| Abstract: | The Characteristic equation of cavity-backed slot array is formulated, using the spectral domain approach and the concept of transmission line. Consider narrow slot, then, the formula is consistent with [3]. The basic antenna parameters are given, for example power transmission coefficient, input voltage standing-wave ratio (VSWR), quality factor, radiation field and directivity. The power transmission coefficient is calculated as a numerical example. |
