Summary:
In this paper, high gain and broad band stacked microstrip patch antenna with a metallic bar and a stacked cavity operating at 40GHz is proposed. The stacked antenna is designed using 4 layers LTCC technology. It can be easily implemented by shorting LTCC substrates to the ground with multiple vias. It is found that both high gain and broadband performance of antenna can be obtained by varying the height of metallic bar and the size of a stacked cavity. The maximum gain and impedance bandwidth of 10dB return loss for the stacked patch antenna with a metallic bar and a stacked cavity are nearly 8.9dBi and 19% (37.3~45.1 GHz) which are 3.8dB higher and 9% wider than 5.1dBi and 10% for the stacked antenna without the metallic bar and the stacked cavity, respectively.
