Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G system, such as LTE. Various embodiments of the present disclosure provide a device and a method. To this end, an antenna unit may comprise a dielectric substrate, a dielectric cover on the dielectric substrate, and a slot antenna array formed in a metal layer arranged on or in the dielectric substrate. The slot antenna array may be configured to generate a traveling wave which propagates in the dielectric substrate and the dielectric cover, and may have at least two groups (first and second groups) of slot elements. Each slot element of the second group may be shorter than any slot element of the first group, and slots of the first and second groups may be arranged to be opposite to each other so as to make pairs of slot elements. In a pair of slot elements, the distance from the slot element of the first group to the slot element of the second group may be selected such that a phase shift is provided between 90 degree radiation waves thereof. The pairs of slot elements may be arranged out of alignment such that even-numbered pairs of slot elements are offset from odd-numbered pairs of slot elements.
