“…At resonance frequencies, the bioinspired flower-shape antenna presents gain very close to the one observed in the circular-shape, with a difference of 1.04 dBi, however, with the insertion of one more element of same dimension, there is an increase in the power gain (3.11 dBi), which shows an expected behavior for an antenna array [5], which results in a maximum gain of 8.83 dBi. The gain observed in the aperture-coupled antenna is compatible with that shown in other works for the 60 GHz frequency range, where gains of 3 to 14 dBi can be verified depending on the type of coupling structure used [22][23][24].

“…In [22] it was developed balanced-fed and fork-fed aperture-coupled patch antennas with one, eight and sixteen elements arrays suitable for broadband millimeter-wave communications at 60GHz, with a gain of 8 dBi for a single element and 17 dBi for a 16-elements array. In [23] it was proposed a 4x4 aperture-coupled patch antenna array with peak gain reaching 21.4 dBi at 60 GHz band. A low-cost aperture-coupled patch antenna, using the standard printed circuit board (PCB) process, was proposed for the 60-GHz-phased array antenna in [24], with measured peak gain of 6.9 dBi at 62 GHz for the single antenna, and measured peak gain from 4 to 7.5 dBi across all four IEEE 802.15.3c channels, for each antenna element, within the frequency range from 57.2 up to 64.5 GHz.…”

A flower-shape bio-inspired aperture-coupled antenna array for on-chip application, generated by Gielis formula, operating in industrial, scientific and medical (ISM) band at 60 GHz (57 GHZ to 64 GHz) is presented in this paper. The antenna proposed is composed of a transmission feed line followed by an aperture and patch element built in aluminum, with 2 micrometers of thickness, lying on two layers of silicon with 200 micrometers of thickness each. Dimensions of the antennas were calculated according to the effective wavelength for the resonance frequency at 60 GHz. Simulations were performed in the commercial software ANSYS® Electronics Desktop. The use of the bio-inspired flower-shape promotes more compact structures with greater perimeter, rearranging these shapes into an antenna array provided a gain and a bandwidth increase in the design, 3.11dBi and 2.86GHz, respectively, which resulted in a maximum gain of 8.82 dBi and a total bandwidth of 5.88 GHz.

“…A 4 × 4 array composed of complementary ME-dipole antenna elements is excited by a low-loss T-junction SIW feeding network, a gain up to 19.6 dBi and a wide bandwidth of 22.6% can be simultaneously achieved [5]. Furthermore, a 4 × 4 array composed of cross patch elements that are surround by rectangular cavities is fed by a slotted SIW network, a peak gain up to 21.4 dBi in the frequency bands of 56-63.1 GHz is realized in [6]. However, both of them only realize a single polarization, which cannot enhance the system capacity with a compact size.…”

A dual linearly-polarized (LP) high-order-mode antenna with high gain and high isolation is proposed for 5G millimeter-wave (mm-wave) applications. To obtain high gain and wide bandwidth, a 2 × 2 slot-fed magneto-electric (ME)-dipole antenna elements are excited by a high-order-mode TM 430 cavity. Two substrate integrated waveguide (SIW) feeding networks that are vertically arranged in the bottom layers are employed to feed the high-order-mode cavity antenna for a double capacity, high isolation and low transmission loss. Moreover, an 8 × 8 antenna array is fed by a pair of compact modified H-shaped full-corporate SIW networks. Measurement results show that an overlapped frequency bandwidth of 14.6% (36.8-42.6 GHz) with a peak gain of 25.8 dBi and an isolation of greater than 45 dB for the 8 × 8 dual LP antenna array are achieved, which guarantee reliable high-speed data transmission and anti-interference capacity for 5G communications. INDEX TERMS Dual polarized, high-order mode, 5G millimeter-wave applications, high gain, high isolation.

A millimeter‐wave broadband E‐plane out‐of‐phase power divider integrated with transition from a rectangular waveguide to substrate integrated waveguides (SIWs), is proposed. Two SIW cavities and two I‐shaped coupling apertures are used to achieve out‐of‐phase or differential signal division with broadband impedance matching. Owing to the symmetrical structure, a pair of differential signals with a phase difference less than 180° ± 0.1° and an amplitude imbalance less than 0.01 dB can be achieved. For measurement, a back‐to‐back test is fabricated and measured in Ka‐band by multilayer PCB fabrication process. The experimental results show that the insertion loss of a single transition is less than 0.65 dB within the 10‐dB impedance bandwidth from 26.9 to 38.6 GHz.
