Antenna product be to be designed for different working frequency range, stock size and volume are all bigger, variant communication
Can system independent design, the degree that be compatible with or be compatible with depend on the bandwidth and cost of antenna system.And the product of exploitation is big
It is mostly complicated, cumbersome, poor universality, high processing costs are designed, and there are certain defects for performance, should not promote, this shifting
Dynamic communication cell covering causes certain difficulty, therefore develops multiband, miniaturization, and simple in structure, flexible design is at low cost
Honest and clean directional aerial is one of current research hotspot.
