Design of a simple microstrip fed monopole patch antenna for the radio frequency identification (RFID) is presented. The antenna has two different resonant paths (forming an inverted double L-shaped structure), supports two resonances around 2.41 GHz and 5.85 GHz, which are reserved for RFID applications. Effectively consistent radiation pattern and large impedance bandwidth has been observed. Impedance...
Design of a simple microstrip fed monopole patch antenna for the radio frequency identification (RFID) is presented. The antenna has two different resonant paths (forming a C-shaped structure), supports two resonances at around 2.41 GHz and 5.85 GHz, which are reserved for RFID applications. Effectively consistent radiation pattern and large impedance bandwidth has been observed. Impedance bandwidth...
The paper presents simulated and measured results of the UHF RFID antenna realized with dipole matched to a CPS (coplanar stripline) and inductively coupled with small rectangular loop. Such design of the antenna enables easy achieving and controlling high values of the inductive reactance that is necessary for obtaining good matching of antenna to ASIC (Application Specific Integrated Circuit) chip...
A novel 3 b chipless RFID transponder is presented. The transponder comprises three microstrip patch antennas, which are loaded with open circuited (O/C) high impedance stubs. The antennas are resonant at nearby frequencies, and when excited with their respective resonant frequency signals, they re-radiate backscattered signals with distinct phase characteristics. This phase information is encoded...
