“…Freq consumption (P DC ) is higher comparing to those designs implemented in the CMOS technologies, a nice linearity performance is obtained within the advantage of GaAs technology. As for the T/R modules adopting GaAs-based MMICs, 26,27 the proposed work has exhibited a better power performance at both operating frequency bands. Although additional losses have been induced by the interconnects, the proposed work still demonstrated a comparable result with the single chip solution reported in.…”

SummaryIn this paper, a dual‐band antenna switch module with switching capability targeting the inter‐band carrier aggregation at 5G new‐radio (NR) frequency range 2 (FR2) is presented. Inter‐band carrier aggregation has become increasingly prevalent in millimeter‐wave applications at Ka‐band frequencies as a means to secure sufficient bandwidth for improving the rate of data transmission. Antenna modules with polarization switching capability are considered as a critical component for maintaining proper transmission and reception of the signals at millimeter‐wave frequencies. The integrated system consists of a wideband single‐pole‐double‐throw (SPDT) switch and a dual‐band power amplifier (PA) that are realized on the Rogers RO3010 substrate. With the two double exponentially tapered slot antennas (DETSA) arranged in the mutually orthogonal configuration, the antenna switch module can provide linear polarization at ±45 degrees. A measured error‐vector‐magnitude (EVM) of −30.3 dB at 38 GHz using 200‐MHz standard 5G NR 256‐QAM orthogonal frequency‐division multiplexing (OFDM) modulation has demonstrated the feasibility of the proposed module to be implemented for millimeter‐wave applications.

“…Targeting long-term operation, the durability test was suggested to be performed for integrated modules. 27 Figure 11 shows the 3-m OTA test setup for the evaluation of the durability of the proposed antenna switch module. Two horn antennas were located by aligning the beam of the two DETSA antennas.…”

In this paper, a compact low-profile dual-band wearable textile antenna is proposed for on-body and off-body communications. The presented antenna works efficiently in the 5G n79 frequency band (4.4 − 5 GHz) and the ISM band (5.725 − 5.875 GHz). The designed antenna has an ultra-wide impedance bandwidth of 2.01 GHz and peak realized gains of 10.5 dBi and 12 dBi at 4.5 GHz and 5.8 GHz, respectively. The antenna has a small footprint (π × 0.3λ02), which is inspired by circular fractal geometry. The performance of the presented wearable antenna is evaluated at various body parts, including the arm, wrist, and chest. The link margin is evaluated in the on-body and off-body communication scenarios, i.e., communication with the implantable antenna and the outside-body antenna, which is 80 dB and 65 dB at 4.5 GHz and 5.8 GHz, respectively. The 1 gm/10 gm specific absorption rate values at 4.5 GHz and 5.8 GHz are 0.12/0.098 and 0.11/0.082, respectively, which are significantly lower than the standard values, making the proposed antenna suitable for modern wearable applications.

“…Another reason for the high cost is the complex design using expensive dielectric substrates such as Roger RT/duroid. Several ways have been proposed for designing a Vivaldi antenna, but the most common is a planar structure printed on a dielectric substrate [18]- [21]. Even though antennas fabricated using these previously proposed methods have a high gain and a wide frequency range, they can be hard to feed and expensive to fabricate, especially when they are made of solid metal.…”

This paper presents the design of fully metallic 3D Vivaldi antenna that can be used for wireless power transmission applications. The 3D antenna consists of 1) a tapered profile, 2) a rectangular cavity, and 3) a horizontal slot cut that is used as a transition between the cavity and the tapered profile. The proposed antenna design is fabricated using two distinct approaches, the first of which is a 3D metal additive manufacturing (AM scheme) with a sequential material layer addition technique. The second version is based on the CNC milling (CNCM) technique implemented by selectively removing material in a controlled way. The measured gain of the AM and CNCA-based 3D Vivaldi antenna is 4.95 dBi, and 5.70 dBi, respectively. The measured bandwidth (BW) of the AM-based 3D antenna is 4.70 GHz (fractional BW (FBW) of 52.86%), whereas the CNCM-based 3D antenna is 4.95 GHz (FBW of 56.73%). Measurement outcomes indicate that the CNCM version of the 3D Vivaldi antenna is ∼ 1.2x more effective than the AM version in terms of realized gain and can be used for metal-based antenna system power telemetry due to its high gain and wide operational bandwidth capability.INDEX TERMS All-metal antenna, Slot-Connected Cavity, 3D Vivaldi antenna, CNC manufacture, additive manufacture, wireless power transfer (WPT), wireless power telemetry.
