| () |
| Abstract: |
| By applying the principle of dielectric antenna to microstrip antenna, a novel and simple method that can widen the beamwidth and enhance low-angle radiation of microstrip antenna is presented. And then a novel antenna named Microstrip-Dielectric Antenna (MDA) is invented. The MDA has three distinct advantages:very wide beams,higher gain at low-angle and good circular polarization performance within the beams. The principle, design formulas, results and comparison with conventional microstrip antenna are also presented. |
