Antenna and communications apparatus

A communications apparatus comprising:

• a transceiver comprising a receiver and a transmitter;
• and
• an antenna coupled to the receiver and the transmitter, wherein the antenna comprises:
• a plurality of surface radiating patches;
• a plurality of inner radiating patches;
• a plurality of antenna feeders coupled to the inner radiating patches;
• an organic resin substrate comprising a first dielectric constant or a first dielectric loss, and a first coefficient of thermal expansion;
• a first dielectric substrate disposed between the surface radiating patches and the inner radiating patches, wherein a second dielectric constant or a second dielectric loss of the first dielectric substrate is lower than the second dielectric constant or the second dielectric loss;
• and
• a second dielectric substrate disposed below the inner radiating patches and configured to carry a first part of the antenna feeders, wherein a second coefficient of thermal expansion of the second dielectric substrate is lower than the first coefficient of thermal expansion.
