Additively Manufactured Horn Antennas

Additive manufacturing methods have proven to offer many advantages in manufacturing a wide range of products. These methods have advantages of rapid prototyping, rapid production, and the ability to produce mechanical parts that cannot be realized with subtractive methods. Recent work toward the development of horn antennas produced using additive methods has been accomplished. The methods have been shown to produce horn antennas capable of meeting a variety of applications where accuracy and repeatability are key metrics. A comparison of methods is presented along with advantages and disadvantages.
