directivity of horn antenna

Hi Fellows,

I am working on the design of an horn antenna. I have designed a horn antenna operating at 8 GHz frequency. Directivity achieved with this antenna is 18dB. and a beamwidth of 22 degrees. I want to know, is the gain same as the directivity of the antenna. What is the gain I achieve with this antenna?. Can the formula the horn antenna gain is correct :

Gain= 10 * A / wavelength(square)

where, A=width * hieght

One more thing what is your idea about using Quadrifilar antenna at 8GHz frequency. where should I get some material about Quadrifilar Antenna. Waiting for an early reply.
