Vertically oriented beams using antenna arrays
Yes, this can be done by adjusting the phase of the signal fed into each element of the array A, so that constructive interference is achieved in the direction you want to transmit, and destructive interference is produced in other directions. 

This is called a phased antenna array.

The details of how well the signal can be directed, how much energy leaks into other directions, etc., depends on the size of the array, the number of elements, etc.
