But if the application also needs multiple directions, then an antenna with a lower maximum gain and multidirectional radiation pattern is needed.
KEF wanted to extend the Uni-Q's frequency response, obviating the need for a second super-tweeter, and also in reducing edge texture distortions, smoothing the amplitude response, and improving the already excellent radiation patterns.
It also excites several modes that may disturb the radiation pattern symmetry.
A method that has been developed to determine the phase and amplitude of the excitation needed at each antenna element to produce a desired radiation pattern.
Fortunately, absolute aiming precision would not be required, meaning that even a longish listening couch would be entirely within the desired radiation pattern area.
Phased signals were used for beamforming, eliminating the drawback of requiring a change in mechanical parts to reorient the radiation pattern.

The radiation pattern for E plane and H-plane of the proposed antenna at cut off frequency depicts in fig 4 (a) and (b).
The EL/M-2052 uses an array of solid-state transmit/receive modules designed to dynamically shape the radiation pattern using an ultra-low side-lobe antenna.
It could not be enlarged without introducing significant narrowing of the XdS horizontal radiation pattern above lkHz.
When the [CMB] data gets better, we'll see either [the radiation pattern predicted by] the standard model or we'll see a signature for something new, like this time-varying alpha," Spergel says.
The HCR antenna platform provides frequency agility, low visibility, wide bandwidth and a low angle radiation pattern which is superior to traditional gain antennas in most applications.
