Bandwidth enhancement of a microstrip line fed printed rotated wide slot antenna with tuning stubs
In this paper, a printed microstrip line fed antenna with a wide rotated square slot, a rotated patch and a pair of tuning stubs is presented. By attaching a pair of tuning stubs to the feedline, bandwidth enhancement for broadband operation can be realized by introducing an additional resonance in the high frequency range. Measured results show that the antenna can operate from 2.38 9.64 GHz with a reflection coefficient less than 10 dB. This is almost twice the bandwidth achieved by the microstrip line fed rotated slot antenna without the tuning stubs. By selecting proper dimensions for the tuning stubs, the antenna can be used for many wireless applications that require wideband and multiband operation.
