Three Dimensional Antenna Array System with Troughs
A system and method for installing and deploying antenna elements on antenna arrays cards is disclosed. The antenna elements are installed on front sides of the antenna array cards and active components are installed on back sides of the antenna array cards. The antenna array cards are then installed within enclosures to create troughs with the antenna elements. Alternatively, magnetic and electric antenna elements are installed together on the front sides of the antenna array cards to create non-homogenous arrays.
