Antenna Optimization Service
Orderable Part Number: ABAOS-5WK
Abracon offers in-system tuning services for patch and chip antennas. By directly testing antenna coupling gain and center frequency in the end system, this service takes the guess work out of RF verification while offering corrective measures that retune the system. This provides maximum system efficiency delivering many benefits including extended RF range, improved sensitivity and may reduce the required power consumption for a given level of transmit range.
This service is offered for the APAE and APA series of passive patch antennas covering a variety of RF bands from 800MHz to 6000MHz including applications such as RFID, GPS/GLONASS, WiFi, ISM radios, and Iridium. Patch antennas are compact with excellent coupling gain and are easy to use. However exact tuning may depend on layout and the design of the ground plane. If de-tuned center frequency or gain is discovered during testing, a new patch antenna design can be constructed based on the existing one but with adjustments that match the layout for maximum gain at the center frequency of the application.
This service also applies to the ACAG, ACAJ and AMCA series of chip antennas. Chip antennas such as the ACAG-0201-2450-T with 2.0x1.25mm footprint are ultra-compact with good gain that increases sensitivity for applications such as Bluetooth, Bluetooth Low Energy (BLE), WiFi/WLAN, and Zigbee. They require a matching pi-network that optimizes antenna impedance thereby improving the efficiency. For chip antennas, the antenna must be tuned to the center resistant frequency, by matching the input impedance using lumped elements like inductors and capacitors. Higher efficiency guarantees more radiated power and increased range for antennas.
The test requires a fully functional system to be shipped to Abracon and typically takes 4 weeks to complete.
