Abstract

An enhanced version of aggressive location restoration is presented in this paper. In this proposal, radio resources would be saved based on the cost of wire signal and operation of location databases. A mobile communication system's robustness in case of a location-database failure is improved without the need for periodic location update operations. Meanwhile, a chain of forwarding location pointers has been used during the period of HLR failure. So mobile stations are unconscious of the failure of HLR, and mobile subscribers can always make outgoing calls

Abstract

A small 2.45 GHz radio frequency identification (RFID) tag antenna is presented. The RFID tag antenna is designed as a resonance inductance of the differential power amplifier (PA). The total PA chip area is reduced greatly to only 240 μm x 70 μm due to the fact that a printed circuit board (PCB) dipole antenna substitutes for the two on-chip integrated inductors. The proposed design methodology is verified by comparing the calculations and measurements, which show the tag antenna works at 2.45 GHz. Operating in Class-AB with a 1.8 V supply voltage and 2.45 GHz input signal, the PA shows an output power of 8 dBm at the 1 dB compression point. [ABSTRACT FROM AUTHOR]
