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.

“…In addition, some of the recently reported pencil beam filtennas that achieve filtering functionality through substrate integrated waveguide (SIW) technology or full-metal structures are introduced in refs. [20][21][22][23]. However, these filtennas can still be improved in terms of frequency selection performance.…”

“…As shown in Fig. 28, in [111], the structural length LSPP of ESPPs mainly affects the out-of-band suppression of the filter, and the bandgap between the ESPPs causes the stopband performance of the filter. The width of SIW and the filling dielectric can control the start frequency of the working band.…”

In recent years, with the rapid development of integrated circuits, the filtering antenna (FA) circuit of the substrate integrated waveguide (SIW) has attracted widespread attention in wireless communications. Numerous structures have been proposed to improve the performance of SIW FA. Hence, this paper presents the development and miniaturization trend of the SIW FA, and briefly introduces the structure and historical development of the SIW FA. In terms of the mode, multi-mode cavities and incomplete mode cavities are constructed. Multi-layer structures, special structures and the slow-wave technology are constructed in physical structure. Several methods and design examples of the SIW FA miniaturization are introduced from these two aspects. Based on the combination of the filter and antenna, the FA remains the advantages of the SIW structure, mainly including small size, low insertion loss, high quality-factors, and easy integration in planar radio frequency components. Therefore, it can further reduce the circuit, allowing SIW FAs to be applied in many aspects such as the 5G (5th generation mobile communication technology) and wireless local area network communications.INDEX TERMS Substrate integrated waveguide (SIW), filtering antenna (FA), multi-mode, incomplete mode, multi-layer, slow-wave technology.

“…Antennas and filters are circuits at the wireless front end that were traditionally parted. However, nowadays, the integration of the two circuits what is known as a filtering antenna is widely researched [1][2][3][4][5]. A filtering antenna adds a radiator with a selectivity feature, which is represented by a flat gain within the operational bandwidth and two radiation nulls at the upper and lower frequencies.…”

In this paper, filter and antenna integration is studied to produce a compact device for wireless front-end equipment. Filtering antennas are advanced due to their selectivity performance, represented by a flat gain response. Two filtering antennas are proposed to improve the selectivity using different orders. The first antenna is based on second-order filter and the other on third-order filter. Both antennas are designed to operate at 4.65 GHz for mid-band 5 G application with a bandwidth of 6.45%. The first antenna integrates a rectangular radiator and an interdigital resonator based on second-order filter. It obtained a bandwidth impedance of −10 dB for 300 MHz and a maximum gain of 6.48 dBi. Meanwhile, the second design consists of a rectangular radiator and two interdigital resonators based on third-order filter as the feedline. Having the same bandwidth as the first design, the second design achieved a flat gain of 6.37 dBi in the operational bandwidth. The second antenna design showed better selectivity with sharper gain than the first design. The two antennas were fabricated and measured for validation. The simulation and measurement results showed good agreement.
