According to the transmission line model, the resonant frequency of the microstrip antenna is shown in Formula 1:f0=c4εre1L+ΔLc is the speed of light in vacuum; because the fringe electric field lines of the antenna exist in the dielectric base layer and the air, the theoretical ...
Microstrip patch antennaThe sillenite-cobaltite nanocomposites with chemical formula (Bi13Co11)Co2O40 鈥 Co3O4 were synthetized and characterized for application as substrate in a microstrip patch antenna. To prepare the sample, the combustion method using urea as fuel was applied. The structural...
First, the patch dimensions and the location of feed point determined by the formulas are examined to design the differentially-driven microstrip antenna. It is found that the width of the patch by the formula should be widened to ensure the excitation of the fundamental mode using probe feeds....
This chapter is focusing on bio‐inspired microstrip antennas, especially on leaf‐ shaped antennas from the Gielis superformula that open a vast research field for more compact antennas with low visual impact. 展开 DOI: 10.5772/INTECHOPEN.69766 年份: 2017 ...
Fig. Microstrip Antenna When the current from the power source reaches the conducting layer through the feed, electromagnetic waves are generated. When the current passes, an electric field is created throughout the patch. The electric field is zero at the center of the patch, maximum (positive...

Using a pattern-based processing approach to capture the behavior of a system instead of using complicated formula is based on the hypothesis that humans interpret information in the form of pattern-like images rather than numerical or logical forms. Confronting any new experiment creates a new ...
