  • Patent number: 5605506
    Abstract: An antenna for a wireless network is disclosed. The network includes multiple gaming machines such as slot machines or video poker machines located in an establishment. These machines communicate certain playing data (coin-in, coin-out data, etc.) to a central computer over the wireless network. Antennas for the gaming machines are located in a conventional candle on top of the gaming machine. Such candles typically contain one or more lights which when illuminated indicate a certain event such as a jackpot being hit. The disclosed antenna is unobtrusively located within a conventional candle structure so that from its exterior, a candle antenna appears to be a normal candle of the type typically used on gaming machines. However, interior to the candle antenna is an antenna capable of sending and receiving signals of a particular radio frequency band.
