THE TRANSISTORIZED DIPOLE ANTENNAFIER
Abstract
The transistorized dipole antennafier is a novel integrated design uniting a resonant half-wave dipole antenna with a VHF transistor amplifier, and providing a simple, stable, compact, high gain, low-noise, and inexpensive element suitable for use alone or in arrays. The design philosophy is to match the resonant dipole directly into the transistor amplifier, eliminating the usual transmission lines and auxiliary tuned circuits. The result is a miximum bandwidth device, with higher gain and better noise performance than is possible in conventional operation using the same components separately. Measurements have been made at 146 mc on a transistorized dipole antennafier, with results of 12. 5 db gain, less than 400 K effective noise temperature, bandwidth approximately equal to that of the dipole antenna itself, and no effect whatever on the radiation pattern of the dipole.
