Dipole Antenna Printed on Paper Substrate for WLAN Applications

International audienceThe design of a dipole antenna printed on a paper substrate is presented in this paper. The antenna which integrates a compact balun is devoted for dual-band 2.4/5 GHz WLAN applications. The antenna is based on a double-side printed multilayer paper substrate and is fed with a coaxial cable for the testing. The simulated results of the whole structure are also presented in detail and compared with the measured performances

Implementing Wideband Monopole/Dipole Antennas on Paper Substrates

International audienceAdvanced internet and multimedia set-top boxes are today massively based on 4*4 MIMO systems, with multi-sub-bands standards (Wifi bands, LTE, Bluetooth,…). Multiple antennas spatially distributed on the plastic casing become therefore a great challenge for cost and performances motivations, thus promoting flexible technology and substrate, for assembling subsystems , under compactness considerations, as well as electrical performances improvement. In this paper, we discuss about the characterisation of Multi-band antennas designed on an ultra-low cost material (a cellulosic substrate, i.e. a paper) with design challenges in terms of radiation efficiency maximization and wideband properties under compactness constraints. Simulation and measurements are proposed to validate the designs

Characterization of Flex to Printed Circuit Board Interconnections using Insertion Connectors

International audienceAdvanced internet and multimedia set-top boxes are today massively based on 4*4 MIMO systems, with multi-sub-bands standards (WIFI bands, LTE, Bluetooth,…). Interconnections between the numerous access ports of different radio chipsets mounted on a main PCB (Printed Circuit Board) and multiple antennas spatially distributed on the plastic casing become therefore a great challenge for cost and performances motivations. The flex technology, based on well-controlled and low cost process, brings new functionalities and opportunities for assembling subsystems , under compactness considerations, as well as electrical performances improvement. In this paper, we discuss about the characterisation of connectors used for flexible printed circuit to a main PCB interconnections. The choice of the connectors is a critical issue, and must be properly done considering both local ground and signal interconnections constraints. Simulation and measurements are performed up to 15Ghz covering WIFI bands
