A novel application of the Planar Inverted-F Antenna (PIFA) is shown for operation as an element for a tightly coupled array. 3:1 impedance bandwidth is demonstrated at millimeter wave frequencies, with VSWR < 2.5 from 15–45 GHz. The proposed configuration has only a single substrate and superstrate matching layer. The array is designed for a 75-ohm feed through the ground plane. An additional matching section made through the bottom ground plane is utilized for matching to 50 ohms. Performance analysis is conducted on the unit cell using Ansys HFSS's frequency domain solver and CST Microwave Studio's time domain solver. Further demonstration is performed with a 4-by-4 finite array, where reasonable central-element match and realized gain is obtained.
