The utility model discloses an artificial dielectric cylindrical lens 5 beam antenna contains the super wide band artificial dielectric lens of an appearance for the cylinder to and install 5 the sameindependent antenna element on lens, dipole or the microstrip oscillator of every antenna element for having the metal ground board. The beam gain of antenna is the beam gain for 18dBi, nominal gain.Is they antenna element frequency 1710 2690MHz, gain >, 8dBi, zhu bobi <, 1.4, ge lidu >, 28dB, third order intermodulation <, 150dBc. This antenna forms 5 beam, the horizontal plane beam issharp shape beam, and the perpendicular beam is for composing the fan -shaped broad beam of shape, and the width is three times of traditional 5 beam antenna. The utility model provides an artificialdielectric cylindrical lens 5 beam antenna is a 5 beam antenna who covers 120 sectors, and perpendicular beam width is three times of the same gain base station antenna, need not to set up the angleof declination electricity and transfers the mechanism, and the signal interference ratio is higher simultaneously.
