Abstract :
A novel slot antenna with a large bandwidth and small size is introduced, which is fed by a fan-shaped microstrip feed with a straight stub. The effect of the fan feed on the impedance characteristics is investigated theoretically and experimentally. Good agreement between theoretical results and experimental ones is obtained. Its measured VSWR ≤ 2 bandwidth reaches approximately 114%, covering 1.55 GHz - 5.66 GHz . The measured standing-wave ratio curves and radiation patterns of the antenna at f = 2 GHz and at f = 5 GHz both are presented.
