Abstract :
This paper presents an analysis of three types of antennas for backscatter radio reader and a method for measuring backscattering signal from antennas which involves using a network analyzer connected to an anechoic chamber with and without the receiving antenna. We analyzed the backscattered signals of two types of dipole: wire dipole at the operating frequency 1.8 GHz and microstrip dipole operating frequency of 900 MHz. The experimental results showed that the receiving antenna dipole wire showed a better reflection of the backscattered signal compared to the microstrip dipole. The dipoles presented higher gain than broadband microstrip antenna, can be a good options for backscatter radio reader.
