How To Choose The Correct Antenna Variant
Refer to the table below for substrate thickness and the corresponding antenna variation.
PCB Substrate Thickness Recommended JTI PN
≤ 1.0mm 2450AT42E0100
1.0mm - 2.0mm 2450AT42E010 B
≥ 2.0mm 2450AT42E010 C
| Typical Efficiency Values @ 2.44GHz for various scenarios for a 30x50mm PCB
The following efficiency values represent performance on a 30x50mm EVB like on page 2. Please note that antenna
efficiency varies widely with board layout, size and surroundings.
PCB Simulated Antenna Efficiency(%) @ 2.44GHz
Substrate
Thickness 2450AT42E0100 2450AT42E010B 2450AT42E010C
(H)
H = 0.12 mm 1.95% 1.02% 0.93%
H = 0.7 mm 29.20% 9.30% 2.30%
H = 1.5 mm 23.30% 41.90% 13.80%
H = 2.5 mm 21.60% 34.20% 38.40%
We encourage you to use a relatively thick dielectric layer below antenna, as we have seen a direct
correlation between substrate thickness and antenna performance.
Note: "H" substrate thickness of <0.25mm (10mil) is not recommended. The component will still work and
radiate, just not optimally.
