Summary: This paper proposes a four-branch dipole antenna designed to conform to the wing of an unmanned aerial vehicle. The antenna achieves better impedance matching performance through the use of branches. Additionally, metallic coupled strips are used to address scanning blindness without affecting broadside radiation. The inclusion of metallic strip directors effectively compresses the beamwidth in the vertical plane and increases element gain. A 12-element linear phased array based on the dipole element is designed and simulated, achieving a scanning range of +/- 60 degrees in the horizontal plane with good voltage standing wave ratio. The measured results of the fabricated antenna prototype validate the feasibility of the wing-conformal linear phased array design.

Summary: This article presents a novel low-profile ultra-wideband and wide-scanning array antenna using the transversely connected folded tightly coupled dipoles array (TCF-TCDA). The antenna extends the operational frequency band with tightly coupled folded dipole arms and uses capacitively-loaded metallic walls to mitigate bandwidth-limiting loop mode. A meta-surface-based wide angle impedance matching (MS-WAIM) layer is used to improve beam scanning ability and lower the antenna profile. Experimental results show good agreement between design and measurement, demonstrating the antenna's ultrawide bandwidth, wide scanning range, compact size, and low cost, making it a promising candidate for modern wireless systems.

Summary: This letter reports on a low-profile, wide-scan antenna array operating in the 6-12 GHz band with planar and conformal variants. The design includes capacitively coupled dipoles and an artificial magnetic conductor layer to achieve the desired low profile. Simulation and analysis of both the conformal and planar array configurations show good performance in terms of VSWR, radiation pattern, and realized gain, making it an attractive candidate for wireless devices at C and X-band frequencies.

Summary: This paper presents a shorted trapezoidal substrate integrated waveguide (SIW) antenna with a quasi-hemispherical pattern composed of a 64-element (8 x 8) 2-D planar phased array. The proposed antenna is analyzed and simulated in terms of resonating mode and magnetic current. It is composed of a trapezoidal patch and shorting vias, which enables the magnetic currents to resonate in three different directions. The 64-element (8 x 8) 2-D planar phased array has been implemented and measured, demonstrating a wide scan range in all azimuth directions.

Summary: In this article, a novel irregular phased array composed of subarrays with two isolated elements (SCTIEs) is proposed. The article investigates the reasons for the significant drop in directivity in traditional polyomino-shaped irregular arrays during large-angle scanning. To reduce quantization errors, the proposed array interleaves two elements with an element belonging to another subarray. Additionally, a Subarray Rotation Algorithm based on Monte Carlo algorithm is proposed to solve the complex double-element irregular subarray tiling problem. Through the array tiling generation and excitation coefficients optimization, the SCTIE-shaped irregular arrays achieve better radiation performance compared to conventional domino-shaped arrays, while maintaining stable performance across a broad frequency band and different array scales.
