This paper proposes a design of two-ports circularly polarized stacked patch antenna with square ring slot feeding technique for multiple-input-multiple-output (MIMO) application. The antenna with a quarter-wavelength slot and chamfering patch., which radiates at 2.4 GHz., occupies an overall area of mathbf{96} *mathbf{96} *mathbf{42 mm}^{mathbf{3}}. The 7.6-dBic gain antenna prototype presents an axial ratio lower than 0.4 dB in the operating frequency band (2.4 to 2.485 GHz) as well as a port isolation higher than 27 dB. Therefore., this antenna demonstrates good port-to-port isolation., axial ratio (AR) as well as a compact dimension and is suitable to be used in systems that operate in a wireless local area network (WLAN) frequency band.

Abstract
This paper proposes a design of two-ports circularly polarized stacked patch antenna with square ring slot feeding technique for multiple-input-multiple-output (MIMO) application. The antenna with a quarter-wavelength slot and chamfering patch., which radiates at 2.4 GHz., occupies an overall area of mathbf{96} *mathbf{96} *mathbf{42 mm}^{mathbf{3}}. The 7.6-dBic gain antenna prototype presents an axial ratio lower than 0.4 dB in the operating frequency band (2.4 to 2.485 GHz) as well as a port isolation higher than 27 dB. Therefore., this antenna demonstrates good port-to-port isolation., axial ratio (AR) as well as a compact dimension and is suitable to be used in systems that operate in a wireless local area network (WLAN) frequency band.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
