| Abstract |
The radiation characteristics of an array antenna are affected by the distance between radiating elements. When the distance between radiating elements is increased, the half power beam width is decreased, thus, the directivity of an array antenna is increased. However, when grating lobes(except main lobe) are included in visible region according to increase the distance between radiating elements, the directivity is dereased. Therefore, an array antenna has the threshold for the distance between radiating elements. In this paper, we analyze the radiation characteristics for a dipole antenna with parasitic element, and studied the improving method of the radiation characteristics for a dipole array antenna using parasitic elements in the condition over the threshold. |
