Designing BT Antenna for RFID Systems
نویسنده
چکیده
This paper is about designing and optimizing a new antenna employed for RFID applications at microwave frequencies. The structure is designed in a way that it resonates at 2.45GHz, which is one of the RFID frequencies. The new patch is derived from BT(Bow-Tie) antenna. It results in a reduction of the size by more than 70%, as compared to monopole patch, alongside with having an acceptable gain and directivity. Based on a model of triangular antenna, a correspondent resonant model is presented. Simulation results achieved using our method show that the antenna and its model have the same resonant frequency at 2.45GHz. However, there was a little difference in Bandwidth.

A compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
