In this paper, we have proposed a novel passive ultra high frequency (UHF) radio frequency identification (RFID) metal tag antenna mountable on the metallic surface to resonate at 930 MHz. The techniques with double slits for impedance matching and reading distance enhancement is used to obtain a good performance. All simulations are carried out by Ansoft HFSS software and Intermec read verifies the...
Bandwidth, size and polarization optimizations of a single layer wide‐band full and half E‐shaped patch antenna fed through a coaxial probe are described. The finite‐difference time‐domain (FDTD) method was used in the simulations. Measurements and simulations using capacitive feeding and shorting pins are presented. Using these techniques, the bandwidth can be improved up to 32% and the antenna area...
The authors report the use of genetic algorithm (GA) to design ground shapes for planar inverted F antennas (PIFA) for broadband applications. Full-wave electromagnetic commercial software is employed to predict the performance of microstrip antennas with arbitrary ground shapes. GA with two-point crossover is implemented. Two novel optimized antennas are presented. Optimized antennas reach 14% and...
