Tóm tắt

This paper presents the design of a dual-polarized microstrip patch antenna used for 2.4 GHz WLAN applications. The designed antenna consists of a circular patch fabricated on lowcost FR-4 substrate with a V -shaped slot carved on its surface and a circular 'Petal reflector. The antenna size and positions of the two feeding ports using coaxial cables are optimized to obtain a dual-polarized antenna having resonant frequency at 2.44 GHz, about 8-dBi peak gain, and the isolation between the two ports below -15 dB in the required band. The measured S-parameter results show good agreement with the simulation. The proposed antenna cim be used for 2.4 GHz wireless access points (APs) with 2x2 multiple-input multiple-output (MIMO) antenna systems.
