**Me TECH** · Antennas · 1206

ANT321612042G4A from Me TECH, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | passive | Ground-side terminal; connects to the PCB ground plane in the recommended 5.2 × 5.0 mm clearance-area layout. |
| 2 | FEED | passive | RF feed terminal; connects to the 50 Ω transmission line through the suggested matching network (1.1 nH series inductor, 1.0 pF shunt capacitor) over 2400-2500 MHz with 50 Ω impedance and ≤ −6.5 dB return loss. |
