Abstract

A rectangle patch antenna with U-notch is a practical method to improve the bandwidth of microstrip antennas bandwidth. If special material substrate and add matching network are combined, which not only reduce the quality factor of antenna, but also produce maximum output power for little reflection of load. When the dielectric constant ε of special material substrate changes, the bandwidth of U-notch microstrip patch antennas is different. The impact of dielectric constant is discussed in detail. The S11 parameter of the antenna has been simulated by HFSS. The simulation results show that the lower dielectric constant can gain wider band of antenna.
