Abstract�� An improved novel planar shorting structure broadband monopole antenna was presented. In the light of planar structure easily conformal to substrate, the special shape structure and the technique of load-adding, this kind of antenna realizes the miniaturization and has a better bandwidth and radiation compared with the conventional monopole antenna. The theoretical parameters analysis of the main structure and simulation results with high frequency structure simulator(HFSS) show that the antenna satisfies the conditions of voltage standing wave ratio(VSWR) less than 3, vertical polarization, horizontal omni-directional radiation, radiation gain no less than -10��dB and radiation smoothness below 2��dB, on the work frequency band ranged from 30~88��MHz. The antenna has a wide application in vere high freqwency(VHF)communication system. The calculational results derived agree well with the experimental results.
