6-15 GHz wide scanning connected array

In this work we report on the design, manufacturing and testing of a dual-polarized array of connected slots radiating in the presence of an artificial dielectric superstrate. The prototype array consists of 512 elements, i.e. 16×16 connected slots for each of the two polarizations. The antenna array is realized with a single multi-layer printed...

Optical Performance of a Wideband 28nm CMOS Double Bow-Tie Slot Antenna for Imaging Applications

The optical performance of a wideband double bowtie slot antenna, implemented in 28nm CMOS technology, is evaluated. The antenna serves as a verification antenna for an uncooled single-pixel radiometer operating from 200 GHz to 600 GHz. The performance is evaluated in terms of radiometric pattern that is derived from the measured radiation...

Connected-Slot Array with Artificial Dielectrics: A 6 to 15 GHz Dual-Pol Wide-Scan Prototype

In this work we report on the design, manufacturing and testing of a dual-polarized array of connected slots radiating in the presence of an artificial dielectric superstrate. The prototype array consists of 512 elements, i.e. 16×16 connected slots for each of the two polarizations. The antenna array is realized with a single multi...

A Wideband Leaky Lens Antenna with Frequency-Stable Beams for DESHIMA Spectrometer

DESHIMA (Deep Spectroscopic High-redshift Mapper) is an instrument aiming at efficiently making spectroscopic redshift measurements of sub-mm wave galaxies (SMGs), thereby providing about the formation and the evolution of stars and galaxies. The aim of this work is to provide a preliminary study into the design of a wideband leaky lens antenna...

Efficiency and Bandwidth Enhancement of On-Chip Antennas by Using Connected Arrays and Artificial Dielectrics

On-chip antennas operating in the THz frequency range are characterized by narrow bandwidth and poor radiation efficiency. This is because they are electrically very close to the ground plane that is used to shield the antenna from the lossy substrate. In this work we propose a novel approach to increase the efficiency and the bandwidth of...

A Planar Wideband Wide-Scan Phased Array: Connected Array Loaded with Artificial Dielectric Layers

We present a novel concept for wideband, wide-scan phased array applications. The array is composed by connected-slot elements loaded with artificial dielectric superstrates. The proposed solution consists of a single multi-layer planar printed circuit board (PCB) and does not require the typically employed vertical arrangement of multiple PCBs....
