Table 3 presents the comparison of the proposed parasitic patch array antenna in different literatures. 4,10,11 The parameters including number of layer and patch, the size of the antenna, the impedance bandwidth and the peak gain are taken into account. From the table, we can see that the 5 3 5 CPPS-based array antenna has the advantages of simple structure, wide bandwidth and high gain. | C ONCL US I ONThis article presents a design of a 5 3 5 array antenna based on coplanar parasitic patch structure. A feed network is formed via dual ports stimulating the two center patches and resonance branches between the central patches and the parasitic patches. The designed array antenna has a simple structure, high gain, strong orientation, and low crosspolarization. It has good reference value to the array antenna research. Therefore, it has important applications in communication and radar system.
