Researchers at Purdue University have developed a bihelical receiving antenna that efficiently recaptures a portion of signal energy lost due to multipath interference to achieve more powerful received signal. Through an innovative design and the use of directional antennas, this technology is an antenna system that can transmit and receive data over long ranges at low elevations. Furthermore, this technology is low-cost and more
efficient as it requires a lower amount of transmitter power compared to current solutions. This technology can be utilized in rural settings where height restrictions and destructive interference are common issues for current elevated antenna designs. Furthermore, airports, especially rural airports, can utilize this low height antenna to combat the height restrictions and numerous obstacles faced when transmitting important information.

Advantages:

-Reduced-height antennas
-Low-cost solution
-Multi-spectrum
-Efficient

Potential Applications:

-Rural antenna
-Airports
-Rural Wi-Fi
-Areas with obstacles in transmission path
