In this letter, we present a method to extract the scattering parameters of a microelectronic probe used to feed on-chip or in-package antennas at millimeter-wave frequencies. It is especially important to take into account these losses in the calibration procedure necessary for the extraction of the antenna gain. We are specifically...

An innovative LDS 4G antenna solution operating in the 698-960 MHz band is presented. It is composed of two radiating elements recombined in a single feed broadband antenna system using a diplexer. This circuit is realized thanks to lumped components, assembled directly on the plastic piece which supports the antenna. Corresponding measurements...

In this paper, we present a new wideband miniature branchline coupler as a key circuit to be integrated in 60-GHz packaged beamforming networks for phased-array antennas. First, the integrated passive device (IPD) technology from STMicroelectronics is investigated in the mm-wave range through the simulation, fabrication, and measurements of a...

In this paper, an innovative 4G antenna solution operating in the 698-960 MHz band, is presented. It is composed of two radiating elements recombined in a single feed antenna-system using an integrated power divider/combiner, synthesized thanks to five lumped components. Simulations using realistic SMD (Surface Mount Devices) components allow...

The integration of a Vivaldi antenna on a printed circuit board (PCB) targeting 60-GHz WiGig applications is presented in this letter. The integrated passive device (IPD)technology from STMicroelectronics based on a glass substrate is used for the antenna manufacturing. In free space, the radiation pattern measurements show a realized gain...

The design of a micromachined polyethylene lens for WiGig modules is described and its electromagnetic characteristics are measured. The lens is electromagnetically fed by linearly polarized Tx and Rx patch antennas integrated in an existing ball-grid-array (BGA) organic module. Antennas are separated from each other by a distance of 4.45 mm...

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...
