A toy for a video game may include an RFID tag, with an inductive antenna for receiving and transmitting signals. The inductive antenna may have a ferromagnetic core. Inductance of the inductive antenna may be selected such that tuning of the antenna is determined by the inductance of the antenna and input capacitance of an RFID semiconductor circuit of the RFID tag, with in some embodiments no tuning capacitors utilized. In some embodiments the input capacitance of the RFID semiconductor circuit is parasitic capacitance of the RFID semiconductor circuit. |
