Patent ID: 7369095

Claim:
Source-antenna for transmitting/receiving electromagnetic waves comprising on a support an array of n independent radiating elements operating in a first frequency band for receiving or transmitting electromagnetic waves, and an element with longitudinal radiation operating in a second frequency band for transmitting or receiving electromagnetic waves and situated at the center of the array, said longitudinal radiation element having an axis of radiation and each independent radiating element having an own radiating axis, said radiating axis being different for each independent radiating element and different from the axis of radiation of the longitudinal radiation element, the array of n radiating elements and the element with longitudinal radiation having a substantially common phase center, the n radiating elements being arranged symmetrically about the longitudinal-radiation element, wherein each radiating element of the array consists of a traveling wave antenna and the dimensions of the radiating elements of the array being calculated to obtain a radiation pattern equivalent to the radiation pattern of the element with longitudinal radiation.
