Abstract :
This paper presents measured antenna impedance and patterns of a horizontally oriented folded dipole as it is moved toward a metal ground plane. The 915 MHz measurements on different antennas provide rules-of-thumb for RFID link design and suggest that changing antenna thicknesses may make tags more resistant to on-object degradations
