A low-cost surface-mount monopole antenna for 2.4-5.2/538-GHz band operation

摘要

A low-cost surface-mount monopole antenna obtained by folding a metallic strip onto a low-profile square-disk foam base is presented. With a compact size of 10 × 10 × 2 mm{sup}3, the antenna can generate two separate wide resonant modes, with the lower mode covering the 2.4-GHz WLAN band (2400-2484 MHz), and the upper mode covering both of the 5.2-GHz HIPERLAN band (5150-5350 MHz) and the 5.8-GHz ISM band (5725-5875 MHz). Good measured antenna gain for operating frequencies across the 2.4/5.2/5.8-GHz bands is also obtained.
