Abstract: An antenna includes a first antenna having a first feeding portion and at least one stub, and a second antenna having a second feeding portion and at least one stub. The first feeding portion is disposed on a first side of a first diagonal line of the rectangular region. The at least one stub of the first antenna extends from the first feeding portion in a first direction. A first angle is between the first direction and a long-edge direction of the rectangular region. The second feeding portion is disposed on a second side of the first diagonal line of the rectangular region. The at least one stub of the second antenna extends from the second feeding portion in a second direction. A second angle is between the second direction and the long-edge direction of the rectangular region and is different from the first angle.

Abstract: A synchronous rectifier control circuit an includes a current transformer (CT), a bridge rectifier, and a comparator, where the CT is connected in series to a secondary side, performs sampling on a loop current of the secondary side to obtain a current detection signal, and outputs the obtained current detection signal to the bridge rectifier; the bridge rectifier acquires a secondary-side sampling current according to the current detection signal, and outputs the secondary-side sampling current to the comparator so that the comparator generates a voltage difference; and an output signal of the comparator turns over so as to control on and off of a synchronous rectifier transistor. In this way, high-speed and high-precision control over a synchronous rectifier transistor can be implemented. The control is simple and is low in cost.
