Abstract— The microstrip patch antenna is a printable resonant antenna with distinguishing features such as integration, good radiation control and low cost of production. Thus it can use in a wireless linked application such as RFID. In this paper, the microstrip patch antenna is designed simulated for two frequencies of 5.6GHz and 5.8GHz using HFSS (High Frequency Structure Simulator) software which can be used for active and passive antenna.
Keywords— Microstrip, RFID, HFSS.
I. INTRODUCTION
The advancements in wireless technology given birth to radio frequency identification (RFID), which creates a significant interest among the scientists, researchers and industry. RFID technology can be used for identification, location and transferring of information using radio waves. It also reaches its application in areas of logistics, manufacturing, transportation, health care and mobile communication. Basically the RFID system consists of tag or a transponder and a transceiver or reader. The tag is combined with the application of integrated circuit chip (ASIC) which is activate and detect the tag. The transceiver or a reader transmits a modulated signal with periods of unmodulated carrier.
The microstrip patch antenna falls into the categories of printed dipole, slots and tapered slots on the basis of distinguished features including ease of integration, good radiation control and low cost production. Due to the antennas resonant style radiator so one of the dimension isλ⁄2 where λ is the guided wavelength of surrounding environment of printed antenna. The shape of the patch antenna is one of the factors of resonant dimensions. The dielectric constant ε_r of the substrate and its height depends on the antenna performance. One of the major advantages of the patch antenna is its size is relatively small comparator to other radiators. The minimal thickness of the substrate of the microstrip patch antenna make it easily integrated into the skins of the various objects.
Due to significant performance and cost advantages due to its light weight, low fabrication cost, and the ability to fabricate feed lines and matching networks simultaneously with the antenna structure, integrating microstrip patch antenna with RFID can achieve.
