A New Solution for Car Parking RFID Reader

Abstract

In this paper, we present the design of a small antenna with bidirectional radiation pattern and high gain for RFID reader application. This antenna, which has a very simple structure, is composed of three pairs of S-shaped meander line. The antenna is designed, fabricated and measured to operate at the SHF band (2.4-2.485 GHz). The tested results are in good agreement with those of the simulations. The proposed antenna has the advantage of high gain of 7db in both directions with a volume equal to 106 mm ⨯ 19 mm ⨯ 0.9 mm, which makes it easy to integrate in RFID readers and a good candidate for RFID smart parking applications.
