In this article, the performance of a meander-line-based microstrip patch antenna with split-ring resonator (SRR)-based slots and defected ground is analyzed at the terahertz frequency range. The designed antenna shows a multiband application within a frequency range of 3.77 to 6.60 THz and operates over six different frequencies (viz. 3.83 THz, 4.24 THz, 5.12 THz, 5.50 THz, 5.95 THz, and 6.50 THz). A maximum return loss of 37 is achieved over the band of 5.85 to 6.18 THz, while a maximum realized gain of 7.54 dBi and a total efficiency of 54% is obtained at 4.24 THz. The ground and radiating elements of the antenna are made of gold. Silicon dioxide is used as a substrate material. The antenna simulation is performed and reported in this study. The proposed antenna finds its applications in the detection of colon cancer, skin cancer, brain tumor, drug detection, and communication fields for point-to-point communication purposes.

“…Designed to coexist, these allocations allow up to 10 GHz bandwidth; enough for transmission of multi-gigabit capacities [1]. However, appropriate photoreceiver modules used in wireless communication systems comprise several mmW components such as costly coaxial cables or rectangular waveguide connectors to connect the photodiode with the amplifier and further with the output transition, which results in power losses and bulky module size [2]. Thus, it would be beneficial to integrate such a photoreceiver module within a single device, approaching high-power operation [3], [4].…”

In this work, we present a novel photonic package for high-power photoreceiver modules operating within the E-band (60–90 GHz). The developed Kovar package features a compact size of only 6×3.5×2 cm3 and comprises an optical single-mode fiber (SMF) input, DC bias supply connections and a WR-12 output for coupling out of the radio frequency (RF) signal. As integration platform, a RF laminate submount with implemented planar bias-T based upon grounded coplanar waveguide (GCPW) transmission line circuitry is used for efficient mmW propagation, concluding in a GCPW-to-WR-12-transition. Finite element method (FEM) simulations have been carried out to analyze the frequency range of interest. Besides applied adhesive and wire bonding approaches for assembly inside the package, the RF submount exhibits sections for hybrid integration of single components, e.g. of a high-frequency waveguide photodiode. Optionally, up to two high-electron-mobility-transistor (HEMT) power amplifiers can be integrated within the GCPW circuitry. In addition, the RF laminate is mounted on a brass platform. For uniform thermal expansion within the module, a Peltier element is integrated. Concerning the saturation output power of given HEMT amplifiers, e.g. in the order of +17.5 dBm, corresponding power levels are achievable for packaged devices. For instance, an output RF power of only −19.5 dBm within the 71–76 GHz band is required from the photodiode in conjunction with two cascaded HEMT amplifiers, which results in a total gain of ~37 dB. A small series of the introduced device has been already fabricated. First experimental achievements with in-house fabricated modules will be presented.

Integrated Ψ-Type Photonic Polarization Diversity Receivers for Wireless Radio-over-Fiber Communication Links

In this work, we present novel integrated Ψ-type photonic polarization diversity receivers (PPDRs), comprising two high-frequency 1.55 μm photodiodes (PDs) applicable in wireless radio-over-fiber (RoF) communication links. Therefore, geometries in the overall optical beam splitter (OBS) output section, e.g. optical mode-guiding stripe height, gap between the optical waveguides (WGs), WG widths and coupling length, are considered to obtain high polarization diversity for the developed PPDRs. Moreover, we demonstrate first experimental achievements based on the coupling length variation. In comparison to a conventional 3-dB Y-coupler-integrated device, the experimental results show a polarization-dependent behavior of the PPDR with a maximum polarization dependent loss (PDL) of >3 dB (e.g. measured at the WG-PDs) due to the integrated Ψ-type OBS output section. Taking further geometry parameters of the PPDR into consideration, an increased PDL is expected for the monolithically integrated WG-PDs.
