Increasingly stringent design constraints imposed by compact wireless devices for telecommunications, defense, and aerospace systems require the miniaturization of antennas. Unlike most electronic components, which benefi t from decreased size, antennas suffer limitations in gain, effi ciency, system range, and bandwidth when their size is reduced below a(More)
This paper reviews the key technological advances and regulatory decisions over the past century that have helped to enhance the use of the radio spectrum, and Blessons learned,[ and concludes by offering a bold vision of future spectrum access technologies.
