Mutual 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 کاملMutual Coupling Reduction Using Dumbbell Defected Ground Structure for Multiband Microstrip Antenna Array
A novel design of multiband microstrip antenna array with dumbbell shape defected ground structure (DGS) is presented. The DGS is inserted into the ground plane between the two elements of the antenna array in order to suppress mutual coupling. Both simulation and measurement results verified that the DGS improved the radiation properties of the antenna array. Measurement results of the DGS ant...
متن کاملan 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...

Microstrip antennas are widely used in a broad range of military and commercial applications due to its low cost, low profile, easy fabrication and light weight. But this kind of antenna also has some drawbacks. For example, the diffraction of surface waves at the edge of finite grounded substrate decreases the antenna efficiency and degrades the antenna pattern [1]. In the phased array antenna...
متن کاملMeandered UC-EBG structure for a reduction of the mutual coupling in a patch antenna array
A meandered uniplanar compact electromagnetic bandgap structure is proposed. Meandered microstrip lines between adjacent cells are used to increase the equivalent inductance. As a result, the dimension of the proposed EBG structure is more compact and its frequency band-gap is wider than that of the conventional uniplanar EBG structure. Two patch arrays with and without an EBG structure were de...
