Abstract :
By applying the principle of a dielectric antenna to the microstrip antenna, a novel simple method that can widen the beamwidth and enhance low-angle radiation of a microstrip antenna is presented. Then a novel antenna named the Microstrip-Dielectric Antenna (MDA) is invented. The MDA has three distinct advantages: (1) very wide beams; (2) higher gain at low-angle; and (3) good circular polarization performance within the beams. The principle, design formulas, results and comparison with a conventional microstrip antenna are also presented.
