A high-selectivity filtering magnetoelectric (ME) dipole antenna based on rectangular micro-coaxial lines (RMCLs) is presented, fabricated using micro-metal additive manufacturing (M-MAM) for V-band operation. The structure integrates two λ/4 resonators, one λ/2 resonator, and an ME dipole antenna, coupled through J/K-inverters realized as RMCL gaps and short-circuited stubs. Notably, while a standalone ME dipole inherently supports an impedance bandwidth over 30%, this design achieves a 5.04% operating bandwidth centered at 59.5 GHz after integrating filtering functionality. Simulations confirm a peak gain of 4.53 dBi within the passband, with cross-polarization consistently below −20 dB. A sharp gain roll-off to −10 dBi at 1.048f0 and 40 dB out-of-band suppression demonstrates exceptional frequency selectivity. Owing to inherent miniaturization, lightweight construction, and low-loss characteristics, the antenna exhibits significant potential for low-earth-orbit (LEO) satellite internet systems.
