Need some guide lines regarding designing an antenna for Millimeter wave applications

I have chosen my application for which i am going to design an antenna,but i need some guidelines so that which type of antenna i should go on with to meet my application and how to start it with?
Also i would be very much helpful if anybody attach a paper or a link that could help me to move with my design regarding millimeter wave application ie, 30Ghz to 300Ghz
thank you in advance

MM-wave antennas are designed like any microwave antennas, you only scale down their dimensions as the wavelength changes. Find many good design books since WW II. Try google.

First to design any antenna you must know the specifications from the system parameters.

choose the type of the antenna based on your application. if you want communicate in one particular direction, choose directional antennas. if otherwise, omni directional antenna. im not really familiar with millimeter wave antennas. link below may help you.
