millimeter wave antennas

[am.jay.kay]

Hi all,
can anybody suggest me any books or articles that focus on different millimeter wave antennas and their respective applications.
60 GHz is the frequency of interest. I am interested in antenna designs which have been or can be used for applications like gigabit WLANs, HD video streaming, medical side applications etc.?

MM-wave antennas are generally the same types as microwave antennas. The surface precision must be kept to 1/8 f a wavelength which makes them more expensive.
For your project you have to specify the basic parameters for your antenna: beam width, gain, and if you wish to fight interference, also the full radiation pattern. Polarization is also important.

60 GHz band is preferred for indoor and short-range applications due to oxygen attenuation, some 12 dB/km more than free-space loss. You can have a small horn with several mW of power, to transmit your data over some 100 feet indoors. or an outdoor use, a small parabolic dish can be used, with 30-40 dB of gain.

To design a suitable antenna you should start with the full system design including the transmitter power and receiver noise figure, bandwidth,etc. The S/N will indicate what is easier to get for your money, the transmitter power is so far quite expensive (a good output is 0 to +10 dBm). Then the needed antenna gain will show you how much you have to pay forthe pair of antennas. At 60 GHz and indoor application, signal level is usually good but multipath is a problem.
