“…Furthermore, if the lens is thick, manufacturing difficulty increases. Thus, conventional methods make lens antennae bulky [8], [9], [10], [11] because of the need for several thicknesses and layers to realize the desired features and performances of their applications.…”

This study proposes a dielectric lens antenna that implements an impedance matching layer comprising square-pillar periodic structures on the lens surface to reduce the surface reflection formed in the lens from a high-permittivity dielectric material. To ease the fabrication process, the matching structures (MS) implemented on the lens surface are made of the same dielectric material as the dielectric lens through microfabrication structure. The dimensions of the square-pillar periodic MS unit cell are optimized for its period, space occupancy ratio, and height using periodic boundary simulation, considering the plane wave incident. Electromagnetic simulations and experiments to evaluate the effectiveness of the optimized square-pillar periodic MS were conducted. Implementing the square-pillar periodic MS to a lens composed of modified-polyphenylene ether (modified-PPE) with a relative permittivity of 5.34 assists in reducing the surface reflection inside the lens compared with the lens without anti-reflection and improves the peak gain by approximately 2 dB from 250 to 290 GHz.

“…Eband backhaul point-to-point radio links at 71/76 GHz and 81/86 GHz can deliver up to 10 Gbps even in a dense urban radio environment [1]. To fulfil this requirement, high-gain antennas (above 38 dBi) with enough side-lobe suppression [2], and waveguide diplexers to separate the transmit and receive channels in the transceiver front-end have to be used [3]. The waveguide diplexers must feature high isolation between bands and low insertion loss.…”

This paper presents the design and realization of a high-yield tuning-less waveguide diplexer and a high-gain lens horn antenna for 5G point-to-point fixed-beam communications at the frequency ranges of 71/76 GHz and 81/86 GHz (E-band). The diplexer is composed of two bandpass filters based on the combination of a low-pass filtering function and a high-pass structure. The diplexer provides very relaxed fabrication tolerances. A prototype has been fabricated and measured showing return loss better than 20 dB and attenuation levels higher than 60 dB. The insertion loss is better than 1 dB. A lens horn antenna which provides more than 38 dBi gain is utilized to provide high directivity at the same frequencies. The proposed sub-system combines the advantages of high-performance and simple mechanical assembly finding, it especially attractive for 5G applications due to the reduced fabrication cost.
