Description

In this letter, radiation pattern of a dipole array antenna coupled to a two-wire transmission line is numerically investigated. The effect of array spacing on the main beam direction of the array antenna is shown. In addition, it is shown that the endfire radiation of the array antenna can be suppressed when series inductors are loaded with the two-wire transmission line.
