Abstract:
A novel folded monopole antenna is investigated numerically and experimentally. The
proposed antenna comprises a short folded monopole suitably shaped at the base with two vertical
grounding probes. This small antenna is shown to have a fractional impedance bandwidth up to
125%(1.6GHz to 7.5GHz) for a 10dB return loss.An interesting compromise between impedance
bandwidth and pattern control is found by tuning a double side bevel at the base of the monopole,
the position of the feeding point and its distance from the ground plane. Measurements and
simulations are in good agreement and show a dramatic improvement in terms of impedance
bandwidth compared with planar and L-shaped monopole antennas. Impedance and radiation
characteristics make this novel folded monopole antenna a remarkable candidate for indoor
applications where the wideband coverage of different systems is required. The working bandwidth
covers a large number of wireless communication systems including GSM 1800, Personal
Communication System (PCS1900), Universal Mobile Communications System (UMTS), the
2.4GHz (2400–2484MHz) and 5.2/5.8GHz (5185–5350/5725–5875MHz) bands for WLAN
communication, Wireless Local Loop (3.4–3.6 GHz), the US-NII bands and the lower bands
allocated to ultra-wideband communications.
