A large-scale, high-gain, high-efficiency, optically transparent grid array antenna operating at millimeter-wave frequencies is proposed in this letter. The grid is employed to mitigate the feeding network loss caused by a lossy transparent conductor, which is composed of a series of rectangular loops directly connected to its neighbors rather than connected through a feeding network. The antenna adopts dual ports and achieves a synthetic gain by anti-phase feeding. By loading rectangular patches on the radiators of the outer region, the radiation and impedance characteristics are improved. A large-scale (5.4 lambda x 5.1 lambda x 0.04 lambda at 25 GHz) array was fabricated using a transparent metal mesh with a sheet resistance of 0.25 Omega/sq. A peak gain of 18.18 dBi, radiation efficiency of 59.6% and optical transparency of 84% were obtained. This antenna provides a valuable solution for large scale optically transparent microstrip array antennas.

This paper introduces a novel high-gain grid array antenna (GAA) based on organic substrate for millimeter wave applications. In order to achieve high gain of antenna unit, a grid array antenna consisting of 7 short sides and 6 long sides was designed. The unit antenna is fed by substrate integrated waveguide (SIW) feeding structure. For further improvement of gain, a 2 x 2 array based on the proposed unit antenna is designed and verified on a three layer organic substrate. The GAA array antenna achieved a simulated maximum realized gain of 15.92 dBi at 223.6 GHz, a 10-dB impedance bandwidth of 6.6%, and 3-dB gain bandwidth of 8.22% at 220 GHz.

A new configuration of a planar grid array antenna for automotive radar applications operating in the 77-81 GHz frequency band is introduced. The proposed array is based on miniaturized loop elements, which are designed to maintain the mutual interelement distance along the azimuthal plane to less than half free-space wavelength, thus allowing a better scanning performance in the final radar system. Moreover, to enhance the gain bandwidth performance, the antenna adopts multiresonant cells realized using variably dimensioned radiation elements. The proposed design was validated experimentally and it is fully compliant with multichannel monolithic microwave integrated circuits (MMICs) designed for automotive radar sensor applications.

A millimeter wave grid array Antenna for fifth generation (5G) communications is presented. The 20 cell, nearly-rhombic, 40x40 mm(2) grid array Antenna structure is simulated and fabricated on a Rogers RT/Duroid 5880 substrate with thickness of 0.25 mm. The grid array has vertical bar S11 vertical bar<-10dB for two frequency ranges in the upper 26 GHz millimeter wave band and has a percentage bandwidth and gain of 5.41% and 16.5 dBi, respectively. The antenna is compared with a Microstrip Patch array using same substrate and dimensions.

A planar substrate integrated waveguide slot-fed microstrip grid array antenna for the frequency range 76-81 GHz is presented. The antenna is realized on a standard soft RF substrate. It is fed using a transverse slot in a substrate integrated waveguide on a separate substrate layer below the antenna. A wideband microstrip to substrate integrated waveguide is designed to feed the antenna. Measurement results show a 12% S11<-10 dB bandwidth.

A wideband planar microstrip grid array antenna is presented. The antenna is realized on a standard Rogers RO3003 substrate. It is fed using two centrally located microstrip vias through a ground aperture. Measured results show a 12% S11 <-10 dB bandwidth and a maximum gain of 17 dBi. Using a variable microstrip line width, a side-lobe suppression of at least -12 dB between 77-85 GHz is measured. The antenna can be used in short and medium range operation for automotive radar.

A cross-mesh array antenna is presented for RF power harvesting in this paper. To enhance the reliability of harvester, producing multiple polarizations and multiple beams is an effective method in rectenna designs. Benefited from the ability of tilting beam angle of cross-mesh array antenna, four differently tilted beams with two linear polarizations can be simply generated by four isolated feed points without any beam forming network design. To demonstrate it, a prototype operating around 6 GHz is fabricated and measured.

This paper presents a novel planar microstrip grid array antenna on low temperature co-fired ceramics (LTCC) with a feeding structure in laminated waveguide technique. The antenna is designed to operate in the 79 GHz frequency range for automotive radar applications. Measured results of a first antenna design show that the antenna is a good candidate for 79 GHz applications and particularly suitable for LTCC integration.
