N2 - A 7-port microstrip grid array is firstly presented in this paper, showing sufficient design flexibility to configure the large microstrip grid array into one or two unbalanced antennas as well as one or two balanced antennas. As an example, we designed and fabricated the 7-port microstrip grid array of 145 radiating elements in RT/duroid 5880 substrate with a size of 100×100×0.381 mm3 for 24-GHz applications. The measured results show that the 7-port microstrip grid array has achieved excellent performances: 1.57% impedance bandwidth, 4.51% gain bandwidth, and 25.15-dBi gain at 24.12 GHz as an unbalanced antenna, 2.11% impedance bandwidth, 4.80% gain bandwidth, and 25.36-dBi gain at 24.09 GHz as a balanced antenna, and 3.06% impedance bandwidth, 5.42% gain bandwidth, and 25.82-dBi gain at 24.73 GHz as two balanced antenna. The proposed structure can also operate as MIMO antennas with envelope correlations between radiation patterns of the two antenna elements lower than-30 dB over the 10-dB input impedance bandwidth of the proposed structure.
