Design of a Wideband Dual-polarized C-band Microstrip Antenna Array
This paper presents the design of a wideband dual-polarized microstrip antenna array working at C-band. The antenna adopts a multi-layer structure using additional parasitic patch, in order to achieve better port isolation and wide-band characteristics. The 1*4 array antenna is simulated and optimized, which is fed by the coplanar microstrip lines. The results show that the VSWRs of the antenna ports are less than 2 in the frequency range of 4.9 GHz to 6.1 GHz, with a relative bandwidth of about 21.8%. The designed antenna also has a gain of over 13.4 dB at the frequency of 5.5 GHz.
