Atlanta running back Jamal Anderson rushed for 113 yards and two touchdowns, while the Falcons defense intercepted three passes from quarterback Steve Young as they barely escaped with a victory in the first playoff game ever played at the Georgia Dome. This would eventually prove to be the final postseason game in Young's Hall of Fame career, as well as the final game for 49ers defensive end Chris Doleman, who finished his 14-season career with 142.5 sacks.

The antenna offers a 54 MHz bandwidth (890 - 944 MHz) and 8.9 dBi maximum gain.When it comes to the tag and reader antennas for the RFID, designers adopt the concept imitating the radar technology in which the re ader transmits a signal to a tag and the tag sends back its recorded data to the reader.
A typical patch-type RFID antenna has a gain of about 6 dBi and looks like the broad beam pattern above. The designer might like to improve the read range by using an antenna with a higher gain, like the narrow beam antenna above, if angular coverage is not important. By definition, an antenna that has greater than 0 dBi gain does not radiate isotopically (the same in all directions) but has a gain pattern, sometimes referred to as its antenna pattern, or directivity pattern, as illustrated below. in this expert article we discuss rfid reading pattern between different uhf rfid antennas and the user’s impact. Different antennas have different RFID reading patterns, and objects affect the patterns.
Two antennas provide polarization diversity for reading an RFID tag that a single antenna is not able to read due to the tag orientation. This introduced the concept of antenna diversity, which means using more than one antenna to cover a given region in order to overcome the limitations of a single antenna.a self-oscillating switching circuit powered wirelessly, by the antenna signal itself. Once this reader antenna is fed with RF signal of sufficient power, the circuit starts oscillating, switching between the two complex impedance values, and thus changing the antenna radiation pattern. In response to the rising demand for adaptable and versatile RFID reader antenna, this paper presents an integrated reader system featuring an array of four antennas. The primary objective is to design four identical, circularly polarized, high-gain, wide-band antennas that cover the 860–960 MHz UHF RFID band.
We propose a machine learning-based method for RFID indoor localization using a pattern reconfigurable UHF RFID reader antenna array. The received signal strength indicator (RSSI) values (from 10,000 tags) recorded at the reader antenna units are used as features to evaluate the machine learning models with a train-test split of 75%-25%.
