I am trying to design a coupled line band pass filter on a very high dielectric material (epsilon_r = 70 ). my question, Beside reducing the size of the filter and reducing the radiation loss(due to the high dielectric material), is there is any other advantages of using the high dielectric material?, for example, is the high dielectric materials help in increasing the coupling or allow for other different modes to propagate and increase the filtering?.
