摘要：

A novel compact ultra-wide band antenna with L-shaped slot is presented. The printed antenna is fed by a microstrip feed line to achieve impedance matching for the SMA connector. The proposed antenna offers 118% bandwidth when printed on a substrate of dielectric constant 4.4 and has an overall dimension of 23.7 x 23.7 x 0.8 mm(3). The simulated and measured reflection characteristics of the antenna with the variation of key-parameters along with radiation patterns of the final antenna are presented and discussed. In addition, by decreasing the dimension of radiating patch, band-notched properties in the lower wireless local area network (WLAN) (5.15-5.35 GHz) or higher WLAN (5.725-5.825 GHz) bands are achieved. With the compact size and broadband, this antenna is very suitable for using in a trade-off which has to be taken account for a design of miniaturisation.
