This paper presents a MIMO antenna using two elements in the shape of a ring with a rectangular stub for RFID applications. The proposed MIMO antenna is multiband with center frequencies at 2.45GHz, 3.5GHz, and 5.4GHz. Mutual coupling between the two antenna elements is improved by placing a U-type resonator. The isolation between the antenna elements is more than -15 dB on these three frequency bands. The diversity gain is 10dB, while the ECC is less than 0.05. The antenna is fabricated on a low-cost substrate, FR4, and its dimensions are $31 times 31 times 0.8$ mm3.

Chipless RFID is a potential alternative to chip based RFID for low cost applications. Enhancing the bit capacity and adding the programmable feature in a chipless tag has been approached via multiple techniques. We have taken advantage of the symmetry properties of split ring resonator to construct a mechanically reprogrammable chipless tag. A slotted signal line CPW (SSLCPW) is designed to produce high-Q resonances. Two port simulation results are presented and the tag is able to utilize 1 GHz bandwidth to generate atleast 225 IDs. A practical end to end implementation of the tag with two cross polarized UWB antennas is also proposed and results are presented for selected tag IDs.

As a general introduction to Colossians, readers always face the questions of who wrote the letter, when, who is the intended audience, what is the purpose for writing, what are the themes, how does this writing compare with other writings, and what is the letter's authenticity? As to the latter question of authenticity, its genuineness has been, as Daniel Wallace points out, "assailed on critical grounds" by T. Mayerhoff, F.C. Baur and the Tübingen school (See Wallace below). General consensus seems to suggest Colossians was written by Paul, or should have been since it so closely structures a Paulinian theology, in the end 50's to early 60's during Paul's first Roman imprisonment.The purpose for the letter seems to have been to combat new and popular teaching that would subvert the pure gospel. New Advent says Colossians was written to combat a number of worldly teachings:
