The improvement of the capabilities of wireless communication devices (smartphone, tablets …) which require higher and higher data rate, leads to a significant increase of the data traffic needed by each end user. This strong consumer demand for higher data-rate and coverage is stressing a lot the capacity of existing cellular networks. In...

This letter reports a microstrip mesh array antenna in a low temperature co-fired ceramic (LTCC) technology for 94-GHz applications. The microstrip mesh array antenna enlarges the system polarization diversity with the capability of being utilized to support the simultaneous reception in two orthogonal polarizations, as well as transmission in...

A designed microstrip grid array antenna at 94 GHz in a low-temperature co-fired ceramic (LTCC) technology was fabricated and measured. The designed and measured results are in good agreement. They show a 10-dB impedance bandwidth of 5.12 GHz from 90 GHz to 95.12 GHz (or 5.45% at 94 GHz), a maximal peak realized of 17.1 dBi with a 3-dB gain...

In this letter, the design and measurement results of a millimeter-wave beam switching antenna are presented.

This paper investigates the performance of a 3D-printed plastic lens operating in the 120 GHz frequency band. An Integrated Passive Device module with built-in linearly polarized patch antenna is used as the source of the lens. The profile of the lens is based on elliptical shape. It is first optimized with Geometrical Optics and Physical...

During the past years, various research teams developed 60 GHz chipset solutions, using both advanced CMOS [1] and BiCMOS [2] technologies. But for the 60 GHz market to flourish not only low cost RFICs are required, low cost antennas and packages are also key elements. Recently, low cost High Density Interconnect (HDI) organic technology has...
