  • 1. IEEE-Paper Cracking:“Antenna Technologies: Past,Present, and Future”978-1-4673-0037-7, Constantine A. Balanis, published 2012Mohammad Arif HarfiantoIEEE - Antenna and Propagation Society MemberIEEE Student Branch of Institut Teknologi Telkom MemberHead of Research Divisions – Laboratorium Antena Institut Teknologi Telkom
  • 2. Abstract “The evolution of antenna technology is reviewed, from the days of Marconi to the present. Various periods over which antenna technology has been revitalized are reviewed, and the various antenna configurations developed during those periods are summarized along with so me of their respective key characteristics. The history starts at the beginning of the 20th century and the respective technologies developed in the decades that follow are identified. Individuals that played a key role, especially dur ing the early stages of antenna technology, are identified. Future trends and needs are speculated. Key technologies that will contribute to future advancements are identified and will be presented at the conference.” Historical Story Future Advancement of Antenna Technology2 07/23/12
