	abstract = {A miniature (30 {\texttimes} 10 mm2) efficient planar monopole antenna with stable radiation pattern for UWB applications (3.1-10.6 GHz) is proposed in this paper. These characteristics, wide bandwidth and radiation stability, are achieved by using original design solutions with maintaining a small size and good efficiency of the system. Based on modified ground plane and loop feeding structure, the first design solution consist to propose a simple technique which not requires any discrete additional elements or circuits and does not affect the overall dimensions of the basic structure. This technique enhances the (-6 dB) bandwidth of the planar monopole antenna by approximately 50\% compared to the basic structure while maintaining the same dimension (30 {\texttimes} 10 mm2). The optimized proposed antenna presents a large bandwidth, good radiation stability, total efficiency higher than 70\% over the entire band and small size (30 {\texttimes} 10 mm2) which will enable to use it in different UWB applications. In the second step, two L slots are added in the printed circuit board of the proposed UWB antenna to reach a good stability of the radiation pattern on the overall desired band.},
