A novel filter-based power divider for wireless communication in intelligent transportation systems

Popis výsledku v původním jazyce

Intelligent Transportation System (ITS) is a modern technology aiming to improve traffic management and modes of transport. The Long-Term Evolution (LTE) standard is a suitable protocol for wireless communication systems in new ITS applications due to its high speed capacity. In this paper, a novel H-shaped filtering Wilkinson Power Divider (WPD) is proposed using H-shaped resonators at LTE standard and frequency of 1.8 GHz. Firstly, a compact LPF with simple structure is designed at 2.2 GHz cut-off frequency. The proposed LPF has a wide stop band from 2.85 GHz up to 8.16 GHz with more than 20 dB attenuation level, while the stop band can be considered from 2.5 GHz up to 20 GHz with more than 10 dB attenuation level. The results show that the measured insertion loss is less than 0.5 dB, the input and output return losses are more than 16 dB and 22 dB, while the ports isolation is higher than 17 dB at the main frequency. The proposed divider can correctly work at a 480 MHz bandwidth, which is corresponding to more than 25% fractional bandwidth. Furthermore, the harmonic suppression up to the eleventh harmonic is achieved for the proposed divider. The obtained measured results proved the efficiency of the proposed component.
