We demonstrate antenna-coupled spintronic terahertz (THz) emitters excited by 1550 nm, 90 fs laser pulses. Antennas are employed to opti-mize THz outcoupling and frequency coverage of ferromagnetic/nonmagnetic metallic spintronic structures. We directly compare theantenna-coupled devices to those without antennas. Using a 200 µm H-dipole antenna and an ErAs:InGaAs photoconductive receiver, weobtain a 2.42-fold larger THz peak-peak signal, a bandwidth of 4.5 THz, and an increase in the peak dynamic range (DNR) from 53 dB to65 dB. A 25 µm slotline antenna offered 5 dB larger peak DNR and a bandwidth of 5 THz. For all measurements, we use a comparatively lowlaser power of 45 mW from a commercial fiber-coupled system that is frequently employed in table-top THz time-domain systems.
