| Summary: | In the retransmission based chipless RFID, the receiving and transmitting antennas are an essential element and play a vital role for the tag performance and occupied area as well. In this article a new planar microstrip keyhole shape UWB antenna for retransmission based chipless RFID tag is proposed. The proposed antenna is a UWB antenna, covering from 3.45 GHz to 10.7 GHz and has a 7.25 GHz bandwidth with a dimension of only 32×20 mm2. The antenna has the radiation efficiency between 96.5% to 99% within the bandwidth. The radiation pattern of the antenna is Omnidirectional and the max realized gain is 4 dBi which is suitable for the transmitting and receiving antennas for chipless retransmission based RFID tags and readers as well |
