Beam width of slot antenna

That higher gain antennas have narrower beam-widths is a function of physical laws.These antennas are usually dipole antennas mounted in a housing that allows remote placement, but are otherwise no different than stock dipoles that ship with receivers.

The Sinuous Antenna

The S11 and radiation of the slot array antenna unit are shown in Figure 3. The −10 dB impedance bandwidth is from 13.4 to 15.2 GHz (relative bandwidth is 12%), with a gain of 7.86 dB at 14 GHz. The beam width is 140° in the E-plane, which indicates that it can be used as a unit antenna for a wide-angle coverage phased array. Directional antenna - Wikipedia
