“…e performance of the antenna greatly depends upon the substrate parameters such as uniformity, dielectric constant, and loss tangent [1]. Extensive literature surveys were performed regarding the parameters stating that certain substrates produce an improvement in bandwidth performance [2][3][4][5][6][7][8]. Another survey reported that the material contains less values of loss tangent and dielectric constants and produces better result compared to higher values [9].…”

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.

Antenna is all important part of GPS receivers，there is a great need for the design and production of new antennas which are fully compatible with modernized signals. Because of their advantages such as low cost, compact size, low profile，ability to support dual-frequency and circular polarization operation, microstrip patch antennas have become widely used in GPS antenna designs. A circular polarization patch antennas are proposed in the paper. The antenna designed to operate at L1(1575.42MHz) and L5(1176.45MHz)frequency bands. Initially, a comer-truncated patch antenna for GPS L1 operation was designed to validate simulation in Ansoft High Frequency Structure Simulator(HFSS), the results obtained for this antenna were used to design the two proposed antennas,and designed antennas are presented．
