Source
Resonant inductive charging is a form of wireless power transfer that maintains high system efficiency across mid-range distances due to the 'Q', or quality, of the antennas. The transmitter (Tx) or wireless charging product generates a safe electromagnetic field that is captured by a receiver (Rx), which is a small accessory that plugs into a device's power port. The antenna quality is the barometer for the antenna's intrinsic efficiency or its inductive reactance divided by its resistance. The higher the intrinsic 'Q', the more potential coupling between the Tx and Rx, which in turn leads to more power being delivered to the device at a further distance.
Unique High 'Q' Antenna Designs & Production Methods
Industrial Antenna
Through proprietary quality control and production methods, we have developed the highest 'Q' antennas in the industry. The first generation MotherBox has measured antenna
'Qs' above 400, and our automotive antennas
have measured 'Qs' above 1100. This allows
us to greatly extend the charging distance for various applications, especially in comparison
to a wireless charging pad.
3D Arrays
We can alter the shapes and sizes of our antennas for various parts and products,
making our high 'Q' antenna solution
flexible and adjustable. Furthermore, we
can create multiple antenna arrays to
guide the magnetic fields to your devices
in three-dimensional space.
Dynamic Amplifiers
Our amplifiers have an ability to withstand a wide range of reflections. In other words, they can adjust in real-time to both the movement of devices and to the introduction of new devices into the charging field.
Inductive charging like never before.
Today, resonant inductive charging is mainly limited to wireless charging pads. Since the antennas in wireless charging pads have low 'Q', typically between 50 and 100, the pads cannot charge devices very far.
Furthermore, even if the charging pads had higher 'Q' antennas, the amplifiers would struggle to charge devices for variable or unpredictable movement because they are designed for a specific impedance or placement of devices on top of the charging pad.
Our high 'Q' antennas, 3D arrays, and amplifier developments give us the ability to charge devices at significantly further distances and more dynamically than ever before.
