Miniature Antenna Covers Any Frequency

FRACTAL Antenna Systems, inventor of antennas with fractal geometry, announced the unveiling of a miniaturized drone antenna that enables operators to defeat adversarial drone swarms using drones integrated with its new option known as the FeathR antenna, a patented and patent-pending antenna that combines small size and light weight with wide band coverage and low radar visibility to change the balance in drone warfare.

Currently, the most common way to stop swarms of enemy drones is through the use of high-powered microwaves. This is effective but limitations apply such as the requirement for a vehicle or vessel to support the equipment, and line-of-sight for aiming the microwave beams. The problem is that most drone swarms are flown at low levels through radar-obscuring terrain or in the ground effect sea layer that hinders the opportunities for clear shots.

The new FeathR antenna is used completely differently in that its small size but wideband response enable relatively modest-powered drone-borne jamming transmitters to fly into the midst of the adversarial drone swarm and jam them from inside the swarm itself, regardless of the frequency used by the swarm.

Nathan Cohen, inventor of the fractal antenna and FeathR model, puts it succinctly by saying, “The FeathR antenna puts the wolf in the middle of the hen house.”

The FeathR is the first drone project to come out of FRACTAL’s Owl Works and demonstrated the company’s ability to devise solutions in weeks rather than years. The FeathR is built with stealthy attributes and wideband specs and can take nearly all waveforms and deliver effective jamming of drone swarms.

FRACTAL launched Owl Works earlier this year in February 2025.

Cohen added, “With thirty years of enterprise experience, the right team, and some AI assistance, it’s a whole new ballgame in near real-time solutions, a unique feature of FRACTAL that is not surpassed by the large primes. Cost-effective and fast are now the new rules in electromagnetics.”

The FeathR is able to uplink and downlink from ground-based, space-based, or air-based control systems. For now, the antenna is limited to defense customers and will only be sold to select users.
