Abstract

An omni-directional monopole antenna is proposed in which a radiating element 3 and an elongate microstrip line 7 are provided one side of substrate 1, and a ground plane 5 on the opposite side. The radiating element 3 is a printed patch with a single slot 9 on one side of the radiating element 3. The position of the slot 9 is selected to provide a sufficiently wide impedance bandwidth and improved omni-directional radiation patterns in the elevation (y-z plane) direction in a desired range of operating frequencies. The slot 9 is spaced from a centre line of symmetry of the antenna by about 0.25 [err], where [err] is the wavelength in the substrate corresponding to the centre frequency of the bandwidth of the antenna. The radiating element 3 is preferably circular or elliptical, although a square or rectangular element is also possible, and the slot 9 is about half as wide as the microstrip line. [Fig. 1(a)]
