Abstract
A cavity-backed bow-tie dipole antenna is presented as base station antenna for wide band American and European cellular communication systems (1.7–2.17 GHz). A beam widening of the horizontal plane is achieved by the cavity aperture reduction and the inclusion of a metallic support between the cavity floor and the antenna reflector plane. The structure design procedure is exposed, and a reasonable agreement between simulations and measurements is obtained. Single antenna and medium gain array prototypes have been manufactured and tested. A 35% reflection bandwidth and an 85° to 95° sector coverage is achieved in the desired operation band.
