Title: Grating Lobe Mitigation in Scanning Planar Phased Array Antennas
This paper presents the grating lobe reduction in a planar phased array antenna with a rectangular lattice and large element spacing in the order of one wavelength for scan angles up to ±45°. A dual-mode circular microstrip patch antenna is considered as the constitutive element of the phased array, in which two different transverse magnetic modes are exploited simultaneously. The numerical analysis shows that the achieved grating lobe reduction is well below 25 dB for scan angles up to ±45° with large element spacing in the order of one wavelength.  more » « less

    Abstract|The experimental validation of reduced grating lobes in a seven-element, hexagonal, scanning phased array antenna with the one-wavelength element spacing is presented. The base element of the array is a single-layer, dual-mode antenna with self-scanning and nulling properties. For the selected scan angle of ¡30±, the required microstrip transmission line based feeding network, consisting of ring hybrids, power splitters, and branchline couplers, are designed and developed. A prototype of the complete array and feeding network was fabricated and successfully tested to show the e®ectiveness of the grating lobe reduction method using the dual-mode antenna elements in scanning phased array antennas with the one-wavelength element spacing.

    Abstract The characterization of antenna radiation patterns in millimeter‐wave (mmW) bands can be particularly challenging. Due to a small wavelength, minute misplacement of the probe antenna in the order of few millimeters can generate substantial errors in the measured pattern. A highly precise measurement system that incorporates a 6‐axis compact robotic arm is implemented to overcome this challenge. System testing shows a positional accuracy and repeatability of approximately 20 μm or 0.004λ at 60 GHz. After implementation, programming, and testing, the system is used to measure gain patterns on three different mmW antennas. The radiation pattern of a 50–75 GHz standard gain horn antenna demonstrated the accurate measurement at the far‐field using the robotically controlled system. Furthermore, the characterization of the center element pattern of a 60 GHz phased array has shown that the measurements with this system are repeatable and suitable for arrays as well. Additionally, we performed near‐field measurements by successfully characterizing a 40–60 GHz horn antenna with a planar scan.

    An electromagnetic cloaking approach is employed with the intention to curb the destructive effects of mutual interference for rectangular and circularly shaped patch antennas situated in a tight spacing. Primarily, we show that by coating the top surface of each patch with an appropriately designed metasurface, the mutual coupling is considerably reduced between the antennas. Furthermore, the cloak construct is extended to a tightly spaced, interleaved linear patch antenna array configuration and it is shown that the coated metasurfaces successfully enhance the performance of each array in terms of their matching characteristics, total efficiencies and far-field realized gain patterns for a broad range of beam-scan angles. For rectangular patches, the cloaked Array I and II achieve corresponding peak total efficiencies of 93% and 90%, in contrast to the total efficiencies of 57% and 21% for uncloaked Array I and II, respectively, at their operating frequencies. Moreover, cloaked rectangular Array I and II exhibit main lobe gains of 13.2 dB and 13.8 dB, whereas uncloaked Array I and II only accomplish main lobe gains of 10 dB and 5.5 dB, respectively. Likewise, for the cloaked circular patches, corresponding total efficiencies of 91% and 89% are recorded for Array I and II, at their operating frequencies (uncloaked Array I and II show peak efficiencies of 71% and 55%, respectively). The main lobe gain for each cloaked circular patch array is approximately 14.2 dB, whereas the uncloaked Array I and II only achieve maximum gains of 10.5 dB and 7.5 dB, respectively.

    This paper presents a compact phased-array antenna for efficient and high-gain millimeter-wave-based 3D beam steering applications. The proposed antenna array consists of 2 × 2 unit cells and each unit cell is a sub-array comprising of 2 × 2 patch elements connected to microstrip lines that are co-fed by a single coaxial cable. Two 45° phase shifting lines are incorporated in each sub-array to facilitate the wide beamsteering range. The dimensions of the proposed phased array antenna are 24 × 24 × 0.324 mm 3 . Simulation results show that the proposed phased-array antenna has a resonating frequency at 58.4 GHz with an operational bandwidth from 50.1 GHz to 77.5 GHz along with a high gain of 26.8 dBi. The array exhibits a maximum beam steering range of 105° in the elevation plane and 195° in the azimuth plane with a gain variation less than 0.9 dBi.

    This paper presents a flexible 10 × 10 phased-array antenna for efficient and high-gain 3D beam steering applications. The proposed antenna array consists of 25 quadrants of 2 × 2 unit cells, wherein each 2 × 2 unit cell is coaxially fed. The 45° phase shifting lines are incorporated in the feeding paths to facilitate the wide beamsteering range. The dimensions of the proposed phased array antenna (PAA) are 90 × 90 × 0.324 mm 3 . Simulation results show that the proposed phased-array antenna has a resonating frequency at 24 GHz with an operational bandwidth from 23.64 GHz to 24.31 GHz along with a high gain of 29.4 dBi. The array exhibits a maximum beam steering range of 149.8° in the θ axis and 120° in the ϕ axis with a gain variation less than 0.9 dBi. The proposed flexible PAA is suitable for its placement on curved surfaces of autonomous vehicles such as UAVs(Unmanned aerial vehicles).
