wherein the first frequency band of the integrated antenna is a sub-6G or 4G/3G/2G frequency band and the second frequency band of the integrated antenna is a mmWave frequency band.
2. The integrated antenna according to claim 1 , wherein the first shape is a strip shape or a plate shape.
3. The integrated antenna according to claim 1 , wherein the second shape is a strip shape or a plate shape.
4. The integrated antenna according to claim 1 , wherein the first portion and the second portion are made from metal material.
5. The integrated antenna according to claim 1 , wherein the antenna array is located on a front side or a back side of the second portion.
6. The integrated antenna according to claim 1 , wherein the first antenna includes:
a feed point located on a first side of the second portion; and
a ground point located on a second side of the second portion, opposite to the first side of the second portion.
7. The integrated antenna according to claim 1 , further comprising a processing chip corresponding to the antenna array, the processing chip being disposed on the second portion,
wherein the processing chip processes a signal received by the antenna array or a signal transmitted by the antenna array.
8. The integrated antenna according to claim 7 , further comprising a shielding member, the shielding member being disposed on the second portion for shielding the processing chip.
