DESIGN OF A WIDEBAND PLANAR ANTENNA ON AN EPOXY-RESIN-REINFORCED WOVEN-GLASS MATERIAL (IROKOPASOVNA PLOSKOVNA ANTENA NA EPOKSI SMOLI, OJA^ANI S STEKLENIMI VLAKNI

In this study, the design and prototyping of a compact planar antenna is presented for wideband applications. The designed transmission-line-fed antenna is composed of a rectangular radiating patch and a partial ground plane and is printed on both sides of a 1.6 mm thick, epoxy-resin-reinforced, woven-glass dielectric material. The antenna structure is planar, and its design is simple and easy to fabricate. Compared to the other substrate materials, the proposed antenna on epoxy-resin, woven-glass material could achieve a wider and less-expansive bandwidth. Experimental results show that the designed antenna could achieve an impedance bandwidth (return loss –10 dB) from 2.99 GHz to 18.31 GHz (6.12: 144.33 %). Moreover, the antenna has a good gain and exhibits stable radiation patterns within the operating band. Details of the proposed antenna are presented and discussed.
