Abstract


The microstrip antenna is an antenna with a conductor connected to put on the floor of the dielectric substrate and conductor sheet is formed . It has a low profile, light weight, can be used with a variety of carriers conformal ; feed network can be printed together with the antenna , suitable for mass production of printed circuit technology ; easy to achieve circular polarization , dual polarized , dual band and other advantages. Developed from the the seventies initial microstrip antenna , microstrip antenna has been extensive research and development , and access to a variety of applications , and in the broad field of microwave antennas , as a discrete whole set up their own subject. This paper to verify the U-shaped groove one for Bluetooth and WLAN load the H-type patch dual-frequency microstrip antenna , double effect is achieved by a single-layer microstrip antenna , while significantly reducing the size of the antenna , to achieve a small and requirements . Papers using Ansoft's HFSS v10 software simulation study on the design of the antenna . The results show that the dual-frequency antenna has a good resonance characteristic, the center frequencies are 2.24GHz and 5.25GHz , the bandwidth in the VSWR = 2 , completely covers the two bands . The paper also has done a detailed analysis of the performance impact of the the antenna main parameters of the antenna . In the final , made ??of the need to solve the problem .
