ABSTRACT:
Enhanced physical protection against vandalism for RFID reader/writer units is provided by a relatively thick metal front or housing which also functions as the antenna element of the reader/writer. The metal front is cut or slotted to define a radio frequency antenna integral with the metal front or housing for improved physical protection and good unshielded antenna function.
