SLOT ANTENNA HAVING SLOTS FORMED ON BOTH SIDES OF DIELECTRIC SUBSTRATE AND CONNECTED THROUGH CONDUCTOR WALLS OR CONDUCTING VIA HOLES

摘要

PURPOSE: A slot antenna is provided to achieve improved gain and radiation efficiency by forming slots on both sides of a dielectric substrate and connecting the slots and ground surfaces through conductor walls or conducting via holes. CONSTITUTION: A slot antenna comprises the first dielectric substrate(101) and the second dielectric substrate(102) laminated on the first dielectric substrate. The first dielectric substrate includes slots(103) formed on upper and lower surfaces of the first dielectric substrate; ground surfaces(104) formed on the upper and lower surfaces of the first dielectric substrate so as to define the slots; and the first connection portion for connecting the ground surfaces formed on the upper and lower surfaces of the first dielectric substrate. The second dielectric substrate includes a feeder line(105) formed at a lower surface of the second dielectric substrate so as to feed electromagnetic field energy; and the second connection portion for connecting the feeder line and the ground surfaces formed at the lower surface of the first dielectric substrate. The first connecting portion and/or the second connecting portion include one or more conducting via holes(106) formed in the dielectric substrates, or conductor walls(107) arranged at side surfaces of the dielectric substrates.
