Description
Summary:In this paper, a new array configuration termed as Spread Orthogonal Loop and Dipole (SOLD) array is presented for estimating direction and polarization parameters of multiple incident signals. In the SOLD array configuration, the spacings of any two adjacent SOLD antennas are set to be mutual primes with respect to a half-wavelength. Moreover, the loop is separated far away from the dipole within a single SOLD antenna. This SOLD array configuration thus imposes a significantly less antenna mutual coupling effect. To demonstrate the practical value of the SOLD array, a joint direction and polarization estimation algorithm is developed subsequently. Simulations are carried out to justify the SOLD array in improving parameter estimation accuracy and in reducing the effect of mutual coupling.
