Advanced Antenna Architectures

Contact: Andrea Neto

The Tera-Hertz portion of the spectrum presents unique potentials for advanced applications. Currently the THz spectrum is revealing the mechanisms at the origin of our universe and provides the means to monitor the health of our planet via satellite based sensing of critical gases.

Potentially time domain sensing of the THz spectrum will be the ideal tool for a vast variety of medical and security applications.

Presently, systems in the THz regime are extremely expensive and consequently the THz spectrum is still the domain of only niche (expensive) scientific applications. The main problems are the lack of power and sensitivity. The wide unused THz spectral bandwidth is, herself, the only widely available resource that in the future can compensate for these problems. But, so far, when scientists try to really use the bandwidth, they run into an insurmountable physical limit: antenna dispersion. Antenna dispersion modifies the signal‟s spectrum in a wavelength dependent manner in all types of radiation, but is particularly deleterious to THz signals because the spectrum is too wide and with foreseeable technology it cannot be digitized.

The goal of this proposal is to introduce break-through antenna technology that will eliminate the dispersion bottle neck and revolutionize Time Domain sensing and Spectroscopic Space Science. Achieving these goals the project will pole vault THz imaging technology into the 21-th century and develop critically important enabling technologies which will satisfy the electrical engineering needs of the next 30 years and in the long run will enable multi Tera-bit wireless communications.


3D Elements For Phased Array Systems

The goal is to develop 3D antenna elements for phased arrays with integrated filtering solutions and suitable pattern shaping.

Efficient on-chip antennas for terahertz applications

Silicon technology promises affordable integrated THz systems, but at the cost of limited achievable efficiency. Antenna solutions to overcome this bottleneck efficiency will be investigated.

THz silicon-integrated camera for low-cost imaging applications

Develop a real-time multi pixel passive radiometer, operating between 0.1 THz and 1THz, integrated in a silicon based technology, with temperature resolution better than 1K
