Jason abc7e3c66b sim(antenna): center 1x8 row dip on radar TX 10.520 GHz (CONN_LEN 8.0->8.15) ...

Sweep CONN_LEN at PROFILE=balanced to land the operating-mode dip on the
chirp-band center instead of 60 MHz above it. Sensitivity is df/dCONN ≈
-0.20 GHz/mm (longer line → lower op freq).

  CONN=8.00 → dip 10.560 GHz, S11@10.520 = -12.6 dB (above TX)
  CONN=8.15 → dip 10.520 GHz, S11@10.520 = -18.8 dB (TX-centered)
  CONN=8.20 → dip 10.510 GHz, S11@10.510 = -18.4 dB (TX low edge)
  CONN=8.25 → dip 10.500 GHz, S11@10.500 = -18.4 dB (LO-centered)

CONN_LEN=8.15 wins because the radar TX 10.510-10.530 GHz sees -17 to -19 dB
symmetrically across the band, with -15 dB margin at the LO frequency. -10 dB
BW spans 10.470-10.580 GHz (110 MHz). Pitch 15.10 mm vs old Gerber 15.01 mm.
