A Simple Equivalent Circuit Model of Parallel Conducting Strip Arrays

In this paper, a simple equivalent circuit of parallel conducting strip arrays is proposed. The equivalent circuit is a hybrid circuit which consists of a parallel LC circuit and a series inductor. Compared with reported equivalent circuits, the equivalent circuit presented is quite simple, and it is more accurate when the distance between two adjacent strips is close to the operating wavelength. A strip array is simulated in the commercial software and analyzed through the equivalent circuit method. The properties of the equivalent circuit agree well with those of the strip array, which proves the effectiveness and accuracy of the equivalent circuit model.
