Antenna arrangement

An antenna arrangement comprising:

• a first antenna configured to receive and transmit a first set of near field communication (NFC) signals;
• a second antenna configured to receive and transmit a second set of NFC signals wherein the first antenna is coupled in series with the second antenna;
• a first transmitter path extending from a first end to a second end wherein the first antenna is arranged at the second end of the first transmitter path;
• a second transmitter path extending from a first end to a second end wherein the second antenna is arranged at the second end of the second transmitter path;
• a matching circuit comprising a first capacitor arranged in series between the first end of the first transmitter path and the first antenna, a second capacitor arranged in series between the first end of the second transmitter path and the second antenna;
• a first receiver path coupled to the first transmitter path at a first tapping point wherein the first tapping point is between the first end of the first transmitter path and the first antenna;
• and
• a second receiver path coupled to the second transmitter path at a second tapping point wherein the second tapping point is between the first end of the second transmitter path and the second antenna;
• and wherein
• the antenna arrangement is absent an intermediate reference voltage node between the first antenna and the second antenna.

• a matching circuit comprising a first capacitor and a second capacitor, the first capacitor arranged in series between the first end of the first transmitter path and the first antenna, the second capacitor arranged in series between the first end of the second transmitter path and the second antenna;
• a first receiver path coupled to the first transmitter path at a first tapping point between the first end of the first transmitter path and the first antenna;
• and
• a second receiver path coupled to the second transmitter path at a second tapping point between the first end of the second transmitter path and the second antenna;
• and
• wherein the antenna arrangement does not include an intermediate reference voltage node between the first antenna and the second antenna.
