an infinite planar array of rectangular microstrip patch antenna analysis
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
15 صفحه اولCompact Multiport Array with Reduced Mutual Coupling
A novel design of decoupling network for a compact threeelement array is presented. The proposed decoupling network has simple and compact structure that can be implemented easily with microstrip lines. The conventional microstrip open stubs can be used to match the decoupled ports of the array. The proposed decoupling and matching network is applied to a compact three-monopole array operating ...
متن کاملMutual Coupling Reduction of Microstrip Patch Antenna Array Using Slotted Ground Structure
In microstrip patch antenna array, the mutual coupling is very critical due to surface wave excitation. It leads to degradation in radiation pattern and reduction in gain. In this paper, a method to mitigate mutual coupling effect in an antenna array using Slotted Ground Structure (SGS) at 900MHz and dielectric constant 2.2 is simulated and analyzed using Ansoft HFSS 13. Simulated results show ...
متن کاملCompact Waveguided Metamaterials for Suppression of Mutual Coupling in Microstrip Array
In this paper, suppression of mutual coupling is achieved using compact waveguided metamaterials (WG-MTMs) in between elements of a densely packed microstrip array. Both the E-plane internally folded complementary split ring resonator and the H-plane internally folded complementary split ring resonator are employed to reduce the mutual coupling between adjacent elements. Coupling suppression of...
متن کاملDesign of Planar Microstrip Antenna Arrays and Mutual Coupling Effects
In patch antennas, characteristics such as high gain, beam scanning, or steering capability are possible only when discrete patch elements are combined to form arrays. The elements of an array may be spatially distributed to form a linear, planar, or volume array. Planar arrays have elements distributed on a plane. Planar array configurations are extensively used in both communication and radar...
