Circular microstrip antenna for polarization and radio communication apparatus including the same

摘要

It possesses dielectric base substance 2, forms only the emission electrode 3 for circularly polarized wave occurrence on the surface of this dielectric base substance 2. As signal railroad track 4 of the kopurena railroad track for emission electrode supply of electricity is formed, the dielectric base substance back which avoids the formation territory of that signal railroad track 4 gland electrode 5 is formed extensively on back of the dielectric base substance 2. As for signal railroad track 4, from the back edge 7 of dielectric base substance 2, the form which it was expanded was formed it has formed to the halfway position which faces to the emission electrode central position O in dielectric base substance back 2b. Improvement of circularly polarized wave quality being easy, it can hold down production cost, furthermore, the microstrip antenna for the circularly polarized wave whose miniaturization is easy it can offer.
