Abstract

This paper presents a W-band planar type via-monopole based quasi Yagi-Uda antenna using metal coated through glass silicon via structures. The antenna was designed and fabricated on 350 μm thick borosilicate glass substrate, which has very low dielectric loss compared with silicon at millimeterwave frequencies. We used a microstrip line to feed the antenna, and the Yagi-Uda configuration using via structured radiator; reflectors; and director were fabricated using tungsten coated silicon via structures embedded in reflowed glass substrate with good high frequency characteristics. The proposed antenna achieved vertical polarization in planar configuration with height 0.09λo. High gain with end-fire radiation was achieved due to the Yagi-Uda configuration. Measured results confirmed the fabricated antenna operated in the W-band with 10 dB fractional bandwidth (FBW) of 12.5% from 76.3 to 86.5 GHz and peak gain of 7.82 dBi at 81 GHz in the end-fire direction. Thus, the proposed antenna with end-fire radiation will be useful for millimeter-wave onboard wireless communication, radar imaging, and tracking applications.

Highlights

With the ongoing development of modern communication systems, there has been growing demand for high Gbps data rates [1]; since bandwidth is directly proportional to communication data rates [2]
This paper reports a W-band microstrip line fed viamonopole based quasi Yagi-Uda antenna with vertical polarization and end-fire radiation in planar configuration on a glass substrate
We show that vertical polarization is less prone to path loss, which makes vertical wire antennas suitable candidates to achieve better radiation performance as well as high security
