MILLIGAN is Chief Engineer for Milligan \u0026amp; Associates, Inc., a consulting firm that offers wireless communications solutions. He previously was principal engineer at Lockheed Martin Astronautics, where he specialized in microwave antenna design and analysis. Mr. Milligan is the author of the first edition of Modern Antenna Design and coauthor of Antenna Engineering Using Physical Optics.  Learn hands-on antenna design from a leading expert  \u003cp\u003eModern Antenna Design, Second Edition continues the practical approach that marked the popular first edition by distilling theory to the essentials of antenna design without becoming buried in mathematics. Written by an expert antenna designer whose designs have been used on NASA missions to explore Mars and Venus, the book emphasizes and demonstrates real-world applications across a variety of fields, including telecommunications, remote sensing, and broadcasting.\u003c\/p\u003e \u003cp\u003eThe Second Edition reflects developments in antenna design and incorporates the author's hands-on experience teaching antenna courses.
