Method for compensate cavity effect in aircraft embedded antenna impedance and embedded antenna array for aircraft

A non-protruding aircraft antenna comprising:

• an antenna having an input impedance at an intended operating frequency band;
• an antenna embedment cavity configured for positioning inside an aircraft fuselage, the antenna disposed within the antenna embedment cavity, the antenna embedment cavity being non-resonant and comprising cavity lateral walls and a cavity bottom forming a depression, the walls and bottom configured to accept an active radiating part of the antenna;
• and
• at least one radiofrequency absorber material disposed within the antenna embedment cavity, the radiofrequency absorber material matching the input impedance of the antenna by absorbing electromagnetic waves as a load and eliminating multiple reflections of the electromagnetic waves, wherein the at least one radiofrequency absorber material is disposed on at least a portion of the cavity lateral walls and does not cover the cavity bottom.
