The combination of a near-field coupling antenna placed in the central area of a UHF RFID desktop reader with a low-gain resonating antenna allocated at the reader border is here proposed to obtain a confined detection volume within the antenna near-field region (including both the reactive and radiative near field regions). The antenna layout consists of a spiral Travelling Wave Antenna (TWA) which series-feeds an array of two circularly-polarized miniaturized patches. The spiral TWA geometry… CONTINUE READING
