Abstract :
A square slot antenna using a coplanar waveguide (CPW) feed with a widened tuning stub for broadband operation is studied. The impedance matching for the proposed antenna is mainly affected by the location of the tuning stub in the square slot, and the impedance bandwidth is mainly determined by the size of the tuning stub. By properly choosing the location and size of the tuning stub, a wide impedance bandwidth of 60% can be obtained, which is about 1.9 times that of a conventional CPW-fed square slot antenna with a simple tuning stub.
