Antenna Types and Material Selection
Antenna PCB design requirements vary significantly by type and frequency. The table below maps common antenna types to recommended materials and dedicated pages with application-specific specifications.
| Antenna Type | Frequency Range | Recommended Material | Dedicated Page |
|---|---|---|---|
| Single patch element | 1–40 GHz | RO4350B or RO3003 depending on freq | RF PCB Manufacturer → |
| Patch antenna array (76–77GHz) | 76–81 GHz | RO3003 0.127mm | 77GHz Radar PCB Manufacturer → |
| Phased array / beamforming | X / Ku / Ka band | RO3003, tight Dk uniformity | Phased Array PCB Manufacturer → |
| Ka-band satcom array | 26.5–40 GHz | RO3003 / RT5880 | Ka-Band PCB Manufacturer → |
| Wideband ESM/EW antenna | 2–18 GHz | RT5880 | EW PCB Manufacturer → |
| Feed network / power divider | Varies | Match to array material | Controlled Impedance PCB Manufacturer → |
Precision Requirements for Antenna PCB
Unlike general RF circuits, antenna elements are resonant structures — their physical dimensions directly determine operating frequency. Small variations in etch tolerance, Dk, or surface flatness shift the resonant frequency of every element on the board.
| Factor | Impact on Antenna Element | Riching PCB Control |
|---|---|---|
| Surface flatness | Patch dimensions vary with surface warp — shifts resonant frequency | ENIG standard — flat surface for dimensional accuracy |
| Etch tolerance | Patch edge variation shifts resonant frequency | ±0.01mm etch tolerance, ±20% on fine features |
| Dk tolerance | Element resonant frequency depends on Dk | RO3003 ±0.04 — tightest in PTFE range |
| Via fence placement | Affects element isolation and pattern shape | 0.4mm center-to-center, consistent across panel |
| Copper weight uniformity | Affects trace width and element edge definition | 0.5oz–1oz controlled per layer |
For array designs where element-to-element consistency matters — not just single-element accuracy — see phased array PCB manufacturer for panel-level Dk uniformity controls.
