Ribbon Beam Antenna for RFID Technology

The paper describes new concept o antenna for RFID technology. Antenna is locate lines to monitor tags situated on trains. Antenna w and it is fabricated by microstrip technology. Ant same mirrored parts having the same radiation p consists of three dielectric layers. The first laye radiation elements. The second layer is only construction and it sets optimal electromagnet radiating elements. The third layer has on its top s and on the bottom side a microstrip circuit us radiation elements feeding. Keywords—RFID, cosecant radiation pattern, r antenna, microstrip.
