Abstract
A semi-circle-fed microstrip patch antenna is presented in this paper. The proposed antenna is found to have a much broader impedance bandwidth when compared with the conventional L-slot antenna. The proposed antenna is able to achieve an impedance bandwidth of 63.7% for Voltage standing wave ratio (VSWR)<2, centred at sime6 GHz. To the author´s knowledge, this reported bandwidth is by far the largest achievable through the probe proximity coupled technique. A comparison between rectangular-shaped patch antenna and stub patch antenna using the same excitation mechanism is given
