Microdispensing of thick-film conductive paste has been demonstrated as a viable approach for manufacturing microwave planar transmission lines. However, the performance and upper frequency range of these lines is limited by the cross-sectional shape and electrical conductivity of the printed paste, as well as the achievable minimum feature size which is typically around $100~\mu \text{m}$ . In this...
A multilayer dielectric rod antenna (DRA) design is proposed for mm-wave applications. The multilayer DRA is formed by a medium permittivity dielectric rod core encased by a low permittivity cladding to increase the peak gain. The antenna is fabricated using fused deposition modeling (FDM) of two thermoplastics; a ceramic composite material for the core and acrylonitrile butadiene styrene (ABS) for...
A 2.4 GHz single-piece additive manufactured tripolar antenna system is presented for integration with a commercially available wireless node. The antenna is 3D-printed using fused deposition modeling of ABS plastic and micro-dispensing of silver paste. Performance is evaluated in anechoic and highly reflective environments achieving a return loss greater than 15 dB at the desired frequency of operation...
A multilayer dielectric rod waveguide (DRW) is designed for operation at an extended Ku-band from 10 to 18 GHz. The proposed design is fully developed and fabricated by using additive manufacturing technologies, particularly fused deposition modeling (FDM). The multilayer DRW is formed by a medium-Λ dielectric core printed with a custom-made ceramic composite and a low permittivity ABS cladding. Both...
A compact, 3D printed tripolar antenna operating at 2.4 GHz is presented. The antenna is designed for integration with a commercial wireless node in order to mitigate multipath and depolarization channel effects that could exist in many machine-to-machine deployments. The antenna substrate is fabricated with fused deposition modeling and the conductive layers by micro-dispensing silver paste. A median...
