2 in 1 leakey coaxial cable for intrusion detection sensor

Novel leaky coaxial cable (LCX) is developed. It contains both transmitting and receiving LCX for intrusion detection sensor. While the suppression of coupling between transmitter and receiver is major theme in microwave technology, we give a solution of transmitter and receiver antenna combination. We have developed a prototype of 2 in 1 LCX and then evaluated its performance for intrusion detection sensor in field experimentation.
