Abstract: Provided is an aerial-staying type communication relay apparatus that can suppress fluctuations in a directivity pattern due to reflection at an antenna-mounting member to which a service link antenna is mounted, stably fix a footprint of a cell, and as a result, prevent deterioration of communication quality. The communication relay apparatus includes an antenna having plural antenna elements that form a cell for performing a radio communication of a service link to and from the terminal apparatus and an antenna-mounting member to which the antenna is mounted, and a layer of radio wave absorber or a layer of frequency-selective electromagnetic shielding member that selectively shields radio waves having a frequency of the service link, which is provided on an outer surface exposed to an outside of the antenna-mounting member. Phases and amplitudes of signals transmitted and received via each of the plural antenna elements of the antenna may be controlled.
