why is dual band antenna at 28/38 ghz more important than tow single band antennas
If it is correctly designed it is smaller so costs less to make and means that the equipment it is part of can be smaller and lighter.
Shivani,
It can save money and space. Dual band antenna can be realized with the dimensions of single band antenna only. It may take little higher dimensions. Moreover, if the two bands are not used at a time in any case then dual band antenna is far better than single band antenna.
Can anyone help with this comsol error: was an undefined value found in the Solvermodel?
The dual band antenna can be designed to occupy less than half the space needed for two single antennas. Thus cost and space can be reduced when using dual band antennas.

In some cases of antenna design, space management is very important in addition to cost cutting. Dual band antennas can be fabricated with much less footprint area compared to two different antennas at required frequencies if properly designed. In some cases, device might need to transmit/receive over any of two bands time to time but not simultaneously; then, a dual band antenna plays an important role.

Though we have other lossy materials such as nelco why do we use pla for 3d printin.?
For miniaturization, reliability and cost effectiveness dual band antennas are preferred.
