A class of low gain broadband antennas

The experimental characteristics of a class of small, low and medium gain, broadband antennas are discussed. Theoretical analysis and comparison with more common antenna structures are also presented. Three basic antenna types are described. Patterns and VSWR characteristics of each type are shown. Combinations of these basic types were investigated. Included were structures having such characteristics as medium gain, uniform patterns, and balanced feeding over a wide frequency range. The important features of these antennas include small physical size and inherent broadband.
