The advantages can be considered in perspective of propagation, bandwidth, and gains.
v-band maybe more! because it involves 60GHz frequency. this is a license free band.
Depends on your application . If point to point very short distance high speed data transfer is your need, then 60 GHz band is the best option.
57-66/64 GHZ band is Unlicensed world wide...hence suggestible for wireless applications
you can consider the free space absorption (specially oxygen ) diagram in 60 GHZ.
there is a peak in this frequency. 60 GHZ is the best candidate for indoor private applications.
If your purpose of design is for short distances, then V-Band is the best Option. Because, if it is used for Long range communication, there will be Absorption of wave energy from Oxygen and Water vapour in the atmosphere. As it is also unlicensed, there is an Advantage.
60 GHz is in V Band. This frequency spectrum is unlicensed in all the countries. Around 7 GHz bandwidth is available in this spectrum. In this spectrum attenuation is more, specifically rain attenuation. so this band can be preferred for short distance indoor communication. phase array antenna can be consider for V band communication.
This band of frequency is suggested for high data transmission. You can try the design of antenna. In future surely we are going to use this band.
You have to study the propagation characteristics of 60 GHz. Then decide your antenna design parameter. For the parameter, design the antenna. You can use simulation tool at the beginning.
Two perspectives are in favor of frequencies around 60 GHz i.e. it is an unlicensed band and environmental sensitivity especially oxygen absorption makes it ideal for short range communication. Personal area network, body area network, collision avoidance radar are the potential applications for such a antenna design besides many other.
Also the bandwidth availability is obviously more in this band when compared with the other one.
Another advantage being the size of antenna directly influencing the gain aspects. With higher frequencies, you could go for antenna arrays meeting your design aspects.
Millimeter wave band is from 30GHz to 300GHz. Therefore depending on application, studying absorption nature of wave at millimeter wave band, some band is used. Because of various advantages, 60GHz V-band is used (like, intelligent transport system) for many applications and antenna design at millimeter wave uses 60GHz band
