Aircraft cabin-integrated 57-64GHz WLAN communication system

Abstract

This paper reports for the fi rst time on a novel 57-64GHz point-to-multipoint WLAN system, which is installed into an aircraft cabin mock-up. All the system components, from the RF-chip-set, the LTCC-integrated antennas and modules, to the baseband and application software were specifically developed for this application. In addition, the integration of these system components into a passenger aircraft cabin mock-up (ceiling and seat-integration) as well as successful system performance tests were carried out.

“…Besides, dual-mode resonators are mostly used in multiband bandpass filter design. One of the most popular design methods is to combine dualmode resonators having different electrical lengths under appropriate coupling [2][3][4][5].…”

“…Conversely, using the same impedance formulas, calculations of perturbation capacitance and gap capacitance between the feedline and the resonator are also given in [5,6]. In this study, dual-band filter design has been achieved using two stacked ring resonators as in [2][3][4][5]. However, these studies do not include the frequency response for dual-band characteristics.…”

“…Because of that, researchers as well as aircraft manufacturers have shown strong interest in the development of wireless systems for on‐board use. Focusing on applications within the cabin, there are a wide range of wireless technologies which are used for a broad range of applications, with different systems used depending on the final intended use, for example, wireless multimedia networks for in‐flight entertainment , deployment of wireless local area network communication systems , pilot health monitoring by means of wireless sensor networks , and sensing and monitoring.…”
