Patent attributes
An antenna assembly for use in a tile architecture antenna system. The antenna assembly comprises: i) a first substrate layer having a first surface; ii) a first antenna disposed in an X-Y plane on the first surface of the first substrate layer; iii) a second substrate layer having a first surface, the second substrate layer displaced in the Z-direction with respect to the X-Y plane on the first surface of the first substrate layer; and iv) a first tuning balun disposed on the first surface of the second substrate layer and coupled to the first antenna by means of a first feed via. The antenna assembly further comprises a first transmission line disposed on the first surface of the second substrate layer. The first transmission line is coupled to the first antenna by means of a second feed via.
