Title: Design of a Shape Optimized Printed-circuit Beamformer
This work presents the experimental realization of a printed-circuit beamformer designed using shape optimization. Shape optimization of the printed-circuit beamformer is enabled through the use of a circuit network solver that utilizes reduced-order models of printed-circuit unit cells to rapidly evaluate device responses, and the adjoint variable method to evaluate gradients. The designed beamformer is patterned on a microwave substrate and interfaces with a 3-D printed tapered aperture antenna. It produces nine orthogonal beams and has isolated input ports that are impedance matched. Experimental results for the performance of the 3-D printed antenna and the beamformer will be presented at the conference.  more » « less

    We introduce a mutual information based optimization for a two-port multiple-input single-output (MISO) antenna system. We develop a complete circuit-level analysis of a compact MISO system in the wideband regime. We design a physically realizable antenna array and study the impact of mutual coupling on the spectral efficiency. Then, we maximize the system's mutual information by optimizing the beamformer under two different power constraints, namely the total dissipated power and the available power of the amplifiers. By varying the inter-element antenna spacing, we present results for the achievable spectral efficiency under different power amplifier constraints.

    This work presents the design, analysis, and experimental validation of a novel chip-based 3-D printed ultra-high frequency (UHF) radio frequency identification (RFID) sensor designed for leaf moisture detection for smart farming applications. The presented sensor is designed to operate at a frequency of 915 MHz and utilizes an integrated circuit (IC) chip having a specified impedance of 18.06−j164 Ω at 915 MHz. The proposed sensor is fabricated by the state-of-the-art Nano Dimension DragonFly IV 3-D printer. The 3-D printer uses both dielectric and conductive inks in a single printer for producing additive manufactured electronics (AME). The performance of the sensor is validated by experiments conducted on Valley Oak, Japanese tree lilac, and Crabapple leaf samples. The sensor’s functionality is based on its ability to detect variations in the dielectric properties of leaves, which are caused by changes in moisture content. This is achieved by analyzing the radio frequency (RF) backscattered signal, measured in terms of the received signal strength indicator (RSSI) levels, using a standard RFID reader. Experimental results demonstrate a consistent linear relationship between RSSI levels and leaf moisture content that is used to obtain a calibration curve that can accurately determine unknown moisture levels. By integrating advanced fabrication techniques with reliable RF sensing mechanisms, this work offers a sustainable, and scalable solution for monitoring plant health and optimizing agricultural productivity.

    Laser enhanced direct print additive manufacturing (LE-DPAM) technology has recently been demonstrated to achieve success in packaging of antennas with phase shifters to realize passive phased antenna arrays (PAAs). Utilizing LE-DPAM for PAAs operating in mm-wave bands brings out new challenges that need to be addressed. These challenges are associated with smaller antenna and feature sizes needed for mm-wave band operation, necessity of active circuits for amplification, and number of pads, pad size and pad locations of mm-wave beamformer IC packages. This paper presents our initial progress in scaling LE-DPAM based packaging of PAAs into the mm-wave band operation through consideration and demonstration of discrete components (i.e. antenna array elements and beamformer ICs) that form the PAA structure. Specifically, a stand-alone, passive, 2×2 LE-DPAM based 26 GHz antenna subarray is investigated for its performance. In addition, a 24.5 GHz – 27 GHz beamformer IC is packaged in a stand-alone test article using LE-DPAM and investigated for its mm-wave performance and thermal aspects.

    This paper demonstrates the design and implementation of two dual-polarized ultra-wideband antennas for radar ice sounding. The first antenna operates at UHF (600– 900 MHz). The second antenna operates at VHF (140–215 MHz). Each antenna element is composed of two orthogonal octagon-shaped dipoles, two inter-locked printed circuit baluns and an impedance matching network for each polarization. We built and tested one prototype antenna for each band and showed a VSWR of less than 2:1 at both polarizations over a fractional bandwidth exceeding 40 %. Our antennas display cross-polarization isolation larger than 30 dB, an E-plane 3-dB beamwidth of 69 degrees, and a gain of at least 4 dBi with a variation of ± 1 dB across the bandwidth. We demonstrate peak power handling capabilities of 400-W and 1000-W for the UHF and VHF bands, respectively. Our design flow allows for straightforward adjustment of the antenna dimensions to meet other bandwidth constraints.
