Abstract
In this paper, a tetraband microstrip patch antenna with defective ground structure (DGS) is proposed. DGS structure is used for improving the performance of microstrip patch antenna. The proposed structure shows the multi-frequency band operation and it covers S and C-band frequencies that are allocated by FCC for TV transmission and reception with open satellite communication. This antenna is designed on FR-4 substrate with dielectric constant 4.5 and thickness 1.8 mm and its size is 40 X 35 X 1.87 mm3. The return loss, gain and directivity of proposed structure is analyzed using commercial computer simulation technology microwave studio (CST MWS). The simulated results show the close agreement with proposed theory. The main application of proposed antenna is to make compatible with open satellite communication for free (not scrambled no subscription required) satellite services.
提出了一种带有缺陷接地结构的四带微带贴片天线。采用DGS结构提高微带贴片天线的性能。所提出的结构显示了多频段工作，它涵盖了FCC分配的S和c频段频率，用于开放卫星通信的电视发送和接收。该天线设计在介电常数4.5、厚度1.8 mm的FR-4衬底上，尺寸为40 X 35 X 1.87 mm3。利用商用计算机仿真技术微波工作室(CST MWS)对该结构的回波损耗、增益和方向性进行了分析。仿真结果与所提出的理论基本一致。该天线的主要应用是兼容开放的卫星通信，提供免费(不加扰，无需订阅)的卫星服务。
