Abstract

Band pass filters are important components for RF/microwave systems providing a low insertion loss within the pass band and a large attenuation in the stop band .Recently; broadband band pass filters have drawn a lot of attention. The design of broadband microwave filter consisting of parallel-coupled lines usually has the realization problem of very narrow coupled-line gaps. In recent years, solutions especially related to broadband filter implementations have been studied in several literatures. In this paper we proposed Chipless RFID Multiresonators, fabricated with Accurate Attenuation and Complete until Fill until complete Mechanism. In AAFCM technique we assume the conductive material is filled into a mould with predefined dimensions. A chipless RFID transponder consists of a multiresontor connected between 2 tranceiving antennas. We present a new multiresonator loaded band-rejected planar monopole antenna for ultra wideband applications. Then we apply the concept of Non Redundant design procedure on that system so we can achieve much simpler and accurate synthesis in comparison to previous one.
