Abstract
In this paper, a 2 × 8 elements ultra-wideband tightly coupled dipole antenna array is presented. The array is constructed by placing alternate dipole elements on the opposite sides of a substrate. The array is designed to operate in the FCC frequency band for ultra-wideband (3.1 GHz to 10.6 GHz) wireless communication. The mutual coupling between the elements in the proposed array is high and it is used to enhance the performance of the array. An ultra-wideband 175 Ω to 50 Ω parallel strip to microstrip line transition is used as a balun and impedance transformer in the proposed structure. In the proposed array good input impedance match is achieved along with good radiation characteristics throughout the band of interest. The overall size of the array is 240 mm × 120 mm × 58.5 mm.
