Apparatus, in particular measuring device having an antenna, for acquiring a consumption quantity

An apparatus or measuring device for acquiring a consumption quantity, the apparatus comprising:

• a housing having an interior with a maximum diameter;
• a circuit board disposed inside said housing;
• an antenna disposed at or on said circuit board;
• a communication device adapted to transmit data at a given carrier frequency between the apparatus and an external device via said antenna;
• a dielectric disposed inside said housing, said dielectric having a permittivity influencing a range or efficiency of said antenna relative to the given carrier frequency;
• and
• at least one of:
• said circuit board or a metallic or metal-containing shielding device being disposed between said dielectric and said antenna, or
• a minimum distance being provided from said antenna to said dielectric, said minimum distance being at least 30% of said maximum diameter.
