Mutual 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 in Longitudinal Arrays of Compound Slots
The arrays of compound-slots (inclined and displaced from waveguide centre) are not so common in the literature and the existing systematic method of design does not take into account the presence of surrounding elements. For this kind of slots, the reasons why the Elliott’s procedure cannot be applied are physically explained. A new method based on circuit theory and scattering matrices connec...
متن کاملTachkling mutual coupling in antenna arrays for wireless communications
A new model for tacking mutual coupling in wireless communications is introduced. A new concept of receiving mutual impedance is introduced and explained theoretically. Receiving mutual impedances for typical antenna arrays are obtained. Application of the new method is demonstrated in several arrays for direction finding, adaptive nulling, and MIMO communications.
متن کاملNull Steering GPS Array in the Presence of Mutual Coupling
A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...
متن کاملPhase-locked laser arrays through global antenna mutual coupling
Phase locking of an array of lasers is a highly effective method in beam shaping because it increases the output power and reduces the lasing threshold. Here, we show a conceptually novel phase-locking mechanism based on ‘antenna mutual coupling’ in which laser elements interact through far-field radiations with definite phase relations. This allows a longrange global coupling among the array e...
