Dual-frequency microstrip antenna with inserted strips |
摘要 |
A dual-frequency microstrip antenna has three strips of bare low-dielectric material alternating with two strips of copper-clad (one side) high-dielectric material bonded close together on a copper plate having a feed inserted therethrough. A copper-claded layer (one side) low-dielectric material is placed over the five strips and bonded simultaneously. The inner strips separate the region of high-dielectric constant from the region of low-dielectric constant. The microstrip antenna is considered to be a lossy resonating cavity enclosed by a perfect electric conductor and by a perfect magnetic conductor.
