Problems solved by technology
Furthermore, an inductive charging unit requires large coils in both devices (i.e., the charger and the device being charged by the charger), which may be undesirable due to size and cost, for example
Therefore, if it is not properly positioned on the inductive charging pad, the electronic device may not charge adequately or may not receive a charge
Also, if the electronic device does not charge as intended after using the charging mat, users may become frustrated, detracting from the credibility of the charging mat

A system is disclosed that includes: an RF circuit configured to generate an RF signal; a plurality of unit cells configured to receive the RF signal and such that RF energy having a center frequency is present in at least one of the plurality of unit cells a signal; and a receiver circuit configured to, in response to the antenna receiving the RF energy signal when the antenna of the electronic device is tuned to the center frequency and within a near-field distance of one or more of the plurality of cells, Charge electronic devices.
Description
technical field [0001] In general, the present disclosure relates to wireless charging. More specifically, the present disclosure relates to low power near-field charging surfaces. Background technique [0002] Electronic devices such as laptops, smartphones, portable gaming devices, tablets, etc. require electricity to operate. As is generally understood, electronic devices are typically charged at least once a day, or more than once a day in high-use or power-hungry electronic devices. This action can be lengthy and can be burdensome for some users. For example, if a user's electronic device lacks power, the user may be required to carry a charger. Also, some users need to find an available power source to connect to, which is time consuming. Finally, some users must plug into a wall or other power source to be able to charge their electronic devices. However, such action may render the electronic device inoperable or immovable during charging. [0003] Some conventi...
