Antenna structure for a radio frequency identification (rfid) reader, method of manufacturing thereof, rfid reader and rfid system

A method of manufacturing an antenna structure for a radio frequency identification (RFID) reader, the method comprising:

• providing a substrate;
• forming an antenna on the substrate, the antenna comprising:
• a peripheral frame portion;
• a first strip section disposed at a first side of the peripheral frame portion;
• and
• a second strip section disposed at a second side of the peripheral frame portion,
• wherein the first strip section and the second strip section each comprises a plurality of spaced-apart strip portions extending from a first part of the peripheral frame portion to a second part of the peripheral frame portion.
