A VERTICAL ARRAY OF TWO LOG PERIODIC DIPOLE ARRAY ANTENNAS,

Abstract

A broadband, horizontally polarized, log periodic dipole array antenna was developed for installation on an airplane. The antenna system consists of a parallel combination of two array antennas with constant electrical spacing and operates over a 1.67 octave frequency band with a voltage standing wave ratio less than 2 to 1 referred to 50 ohms. A radiation pattern gain greater than 9db compared to an isotropic source was obtained. Both development and production data are included in the report. (Author)
