PLANE ANTENNA

摘要

PURPOSE: To reduce the dielctric loss and to obtain high gains by using a buffer member having an independent air layer to a dielectric substance that is put between a microstrip line conductor and an earth conductor. CONSTITUTION:A microstrip line conductor 8 is obtained by adhering or printing a microstrip line 2 onto the surface of a supporting plate 6 having a small dielectric tangent. An air buffer member 7 has an independent air layer formed by two polyethylene sheets and having an optional size and a space. Then the member 7 is put on the conductor 8 and integrated in one body and then to an earth conductor 3 by adhesion. Thus a plane antenna is obtained. In such a constitution, the dielectric loss is greatly reduced by the member 7 together with high gains secured with this plane antenna.
