“…The system is composed of a reader (Interrogator) and a battery powered ASIC type active tag (Active sensor tag) each equipped with an antenna serving the purpose of both transmitter and receiver simultaneously with the help of duplexers (An antenna duplexer or RF duplexer is a unit that can be used to enable more than one transmitter and receiver to operate on a single RF antenna [15]) as shown in Fig. 1.…”

An analytic approach is presented to evaluate the Bit Error Rate (BER) and detection range of an active RFID network using space diversity technique both at the reader and the tag receiver. The analysis is carried out with battery powered Application Specific Integrated Circuit (ASIC) type RFID tags for a UWB system with different up-link and down-link frequency ranges. Single Input Multiple Output (SIMO) configuration is used to communicate between the reader and the tag. Maximal Ratio Combining (MRC) technique is used for diversity reception. BPSK, QPSK and M-ary PSK (MPSK) are considered with coherent demodulation to evaluate the BER performance. The results are numerically evaluated and it is found that with the application of the receiver diversity there are significant improvements in BER performance and the maximum detection range achieved with 5 receiving antennas is 920m at the BER of 10-08. The maximum improvement in detection range at the same BER with same number of receiving antenna is found to be 361.10m. The analyzed approach gives a clear insight regarding the interrelationship between BER, detection ranges,reader received power, number of receiving antenna, order of modulation and detection range improvement and has given improved performance in detecting tag at a comparatively longer distance in outdoor non line of sight (NLOS) environment.

An analytic approach is presented to evaluate the Bit Error Rate (BER) and read range of a UWB chipless RFID network using diversity technique at the reader receiver for Rayleigh fading over the channels. The analysis is carried out with multiresonator based chipless RFID tags for a UWB system of frequency range from 3GHz − 6GHz and bandwidth of 500MHz in an outdoor and farm non line of sight (NLOS) environment. SISO configuration is used to communicate from reader to tag and SIMO configuration is used to communicate from tag to reader. Maximal ratio combining technique is used in the reader for diversity reception of the tag. BPSK, QPSK and M-ary PSK are considered with coherent demodulation to evaluate the BER performance and a read range of 548.00m at the BER of 10 −06 could be achieved. The analyzed approach not only gives an improved result compared to the previous research works but also gives a clear insight regarding the interrelationship between BER, detection ranges, reader received power, number of receiving antenna and read range improvement.

“…From the literatures, several examples can be found in certain designs such as antenna [3][4][5][6], filter [7][8][9], switch [10][11][12], mixer [13] and low noise amplifier [14], [15]. Besides, the demand has also led to the challenge in RF and microwave circuit design to support the requirements of different frequency bandwidths for different bands.…”

In this paper, a design of hybrid microstrip diplexer is proposed for multiband Worldwide Interoperability for Microwave Access (WiMAX) application in 2.3 and 3.5 GHz bands. The diplexer consists of a combination of two different filter designs. These filters were designed based on microstripline coupling techniques in order to obtain minimum insertion losses and achieve the desired frequency bandwidth. Therefore, a coupled open loop ring resonator was chosen for the filter design in 2.3 GHz band and a folded coupled line resonator was chosen for the filter design in 3.5 GHz band. Then, these filters were combined with a ring manifold matching network to be a hybrid microstrip diplexer. Based on the results, good agreements were achieved between the simulation and measurement results in terms of insertion loss, return loss and bandwidth in the 2.3 and 3.5 GHz bands.
