Abstract: This paper analyzes the influence of radome on the antenna radiation performance and antenna installation the requirement of mechanical strength, considers the structural design, material selection and molding process and so on synthetically, designs a new structure form and the molding process, and realizes the antenna radiant surface low dielectric/low loss, low density and the non-radiant surface of high mechanical strength. Through simulation and comparative analysis, the design can increase the average gain of 3.5 G frequency band antenna by 0.2~0.3 dB, solve various problems existing in the current radome technology, truly and comprehensively realize the low dielectric/low loss, lightweight, better surface quality, more green and environmental protection, is the ideal choice of 5G era antenna.
Keywords: low dielectric; low loss; light; environmental protection; radiant surface; non-radiant surface; composite extrusion; radome
