Multifin Flared Radiator

Antennas are crucial elements in wireless communication technology that decodes and delivers information into the form of electromagnetic waves. Technological innovations that allow antennas to be tuned over a larger bandwidth and offer improved scanning performance are particularly sought after. Current antenna designs have been facing limitations when it comes to delivering an optimal bandwidth and scan performance. These limitations persist despite various innovations in equivalent designs. Hence, a solution that offers individual tuning capability and supports an increased bandwidth is needed to improve performance. 

Technology Description

In this flared antenna, the upper part of the antenna prongs divide into several parallel fins. These parallel fins situated on the energized prong are provided power by a collective electrical feed source, such as a coaxial transmission line that extends into the energization region of the prong. The flared antenna might be a Vivaldi antenna, a stepped notch antenna, or any other flared shape. The unique aspect of this technology lies in the application of separate fins to expand the level of tuning, enriching both BW and scan performance for a given equivalent design. The individual design of each fin pair aids in the optimization of these improvements, allowing them to function independently of each other. This design eliminates dependencies and enhances the performance of the flared antenna.
