A circularly polarized (CP) horn antenna is used for transmitting and receiving circularly polarized signals for wireless communication, radar, and imaging applications. But for millimeter wave (mm-wave) and terahertz frequency applications, micro-fabrication techniques are needed which can make them expensive. The design gets expensive and sensitive to fabrication tolerances rendering it not very viable for high frequency applications. To overcome these limitations, FIU inventors have designed a new class of CP horns that are easy to fabricate for high frequencies, are not susceptible to dielectric breakdown, and are better-matched due to their hollow waveguide design.

APPLICATIONS

Mm-wave wireless communication and imaging applications

WPT often uses inductive power delivery, which is the use of non-radiating magnetic fields generated by a transmitter coil to induce a current in a receiver coil. Strongly coupled magnetic resonators systems have shown good efficiency and range, but they require a certain distance between the source and the resonators, and therefore occupy a significant volume.

FIU inventors have designed advantageous systems and methods for WPT that can operate at a lower operating frequency, extended WPT range and higher WPT efficiency.

APPLICATIONS

Can be used in the charging of mobile devices, implantable devices or sensors, embedded sensors for structural health monitoring of concrete structures and bridges, wearable devices and healthcare applications

WPT is a convenient way to power devices. The drawback of current WPT system is that it is only efficient when the transmitter and receiver elements are resonating at the same frequency and are properly aligned. FIU inventors have designed advantageous systems and methods for WPT that are insensitive to misalignment.

APPLICATIONS

Can be used in the wireless charging/powering of mobile devices, implantable devices or sensors, embedded sensors for structural health monitoring of concrete structures and bridges, wearable devices and healthcare applications

Although wireless power transfer (WPT) technology allows wireless power transfer to a receiver, the current WPT technology requires the receiver to be positioned in a specific site, thereby inhibiting the user of the senor from moving. To address this limitation, FIU inventors have designed novel smart clothes that wirelessly transfer power and communicate with a sensor attached on a human body. This technology provides wireless power transfer (WPT) and sensing capabilities at the same time.

APPLICATIONS

• Wearables, health, diagnostics

Satellite communications typically use deployable antennas that can be compressed and expanded. In such applications, it is important for the antenna to be able to fit into a small space and then be able to expand to an operational size once the orbit is reached. FIU researchers have developed origami-folded antennas that are compressible for good stowability and expandable to an operational size while maintaining effective operating properties. These antennas are also tunable; the gain of the antennas can be tuned to specific frequencies by adjusting the amount of expansion of the antennas between a compressed state and an expanded state.

APPLICATIONS

• Airborne and spaceborne antennas
• Tactile, portable and field antennas

The traditional helical antenna only has one sense; either right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP), which is decided by its rolling direction. It is known that the segmented helical antennas (SHAs) can provide approximately equivalent performance compared to the conventional helical antenna. FIU inventors have designed novel and advantageous helical antennas including a RHCP state and a LHCP state that can be switched easily by mechanical rotation around its center axis. 

APPLICATIONS
