Description
ILA.257 is a compact LTCC chip antenna designed for next-generation Wi-Fi 6 and Wi-Fi 7 devices requiring tri-band coverage in a single, space-saving antenna element. Its surface-mount form factor and tight manufacturing tolerances support reliable RF performance and efficient automated assembly.
- Tri-band Wi-Fi coverage: supports 2.4GHz, 5GHz, and 6GHz (Wi-Fi 6E/7 band)
- Compact chip format: ideal for space-constrained embedded designs
- Stable performance: built for consistent operation across a wide temperature range
Typical applications include:
- Consumer Electronics
- Automotive and Transportation
- Wearable Technology
- Medical Devices
- Networking Equipment
Installation / Environmental
The following is an example on how to integrate the ILA.257 into a design. This antenna has 2 pins, where one pin is used for the RF Feed. The manufacturer recommends using a minimum of 30x40mm ground plane (PCB) to ensure optimal performance.
