ANTENNA ELEMENT AND ITS MANUFACTURING PROCESS

摘要

FIELD: antenna engineering. ^ SUBSTANCE: hemispherical case of antenna element affording extended band of spiral antenna and its serviceability under impact of vibration loads and at temperatures ranging between -60 and +40 °C has wall thickness reducing from base to top and is manufactured by transfer molding method from epoxy molding material followed by making deepened pattern therein for disposing spiral radiator. Gradual variation of wall thickness from work zone in high-frequency band to that in low-frequency band ensures low VSWR level of broadband spiral antenna. ^ EFFECT: facilitated manufacture, ability of producing identical antenna elements. ^ 3 cl, 2 dwg
