Abstract

This article demonstrates an alternative way of controllable resistive loading in microstrip patch antenna in order to increase its bandwidth. As microstrip patch antenna is a high Q structure, thereby narrow bandwidth, resistive loading (introducing lossy lumped element inside the antenna structure) is considered as potential technique for improving bandwidth. Instead of conventional resistive loading i.e placing resistance of desired value across the substrate an alternative technique of resistive loading is proposed. Here resistances are connected across the slots of microstrip patch antenna. This method of resistive loading is easy and controllable. Resistive loading is performed on a dual slot rectangular microstrip patch antenna. Behavior of the loaded structure for different resistance values and different slot positions has been studied. A significant improvement in the bandwidth of slotted microstrip patch antenna has been achieved at the expense of gain. This antenna is designed to operate in the frequency range of (2.4/2.5GHz) which partially covers WiFi and WiMax frequency range.

具有可控带宽的电阻负载开槽微带贴片天线

本文介绍了一种可调电阻加载微带贴片天线的方法，以提高其带宽。由于微带贴片天线是一种高Q值结构，因此带宽较窄，因此电阻加载(在天线结构内部引入有损集总元件)被认为是一种有潜力的提高带宽的技术。代替传统的电阻加载，即在基板上放置所需值的电阻，提出了一种电阻加载的替代技术。在这里，电阻通过微带贴片天线的槽连接。这种电阻加载方法操作简单，可控。对双槽矩形微带贴片天线进行电阻加载。研究了不同电阻值和不同槽位下结构的受力特性。以牺牲增益为代价，大大提高了微带贴片天线的带宽。该天线设计工作在(2.4/2.5GHz)频率范围内，部分覆盖WiFi和WiMax频率范围。
