An improved design procedure for small arrays of shunt slots (January 1983, Robert S. Elliott): a reprise

摘要

Summary form only given. In 1983, a novel procedure for the design of waveguide-fed longitudinal (shunt) slots was introduced by R.S. Elliott (see IEEE Trans. Antennas & Propag., vol.AP-31, no.1, 68-72, 1983). The author begins with a discussion of the principal differences between the new method and the earlier design procedure which it replaced. An outlined of the development used by Elliott to arrive at a pair of coupled design equations is given. A critical examination of the two design equations which serves to highlight the implications of mutual coupling between radiating elements is provided. Finally, the algorithm suggested by Elliott for array design is revised. Based on the two design equations developed by the author, this algorithm culminates in the required length/offset couplet for each slot in the array subject to a desired set of excitation coefficients and input match requirements.
