strip projecting above pcb is un-shielded and is therefore a radiator

This weekend I will prepare it’s computer model and run the simulation
