“…The second kind consists of loading a piece of graphene nanoplate as a tunable resistor to the feed line to obtain the gain manipulation function [ 22 ]. The third kind consist of adding a resistor in the low frequency current path [ 23 , 24 ] or adding a resistor-terminated inductor [ 25 ] to absorb the low-frequency single, resulting in improved impedance matching at the low side of the operating band. The last kind is the filtering endfire antenna [ 26 ] or patch antenna [ 27 , 28 ] with a resistor-terminated structure.…”

In this paper, a compact quasi-Yagi antenna with embedded resistor-loaded arms is proposed to obtain a filtering response with four radiation nulls. The embedded resistor-loaded arms achieve two additional radiation nulls caused by reverse currents and absorb the unwanted out-of-band resonant points brought by themselves. The director close to the driver provides a resonant point and a radiation null caused by opposite currents between the driver and the director. Compared with other filtering quasi-Yagi antennas, the proposed one can achieve a filtering response with a compact size along the endfire direction. For demonstration, a balun-integrated prototype covering the 5G band N78 (3.3–3.8 GHz) is designed with the size along the endfire direction (without ground) of 0.13 λ0 (λ0 is the wavelength in the free space at center frequency), and the measured results show a 10 dB impedance-matching bandwidth of 22.9% (3.21–4.04 GHz), four radiation nulls, and a peak gain of 4.73 dBi.
