A compact conical beam antenna composed by a filtering power divider (FPD) and circular open waveguide is presented. In order to reduce insertion loss in Ka‐band, the five‐way radial power divider and the cascaded filters are constructed using metallic waveguides. The filter is based on the principle of the magnetic field inversion characteristics of higher‐order mode resonances, using TE101 and TE102 over‐mode bypass coupling to create a pair of transmission zeros around the passband. A more compact folded structure is obtained by placing adjacent cavities back‐to‐back. Finally, TM01 mode on the circular aperture is excited by the output of the FPD, realising a conical beam radiation pattern. This proposed antenna works at the central frequency of 35 GHz, the maximum elevation angle of θ = 20° and the measured gain of 7.83 dBi have been achieved. The results shows that the impedance bandwidth is 6.29%, from 33.85 to 36.05 GHz. In terms of miniaturisation, the size of the entire antenna is 3.85λ0× $\times $2.51λ0.

“…The quasi-Yagi antenna, as an important planar endfire antenna, has attracted great attention owing to its advantages of having a planar structure and its ease of fabrication and installation [ 1 , 2 ]. The filtering quasi-Yagi antenna integrating the filtering function and endfire radiation can further reduce the size and loss of the system and enhance the integration level of the system [ 3 ]. Although the filtering quasi-Yagi antenna integrates two functions into one component, whether the compact size is really achieved in the filtering quasi-Yagi antenna is one of the important issues.…”

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.
