- Abstract
- The paper presents a microstrip patch array antenna for transmitting (Tx) and receiving (Rx) in the Ku band. The patch array antenna has horizontal polarisation for the Rx band and vertical polarisation for the Tx band. The element of the patch array antenna was designed as a three-stacked structure consisting of one radiation patch and two parasitic patches for high gain and wide bandwidth characteristics. The unit elements were arranged in a 1×8 array using a mixture of series and parallel feeds. To verify the practicality of this antenna, a three-stacked patch array antenna was fabricated and its performance was measured. The gain of the array antenna in the Rx and Tx bands exceeded 17 and 18dBi, respectively. The impedance bandwidth was over 10 in both bands. The cross-polarisation level was below -25dB, and the sidelobe level was below -9.4dB.
