Abstract: Various embodiments of the present technology generally relate to wireless power transmitter and antenna configurations for transmitting wireless power to one or more clients. In some embodiments, the wireless power transmitter includes boards having multiple antennas (i.e., an Antenna Matrix Board(s) (AMB)). The antennas can be on one side of each AMB board, while the control and power circuitry are on the reverse side. The antennas emit electromagnetic (EM) radiant energy that the client(s) receive, store, and/or use for communication with the charger or for the client device battery charging process. The antenna boards can be arranged in a configuration to increase (e.g., optimize) the amount of power transmitted to client(s). In various embodiments, the boards are arranged in polygonal shape as individual flat panels physically coupled to a support structure and attached to the CCB by plug in multiple pin connectors unique in mechanical design.
