<p>The antenna, especially for a mobile radio, has a reflector (2) and a radiator (1) with quadratic dipoles (1a,1b) which can be set in a required transmission direction. A dielectric body (3) is over the reflector and/or radiator, positioned to improve at least one transmission characteristic. At least one decoupling element (4) is at the dielectric body on a parallel plane to the reflector or at an angle to it of ~+-20[deg] and preferably ~+-10[deg]. The decoupler has a longitudinal section with a maximum length of 0.4~L and a maximum width of 0.1~L.</p> |
