<p>PURPOSE:To obtain a broad band microstrip antenna by arranging a conductor element in parallel with a radiation conductor element between the radiation conductor element and a grounding conductor, feeding the conductor element through a microstrip line and using a feeder so as to connect the conductor element and the radiation conductor element. CONSTITUTION:The radiation conductor element 1 made of a rectangular open plane circuit is constituted on the 1st dielectric base 11 sufficiently thin in comparison with the wavelength by etching or the like. The ground conductor plate 3 is provided to one face of the 2nd dielectric base sufficiently thin in comparison with the wavelength, and a square conductor element 13 and a microstrip line 14 are constituted to the radiator conductor element 1 on the other side by etching and the conductor element 13 and the radiation conductor element 1 are connected by a feeder 15 at a feeding point 16. The conductor element 13 is connected to the radiation conductor element 1 through the feeder 15 and they are fed, then the conductor element 13 acts like a reactance compensation circuit element to attain a broad band microstrip antenna.</p> |
