In the paper the problem of gain enhancement for radiating elements between two finite plane reflectors, one of which is a partial reflector and the other a perfect conductor, is investigated. The problem is studied numerically using the method of moments and the effect of different parameters is investigated. It is shown that, as is similar to infinite structures, the antenna gain can be increased with finite size reflectors. Furthermore, for finite structures, the gain enhancement can be made larger than that of infinite structures. However, for optimum gain enhancement, the structure parameters must be selected with care
