© 2014 IEEE. The design of a 600 MHz non-Foster dipole is presented. The antenna and NIC layout are modeled together using HFSS to include the mutual coupling effects between these two parts. With the formulation developed, the return loss and radiation efficiency of the non-Foster dipole can be calculated and optimized simultaneously in the circuit simulator ADS. The optimized antenna achieves a -10 dB matching bandwidth of 17.5% in simulation, with ka = 0.49. The calculated results indicate that with the non-Foster element acting as an amplifier, a radiation efficiency of over 100% within the frequency band of interest is possible.
