Abstract

The utility model discloses a kind of communication antenna radiation enhancement device and omnidirectional communication antenna, it is related to communication equipment technical field, solve the serious signal attenuation of traditional omnidirectional antenna in subway tunnel and other closed environment, there is blind area, the problem that directional antenna cannot satisfy multidirectional communication. Enhancement device includes fixed seat, signal enhancement component and signal reflection component;Fixed seat is detachably connected with omnidirectional antenna body, angle is equipped on it and telescopic adjusting mechanism;Signal enhancement component contains sector radiation enhancer and arc direction sheet, and signal reflection component contains rectangular parabolic reflector. Omnidirectional communication antenna includes vertical polarization dipole antenna body, ground net and pipe clamp buckle. The utility model is through the dual effect of "signal guidance enhancement+redundant signal reflection", effectively reduce the signal attenuation effect in tunnel, reduce signal blind area, and different sections such as tunnel straight section, curve section can be adapted by adjusting mechanism, satisfy multidirectional communication demand in tunnel.
