Abstract

This paper is under in-depth investigation due to suspicion of possible plagiarism on a high similarity indexThis paper presents design and implementation 2-way Wilkinson power divider at 9400 MHz frequency which matched to 50Ω transmission line. This design applies Microstrip line with Roger Duroid 5880 Substrate and uses software simulation (ADS 2011) to help the design. This Wilkinson power divider designed at 9400MHz for use on Antenna X-Band Radar System. The desire objective is a power divider can be used in compact circuit board with low insertion loss and good matching for all ports. The dimension of the devices after fabrication is 30mm x 35mm. The voltage standing wave ratio (VSWR) for all port for both dividers is less than 1.33,  Forward transmission the devices as divider or the split power ratio (S21 and S31)is about -2.522dB, reverse transmission the devices as combiner (S12 and S13) is about -2.861dB. The isolation between the both output ports shows a good isolation, less than -11.271dB. The overall result of simulation and fabrication show a fairly good result.

Abstract

Short range radar (SRR) uses the K-band frequency range in its application. The radar requires high-resolution, so the applied frequency is 1 GHz wide. The filter is one of the devices used to ensure only a predetermined frequency is received by the radar system. This device must have a wide operating bandwidth to meet the specification of the radar. In this paper, a band pass filter (BPF) is proposed. It is designed and fabricated on RO4003C substrate using the substrate integrated waveguide (SIW) technique, results in a wide bandwidth at the K-band frequency that centered at 24 GHz. Besides the bandwidth analysis, the analysis of the insertion loss, the return loss, and the dimension are also reported. The simulated results of the bandpass filter are: VSWR of 1.0308, a return loss of -36.9344 dB, and an insertion loss of -0.6695 dB. The measurement results show that the design obtains a VSWR of 2.067, a return loss of -8.136 dB, and an insertion loss of -4.316  dB. While, it is obtained that the bandwidth is reduced by about 50% compared with the simulation. The result differences between simulation and measurement are mainly due to the imperfect fabrication process.
