In this communication, a hybrid shaped wide slot antenna with hybrid parasitic element has been investigated which is fabricated on an FR-4 substrate (tan(δ) = 0.02, εr = 4.3). The mutual coupling (between the slot and tuning stub), tuning of resonating modes and bandwidth of the antenna are adjusted by changing the dimension of parasitic element and tuning stub. The measured fractional bandwidth of the proposed antenna is 146.82% for S11 < −10 dB which covers the frequency span from 0.92 to 6 GHz. This antenna exhibits resonances at 1.094, 1.56, 2.073, 2.67 and 4.02 GHz. Surface current distribution has been investigated, and series of equations are deduced for resonating frequencies. Radiation characteristic exhibits an eight-shaped pattern at fundamental mode frequency whereas at frequencies 2.85 and 3.91 GHz a distorted pattern has been observed. For understanding the behavior of the antenna, structural parameters are varied in specific ranges.
