Low-profile and extremely compact SATCOM antenna (230-350 MHz band). A low-loss matching circuit allows constant load on the output of the radio device with VSWR less than 2:1 over all the operative band. The circuit protects also the radio device against the reflected power thanks a power dissipator. The EVO-A-SAT Compact omnidirectional azimuthal radiation pattern makes the SAT link independent by the heading of the carrier on which the antenna is installed. EVO-A-SAT Compact has been designed without integrated ground plane reflectors reducing its overall size, as the same contribution of the reflectors to the antenna efficiency is obtained by the vehicle roof according to a custom tuning.
