Abstract
The proposed design is composed of simple ultra-wideband (UWB) monopole antenna. The structure consists of semi-rectangular ground plane and rectangular patch on opposite side of the FR4 substrate. In order to achieve ultra-wideband characteristics, half ring-shaped tapered microstrip feed is utilized at the patch. By introducing a square slit at lower edge of the rectangular patch, wide bandwidth can be easily realized. The bandwidth can be further enhanced by creating defect in ground structure. The most impressive feature of the proposed design is its compactness (17 × 25 mm2). Also, this antenna structure has reflection coefficient S11 < −10 dB and voltage standing wave ratio VSWR ≤ 2 in the whole realized band from 2.1 to 15.8 GHz. The overall antenna structure is simulated on substrate having dielectric constant 4.4. The bandwidth of proposed antenna is wide enough to be used in wireless communication applications such as Wi-MAX (3.3–3.8 GHz), WLAN (5.1–5.8 GHz), and X-band communication systems (7.25–7.75 GHz).
