High performance normal mode helical antennas for RFID tags
A 0.035 wavelength very small normal mode helical antenna is designed to achieve high antenna efficiency. Antenna gain of -3.72dBd is achieved. When this antenna is attached on a metal plate, antenna gain is increased to -0.4dBd. Communication distances of current RFID tags and NMHA tags are measured. In the case of NMHA tags, communication distances comparable to current RFID tags are ensured.
