Abdita Antenna for 2.4 GHz Band Applications

Antenova’s Abdita miniature antenna for 2.4 GHz applications is simple to integrate into a design and operates on various GND plane sizes. Abdita utilizes a ground plane to radiate efficiently in 2.4 GHz applications such as Bluetooth®/BLE, Wi-Fi (802.11a/b/g/n), and Zigbee®. It offers longer range connectivity than most ceramic antennas due to its higher efficiency of 60.5%. The enhanced design significantly improves antenna efficiency when compared to a trace on the PCB.

Abdita has an overall size of 1 mm x 0.5 mm x 0.5 mm. It fits on PCB as small as 50 mm x 30 mm and requires a 7 mm x 7 mm clearance area. It features an operating temperature range of -40°C to +125°C and a peak gain of 2.8 dBi with an average gain of -1.9 dB. It has a maximum return loss of -13.0 dB and a maximum VSWR at 1.6:1.

Resistant to de-tuning effects means devices can work well in different environments. Abdita operates with other antenna types nearby (good coexistence). Suitable applications include small wearable devices, headsets, medical devices with Bluetooth/Wi-Fi, satellite and personal navigation devices, and wireless sensor networks. The tape-and-reel packaging makes it suitable for high-volume manufacturing.

The Abdita antenna has a companion evaluation PCB (SRCW090-EVB-1) available for in-house testing.
