Abstract:

A receiving antenna system, useful from 2.0 to 4.0 gc, was designed. It is a slot fed parabolic antenna which provides a gain of 22 db to vertically polarized signals. A good impedance match to 50 ohms is evidenced by a VSWR less than 2.0 to 1 over an octave bandwidth. The parabolic section is of unique construction in that it reflects vertically polarized signals with virtually 100 efficency while horizontally polarized signals are passed through umimpeded. A capacitive compensating bar is used in the slot to achieve the required impedance match. Author
