A company named Drone Shield has developed a 'Drone Gun', which is capable of jamming a drone from up to 1.2 miles (approx. 2 km) away.

I am aware of how the jamming works, where the gun emits frequencies of 2.38Ghz-2.483Ghz and 5.725Ghz-5.825Ghz, which are the most common frequencies a drone operates on. Consequently, this causes the drone to think it is out of range, hence activating its safety system and slowly descending to the ground.
However, I am not entirely sure how the radio wave is focused and directed towards the drone
The following image shows a front on view of the gun, http://imgur.com/a/tB7oM
I've labeled what appears to be the source of the directed radio waves.
Does anybody know what type of directional antenna is in these three labeled pieces of the apparatus? I'm unsure whether they'd be high gain yagi directional antennae or helical antennae.
Also, If anybody is able to offer an explanation of how radio waves are focused and directed into a 'beam' as well as how the distance is increased, this would be much appreciated :)
