“…e importance of the FR 4 substrate is it can maintain the most important property of electrical insulation and mechanical specification in both wet or dry conditions. In the proposed RFID reader antenna, FR 4 is used as a substrate as it exhibits better performance [17][18][19][20][21][22][23].…”

The proposed RFID reader antenna progressed with perfect electric conductor (PEC) as the radiating element and FR 4 as the substrate to achieve circular polarization, enhancement in bandwidth, and read range. The design presents a CPW feed RFID antenna for near-field reading applications, between the range of 903 MHz to 929 MHz. The operating frequency of the proposed design is 900 MHz, axial ratio of the model is less than 3 dB, impedance bandwidth is 256 MHz, and axial bandwidth is 36 MHz, proving to be adequate for near-field RFID reader applications such as item-level tagging and smart shelf. The proposed antenna model is realized with fractal structure to achieve miniaturization. The developed antenna is optimized using EM software for numerical analysis. The designed antenna is fabricated, and the prototype is characterized in terms of dielectric constant and loss tangent. The obtained results indicate high correlation with simulation results.

“…The antennas are one of the main components in these communicating systems and their tunability allows for a reduced size in a multiple standards system. They can be tuned in terms of frequency [1][2][3][4][5][6][7][8][9] in order to work in several frequency bands of radiation patterns [10,11] in order to modify the orientation of the beam and the polarization [12][13][14][15][16][17][18][19][20][21]. Among the various topologies of antennas, microstrip patch antennas are very common antennas used for their compactness, ease of manufacture and low cost.…”

On-Chip Polarization Reconfigurable Microstrip Patch Antennas Using Semiconductor Distributed Doped Areas (ScDDAs)

This paper presents two polarization reconfigurable patch antennas using semiconductor distributed doped areas (ScDDAs) as active components. One proposed antenna has a switching polarization between two linear ones, while the other one has a polarization able to commute from a linear to a circular one. The antennas are designed on a silicon substrate in order to have the ScDDAs integrated in the substrate, overcoming the needs of classical PIN diodes. Therefore, the proposed co-design method between the antenna and the ScDDAs permits us to optimize the global reconfigurable function, designing both parts in the same process flow. Both demonstrators have a resonant frequency of around 5 GHz. The simulated results fit well with the measured ones.
