description Embodiments of this application disclose a common aperture antenna and a communication device. The common aperture antenna includes: a reflection panel and a low frequency antenna unit, a frequency selective panel, and a high frequency antenna unit that are disposed on a same side as the reflection panel and that are arranged in sequence. In a direction perpendicular to the reflection panel, a distance between the high frequency antenna unit and the reflection panel is greater than a distance between the low frequency antenna unit and the reflection panel, the frequency selective panel is disposed between the high frequency antenna unit and the low frequency antenna unit, and the frequency selective panel is a reflection ground of the high frequency antenna unit and has a total reflection characteristic for a working frequency of the high frequency antenna unit. In the common aperture antenna in the embodiments of this application, the high frequency antenna unit is designed on a side of the low frequency antenna unit far away from the reflection panel, and the frequency selective panel is disposed between the high frequency antenna unit and the low frequency antenna unit, to miniaturize the antenna and improve radiation performance of each frequency band.
