Abstract :
In this paper a method of increasing the bandwidth of a shorted patch antenna is presented. To increase the bandwidth, a tilted parasitic radiator is placed over the driven patch. In spite of this, the height of the antenna remained small and the structure is nearly planar. Measurements confirmed a 44 % bandwidth of the input impedance. In that bandwidth the radiation patterns do not change significantly. Simple manufacturing and robust design together with good radiation properties and wide bandwidth make the proposed antenna suitable for present and future wireless communications.
