Abstract:
Using the Geometrical Theory of Diffraction GTD the fields due to a monopole array mounted on an aircraft near the top or bottom were analyzed. The aircraft was modeled in its most basic form an infinitely long elliptical cylinder. The aircraft cross-section at the location of the antenna was modeled as a 2 meter by 4 meter ellipse. The frequency band of operation was 250 mHz to 400 mHz with an average wavelength assumed of 1 meter. The three element array was found to have a beam broadening effect when compared to the array mounted on an infinite ground plane. The array exhibited a poor potential to form a single major lobe in its antenna pattern but had a high mobility of pattern nulls. Author
