Plane antenna system

摘要: PURPOSE:To attain immunity from the effect of rain or snow by inserting a gap holding member made dielectric material with less radio wave loss between plane antenna fitted to an fitting plate and cover covering so as be brought into contact face. CONSTITUTION:An SHF reception 12 forming microstrip is provided mounting 11. A (a) given 11 surface 15 such plastic fitted. Further, shaped 16 inserted inside 15, that is, 12. The foamed plastic. Thus, even when 15,since proper face sticking snow,large deterioration in performance avoided.
