Abstract

By applying the magnetic wall concept, compact dual-band and wideband low-profile planar inverted F-L antennas for wireless local area network (WLAN) (2.4 GHz/5.2 GHz) and ultra-wideband (UWB) applications are proposed. The dual-band antenna shows a relative bandwidth of 12% and 10.2% in the ISM-2400 and IEEE 802.11a frequency bands, respectively, at reflection coefficient |S11| ≤ −10 dB. By carefully tuning the geometry parameters of the dual-band design, the two resonant frequencies can be merged to form a wide bandwidth antenna to cover 3,000 to 5,400 MHz (57% relative bandwidth) for a similar reflection coefficient |S11|; this fully covers the lower band UWB (3.1–4.8 GHz) spectrum. The experimental and simulated results in terms of reflection coefficient, gain, radiation efficiency, and field pattern of the two antennas on a small finite ground plane of size 30 mm × 15 mm show good agreement.
