Machine body antenna
First Claim
1. A communication system for communicating with near field devices using a machine body antenna, the system comprising:
- an RF receiver element and an RF transmitter element forming an inter-communicating RF transmitter and receiver pair, and a machine body antenna cooperating therebetween, a near field device in electrical communication so as to cooperate with a first element of said transmitter and receiver pair, wherein said machine body antenna is electrically isolated from ground and includes an electrically conductive machine frame electrically connected to so as to cooperate with and be excited by a second element of said transmitter and receiver pair, and wherein said first element is within a near field of said machine body antenna without being in contact with said machine body antenna

Abstract
A communication antenna for communications with a near field device using at least one transmitter and receiver pair, wherein the antenna includes a machine body antenna which is electrically isolated from ground and includes an electrically conductive machine frame, and which, when in electrical communication with one transmitter or receiver element of the transmitter and receiver pair, is excited so as to enable communication between the transmitter and receiver pair when the other of the transmitter or receiver elements is in electrical communication with the near field device and mounted within the near field of the machine body antenna without being in contact with the machine body antenna.
