A novel wideband microstrip-fed end-fire magnetoelectric (ME) dipole antenna element is proposed and exploited. The antenna yields advantages of small size, wide operating bandwidth, low cost, and stable gain. A prototype of the element has a bandwidth (SWR < 2) of 56.7% covering from 24 to 43 GHz with a gain of 4–6.7 dBi. An integrated balun covering the whole operating bandwidth is designed for the feed. A four-element linear antenna array of the antenna elements is implemented using a one-to-four microstrip power divider. The antenna array exhibits an operating bandwidth of 55.4% from 23.5 to 41.5 GHz with a maximum gain of 11.9 dBi. The antenna element and the array can be used for wireless equipment of millimeter-wave communications covering the 28, 37, and 39 GHz frequency band.
