Abstract

A filter-antenna configuration for the application for UWB communication system is presented. Firstly, a microstrip transmission line fed monopole antenna for the wide-band (2.65 GHz-8.52 GHz) communication system is designed and Its performance is verified. Secondly, in the place of microstrip transmission line feeding, a planar UWB microwave filter is used and the performance (3.65 GHz-10.16 GHz) of the new filter-antenna configuration is noted. The new filter-antenna configuration considerably improves the antenna performance and wide-band antenna becomes the UWB antenna after the insertion of the UWB microwave filter in place of microstrip-line feeding technique. Hence, the UWB antenna can be used as the wide-band impedance matching circuit to enhance the performance of the antenna in the passband. Apart from this there is improvement in the out-of-band performance. The proposed UWB filter-WB antenna configuration is simple and compact in size providing broadband impedance matching, and consistent radiation pattern within the UWB frequency range.

一种结合超宽带微波带通滤波器的宽带单极天线，用于超宽带通信系统

提出了一种适用于超宽带通信系统的滤波天线结构。首先，设计了一种用于宽带(2.65 GHz-8.52 GHz)通信系统的微带传输线馈电单极天线，并对其性能进行了验证。其次，在微带传输线馈电的基础上，采用平面超宽带微波滤波器，并对该滤波器-天线结构的性能(3.65 GHz-10.16 GHz)进行了分析。新的滤波天线结构大大提高了天线的性能，在插入超宽带微波滤波器取代微带馈线技术后，宽带天线变成了超宽带天线。因此，超宽带天线可以用作宽带阻抗匹配电路，以提高天线在通带内的性能。除此之外，带外性能也有所改善。所提出的UWB滤波器- wb天线结构简单紧凑，在UWB频率范围内提供宽带阻抗匹配和一致的辐射方向图。
