(a) Photo of the fabricated LWA prototype biased with an external magnetic field of H 0 = 1900 ± 150 Oe. (b) Measured TX and RX gain patterns at port 1 and as a function of frequency, with port 3&4 terminated at 50 Ω. (c) Scanned TX antenna pattern at port 1 by changing the external bias field H 0 by ±50 Oe.
