Design of High Impedance Electromagnetic Surfaces for Mutual Coupling Reduction in Patch Antenna Array
A compact planar meander-bridge high impedance electromagnetic structure (MBHIES) was designed and its bandgap characteristics, mutual coupling reduction abilities were studied and compared in detail. Several parametric analyses were performed to obtain optimized design values and the transmission responses were calculated through the suspended microstrip line and waveguide simulation methods. ...
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...
متن کاملMutual Coupling Reduction in Patch Antenna Arrays Using Corrugated Structure
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 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 کاملOptimum High Impedance Surface Configu- Ration for Mutual Coupling Reduction in Small Antenna Arrays
In this paper, the electromagnetic properties of two different High Impedance Surfaces (HIS) with or without Electromagnetic Band Gap (EBG) in different configurations are investigated for mutual coupling reduction in small antenna arrays. The resonant mechanisms of these structures are studied using transmission calculations in a parallel plate waveguide. An optimum configuration is then propo...
