摘要： A built-in antenna of a portable wireless terminal is provided. The antenna includes a first antenna radiator, a carrier, and at least one second antenna radiator. The first antenna radiator transmits/receives a signal. The first antenna radiator is attached to a carrier. The at least one second antenna radiator is detachable from the carrier and is electrically connected with the first antenna radiator when coupled to the carrier to update a resonance frequency in cooperation with the first antenna radiator.

摘要： An active magnetic antenna with a ferrite core having a winding is provided, forming a frame magnetic antenna which is connected with a low-noise transistor, to amplify a signal of the frame magnetic antenna. A base of the transistor is connected directly to one contact of the winding, and a second contact of the winding is capable of shifting a voltage of the base of the transistor. The impedance of the frame magnetic antenna is adjusted as a complex conjugate with an impedance of the base of the transistor of the low-noise amplifier, and the winding eliminates its own resonances.
