Abstract: We present a new explicit family of polynomials orthogonal on the unit circle with a dense point spectrum. This family is expressed in terms of $q$-hypergeometric function of type ${_2}\phi_1$. The orthogonality measure is the wrapped geometric distribution. Some “classical” properties of the above polynomials are presented.

Keywords: polynomials orthogonal on the unit circle, wrapped geometric dustribution, dense point spectrum.
