Analysis of a u-slot patch using characteristic mode analysis and coupled mode theory
Borchardt, John J.; Lapointe, Tyler C.
Patch antennas incorporating a U-shaped slot are well-known to have relatively large (about 30%) impedance bandwidths. This paper uses Characteristic Mode Analysis to show a classic U-slot patch geometry supports in-phase and anti-phase coupled modes that occur within Coupled Mode Theory.
