A new UWB tightly coupled antenna array is presented. In traditional antenna design, the distance between array elements is considered carefully to reduce mutual coupling effect, however coupling is not only desired but also enhanced and adjusted to increase array bandwidth in this new array. The equivalent circuit model of dipole array above a ground plane is discussed and its input impedance is...
Uniform circular array (UCA) based on coupled oscillators is introduced for new phased array. A phase model of the array is proposed and a set of nonlinear phase differential equations are studied. Linear phase distribution among UCA is achieved using York's method for coupled oscillators array, causing error in beam scaning of coupled oscillators UCA, and the inter-element phase shift that can be...
