The ACA series offers a range of WLAN/Bluetooth and GPS antennas in a low profile (5.0 x 2.0 mm to 2.0 x 1.2 mm respectively), low cost, RoHS compliant and lead-free SMD package.
The ACA series of chip antennas is designed to cover WLAN bands at 2.45 GHz and 5.2 GHz and GPS bands at 1575 MHz, with impedance matched to 50-ohms in a low profile package, with a maximum height of 1.2 mm.
“The ACA series of chip antennas is highly compact and offer an efficient solution for applications where PCB area is critical. This is demonstrated by the ACA-102-T that offers one of the world’s smallest antenna volume of 2.4 mm3, measuring 2.0 x 1.2 x 1.0 mm, and yet has a peak 3D gain of 0.6 dBi and efficiency of 84%,” explains Dean Clark, Technical Sales Manager for Abracon.
The ACA-103-T offers dual band WLAN capabilities over 2.45 GHz and 5.487 GHz. This antenna is tuned and matched to operate in both WLAN/Bluetooth 2.45 GHz and 5 GHz WLAN bands simultaneously or through dual or single feeds from either band, depending upon the matching lumped elements. This device can be used in applications using IEEE 802.11a, b, g or n, and the new draft IEEE 802.11ac that will offer 8 x 80 MHz MIMO channels.
For GPS applications with highly constrained PCB space, the ACA-104-T offers a space saving 4.0 x 1.8 x 1.2 mm solution, while providing a +0.03 dBi peak gain and a typical VSWR of 2.0:1.
The ACA-101-T offers the compact design of a chip antenna measuring 4.0 x 2.0 x 1.2 mm, with WLAN capabilities of 2.45 GHz, a high peak gain of 1.09 dBi and a typical VSWR of 2.5:1.
Key features of the ACA series include:
- Impedance matched to 50-ohms with options for π, T or L-matching circuits.
- A -40ºC to +85ºC operating temperature range.
- An ultra compact, low profile design for high density surface mounting.
- High gain and efficiency.
- A dual band option for 2.45 GHz and 5.487 GHz applications.
