Abstract :
In this paper, the effects of semi-spherical radome and nose radome enclosed on the characteristics of antenna are investigated in detail by the means of aperture-integration and surface-integration (AI-SI). The AI-SI method is superior to ray tracing when the radome curvature varies significantly. Besides, this algorithm is simply and can be appropriate for any aperture. Calculated far-field patterns enclosed semi-spherical using this numerically technique agree well with the exact pattern for an aperture antenna radiating. In the presence of nose radome with εr=5.2-0.08j, the energy transmission is 73.7%.
