摘要: Abstract A novel and simple wideband dual-frequency design of a coplanar waveguide (CPW)-fed triangular planar monopole antenna is proposed. By the proper choice flare angle for patch gap distance CPW feeding structure, an additional resonant mode wide impedance matching can be realized. Both theoretical experimental results bandwidths radiation characteristics prototypes proposed have been presented discussed. The measured - 10 dB bandwidth at lower band (1.71 GHz) about 240 MHz that upper (5.62 GHz) reaches 2 GHz, which cover DCS1800 IEEE 802.11a 5.2/5.8 GHz WLAN standards, respectively. Good monopole-like patterns with gains 2.3–3.6 dBi 3.9–5.6 dBi over bands, respectively, also obtained.
