摘要：
The narrow bandwidth of a microstrip antenna is one of the important features that restricts its wide usage, although it possesses many advantages such as low profile, light weight, etc. Various techniques have been used to enhance the bandwidth of this kind of antenna. This paper presents a planar microstrip array designed by the log-periodic technique for wideband operation in the frequency range of 1.7–5.5 GHz. The elements of the array are orthogonal patches, aperture coupled fed by a microstrip line. The far-field pattern of the array, for a number of frequencies in the above range, has been computed by a simulation procedure.
