The filter comprises plural resonators, a first of the plural resonators is operatively connected to a first feed point and a second of the plural resonators is operatively connected to a second feed point. A third of the plural resonators is a half wavelength resonator and may be operatively connected to the first, second and/or other plural resonators. The third resonator may also comprise a plurality of resonators whereby the position and number of the third resonator is a function of a predetermined rejected frequency range.
