Design a Patch Dipole Antenna Array for the Application of Short Baseline Interferometer

This paper designs a patch antenna array for the application of the short baseline interferometer. In this array, reducing the coupling between two patch antennas can be obtained by adding branches to the resonant units. The simulated results show that the bandwidth of this antenna is 2.4GHz–2.5GHz and 5.5GHz–6GHz for S

< −10dB. The isolation S

are below −15dB at 5.5GHz–6GHz. Therefore, this new array has great potential in the applications of short baseline interferometer and direction finding.
