E. bandpass and bandstop filters are separately designed. In addition, the approach presented in the previous section is based on analytical and optimization procedures, whilst the method presented here is significantly simpler. Although it is very simple and offers straightforward and efficient realization, this method has been rarely used for multi-band filter design and only dual-band and triband filters have been realized using this approach. The reason for this lies in the fact that most aspects do not make this method very favorable in comparison to others.

E. two modes that have the same resonant frequency but orthogonal field distributions. 14(a). The upper side and lower side of the cavity are modeled as the electrical wall, whilst its lateral sides are modeled as magnetic walls. The electromagnetic field in the cavity is defined by TMmn0z modes ∞ X ∞ mπ  nπ  X x cos y , Amn cos a a m¼0 n¼0 ! 9) Design by using multi-mode resonators 21 where Amn is the magnitude, ω frequency, a effective width, and εeff permittivity. 10) þ f mn0 ¼ pffiffiffiffiffiffiffiffiffi 2π μεef f a a It can be seen that there is an infinite number of resonant frequencies with different field distributions.

In that way, a very strong coupling between the two modes is achieved and they are positioned at distant frequencies. The realized dual-band filters are the second-order filters, and they are characterized by good in-band performance. However, the selectivity of the passbands is poor. A disadvantage of these three configurations is the fact that positioning of passbands is determined by the coupling between the two modes and is thus very limited. 25λg represent further drawbacks. A second way of applying dual-mode behavior is the realization of two passbands using higher-order modes.
