A Review on Reconfigurable Low Pass Bandstop Filter Based on Technology, Method and Design
Reconfigurable filter technology is in robustness development. Due on the tunable and reconfigurable capability will contribute a various advantages in wireless applications. This tuning selectivity consist a numerous method, for example using varactor, micromachines, and PINdiodes. In this paper, the authors discussed PIN diodes as a switching element. The design and development of different types of switching element were then described. This paper presents of reconfigurable low pass bandstop filter WLAN, UWB bands applications for the past few years that operatedbetween1 to 5.6GHz. Most of the studies were focus on Chebyshev filter because of the excellent selectivity and the response is easy to be analyzed.
