Abstract: An antenna and a communications device are disclosed. The antenna includes: multiple feeders, a microstrip antenna array, and at least one energy attenuation circuit; the microstrip antenna array includes multiple array elements, where each of the multiple array elements is connected to a cable feeding port by using one of the multiple feeders; each of the at least one energy attenuation circuit is located at a feeder, where the feeder is one of the multiple feeders and is connected to an array element, and the array element is located at a periphery of the multiple array elements; and the energy attenuation circuit includes a resistor, where the resistor is grounded, and the resistor consumes a part of energy in the feeder when the resistor is grounded.
