Abstract

A compact broadband microstrip antenna with DGS in the range from 2 to 7 GHz for wireless communication applications is proposed. The proposed broadband antenna is designed at the operating frequency of 4 GHz and simulated using TLM model and HFSSv.15, respectively. Wireless standards like WiMAX (3.6 GHz), Hi-LAN (5.15-5.35 GHz), WLAN IEEE802a (5.2GHZ) and DSRC (5.850-5.925 GHz ) lie in this frequency range. The proposed broadband antenna with compact dimension of 32 x 22 x 1.6 mm3 is fabricated on FR4 dielectric material having εr of 4.4 & tanδ of 0.02. S11, VSWR & bandwidth for the proposed antenna are measured. The bandwidth with S11 less than -10 dB is measured as 3770 MHz in the frequency range from 2.70 to 6.47 GHz. Peak gain of 5.22 dBi and radiation efficiency of 90- 98% are achieved for frequency at 6 GHz. The radiation patters at different frequencies are found to be stable. Comparisons between the simulated and measured results for the proposed antenna show a close agreement. The fabricated broadband antenna has been also compared with the earlier designed antennas indicating its nobility and better performance.

紧凑型宽带微带天线与DGS无线应用

提出了一种适用于无线通信的2 ~ 7ghz DGS小型宽带微带天线。设计了工作频率为4ghz的宽带天线，并采用TLM模型和HFSSv进行了仿真。分别为15。WiMAX (3.6 GHz)、Hi-LAN (5.15-5.35 GHz)、WLAN IEEE802a (5.2GHZ)和DSRC (5.850-5.925 GHz)等无线标准都在这个频率范围内。所提出的宽带天线尺寸为32 × 22 × 1.6 mm3，采用εr为4.4,tanδ为0.02的FR4介电材料制作。测量了天线的S11、驻波比和带宽。在2.70 ~ 6.47 GHz的频率范围内，S11小于-10 dB的带宽测量为3770 MHz。在6 GHz频率下，实现了5.22 dBi的峰值增益和90- 98%的辐射效率。发现不同频率的辐射模式是稳定的。该天线的仿真结果与实测结果的比较表明，仿真结果与实测结果非常吻合。并将所制作的宽带天线与早期设计的天线进行了比较，表明其性能优越。
