We present the development and performance evaluation of wearable passive UHF RFID tags based on slotted patch antennas that are electromagnetically optimized for operation in the close proximity of the human body. The antennas are manufactured from an electro-textile material on a light-weight textile substrate. The required patch-toground interconnections(More)
We present the comparison of wearable passive UHF RFID tags based on dipole and patch antennas made of textile materials. The tags’ wireless performance was evaluated when attached to the upper back of a test subject. Despite the fundamentally different structures and electromagnetic operation mechanisms of the antennas, both tags attained read ranges of(More)
