Abstract
A miniaturized antenna providing multiband functionality includes a ground portion, a feeder, a first radiator, and a second radiator. The ground portion is grounded. The feeder has a feed end. The feed end can transmit and receive radio frequency (RF) signals. The first radiator is connected to the ground portion. The first radiator and the feeder are spaced apart from each other by a gap. The gap can cause a coupling between the first radiator and the feeder to transmit the RF signal. The second radiator is connected to the first radiator. The second radiator can transmit the RF signal from the first radiator. Multi-band operation is obtained and size of antenna is reduced.
