Integrated Antennas on MnM Interposer for the 60 GHz Band

Abstract

In this article, antennas for the 60 GHz ISM band designed to be integrated to a new high-frequency, low-cost interposer technology called Membrane-nanowire-Membrane (MnM) are discussed, manufactured, and measured. Also, an antenna characterization system under development at the Microelectronic Laboratory (LME-USP) is introduced, showing promising results for the deployment of mmW systems.

Design and Analysis of a Butler Matrix at 60 GHz Compatible with Metallic-Nanowire-Filled Membrane Fabrication Platform

“…Previous works on millimetre wave devices using MnM technology [13], [14], [15] presented good agreement between measured and simulated results.…”

“…The present work aims to design and analyse a 4 × 4 Butler matrix that can be implemented in metallic-nanowire-filled membrane (MnM) for applications in the 60 GHz band. MnM is a versatile high-frequency, low-cost interposer technology that shows great potential for the development of mm-Wave applications [13], [14]. The Butler matrix will be studied with four-element series patch antenna arrays connected to the output ports, as illustrated in Fig.…”

Design of Interdigital Bandpass Filters for Millimeter Wave Applications

“…Regarding filter implementation, the use of lumped-element at millimeter wave (mmWave) frequencies is extremely difficult because the dimensions of the circuit elements (resistor, inductor, and capacitor) must be much smaller than the wavelength (λ = 5 mm at 60GHz) [2]. Distributed-element circuits approach can produce a similar behavior using λ g /4 resonators, where λ g = λ/ √ ϵ r .…”

“…Recently, an alternative process that uses an alumina substrate with Metallic-Nanowire-Membrane (MnM) demonstrates good results for 3D inductor, cross-overs, hybrids, antennas and other devices at millimeter waves frequencies [2]. This work aims to design and optimize a third-order interdigital band-pass filter with a pass-band from 57 to 66 GHz for manufacturing in MnM Technology.…”
