Directivity of any antenna is directly proportional to square of frequency of transmission.

To make an antenna more directional, it must have a small or narrow beam width. Since beam width is directional to "lambda" or wavelength, that means it is inversely proportional to the frequency. Therefore, increasing its frequency will give it a narrow beam width thus, making the antenna more directional.

Because as you raised the size of antenna there may be an issue of its maintain and it is not possible to tackle such a big antenna.
So therefore, to reduced the size of antenna there is a need to raise its frequency.
So therefore, to reduced the size of antenna there is a need to raise its frequency.
