Abstract :
Antenna arrays, sectionalized antennas, and antennas which are electrically in the vicinity of 1/2 wavelength in length, can be difficult to design. These types of antennas are good candidates for moment method analysis. A few examples are included to demonstrate the usefulness of moment method techniques in practical situations. Moment method techniques are a powerful and valuable tool for the antenna designer. Personal computers are widely available, as are well documented and tested programs such as NEC and MININEC. The existence of this technology has created the opportunity for more complete design capabilities, as well as easier and more certain adjustment processes for the antenna engineer. These techniques must be used with care, as is the case with all problem-solving that involves complex computer programs, but they have become a major modernizing influence on medium wave antenna engineering
