MICROSTRIP PATCH ANTENNA FOR SMALL SIZE REPEATER

摘要

PURPOSE: A microstrip patch antenna for a small repeater is provided to eliminate height restrictions of a jig where a repeater is located, thereby miniaturizing an indoor repeater. CONSTITUTION: A microstrip patch antenna comprises a donor antenna(100), a service antenna(200), and an aluminum jig(300). The aluminum jig is located between the donor antenna and the service antenna. The donor antenna comprises a plurality of ground surfaces, a dielectric substrate, a radiator, a parasitic dielectric substrate, and an aluminum wall. The ground surfaces are arranged on the upper surface of the aluminum jig and the lower surface of the dielectric substrate respectively. The radiator is arranged on the upper surface of the dielectric substrate.
