TL;DR: In this article, the integration of a low-profile antenna array with a multicrystalline silicon solar cell capable of powering a low power wireless sensor at 2.45 GHz is reported.
Abstract: The integration of a low-profile antenna array with a multicrystalline silicon solar cell capable of powering a low-power wireless sensor at 2.45 GHz is reported. Lattice bus bars on the cell are exploited to minimize antenna shadows from low-profile antennas and transmission lines for a higher output power. The dual inverted-F array improves gain, and beam switching enables the array to sweep a wider coverage angle with larger beamwidths compared to other solar integrated antennas.

TL;DR: In this article, a method for the calculation and accurate prediction of the noise coupling in a phased antenna array is introduced, which is shown to be related to the scan reflection coefficient, a measurable antenna parameter.
Abstract: A method for the calculation and accurate prediction of the noise coupling in a phased antenna array is introduced. The noise coupling is shown to be related to the scan reflection coefficient, a measurable antenna parameter. This leads to a method of calculating the noise coupling of the array using scattering parameters, which can then be used in design of a receive-mode phased array. A 49-element dipole array at 1 GHz using HPMGA-82563 LNAs is used as an example to calculate the parameters of interest for a low-noise phased array design.

TL;DR: In this article, the authors proposed a conformai, thin antenna that would neither, disturb the aerodynamic flow, nor would it protrude inwardly to disrupt the mechanical structure.
Abstract: High velocity aircraft, missiles, and rockets require conformai, thin antennas. Ideally, an antenna "paper thin" would best suit the aerodynamic and mechanical engineer. This antenna would neither, disturb the aerodynamic flow, nor would it protrude inwardly to disrupt the mechanical structure.

TL;DR: In this article, an array of multisegment dielectric resonator antennas fed by a multilayer microstrip branch-line network is presented, achieving a gain peak of 15.4 dBi with a 3 dB gain bandwidth of 17% and an efficiency of 66%.
Abstract: A novel antenna is presented consisting of an array of multisegment dielectric resonator antennas fed by a multilayer microstrip branch-line network. A prototype array has been designed and fabricated at X-band and its measured performance includes a gain peak of 15.4 dBi with a 3 dB gain bandwidth of 17% and an efficiency of 66%. This array can be used as a medium gain, wideband antenna, or can form a subarray in a large low-profile structure for high gain applications.

TL;DR: In this article, an array of four uniform half-width microstrip leaky-wave antennas (MLWAs) was designed and tested to obtain maximum radiation in the boresight direction.
Abstract: An array of four uniform half-width microstrip leaky-wave antennas (MLWAs) was designed and tested to obtain maximum radiation in the boresight direction. To achieve this, uniform MLWAs are placed at 90 $ ^\circ $ and fed by a single probe at the center. Four beams from four individual branches combine to form the resultant directive beam. The measured matched bandwidth of the array is 300 MHz (3.8–4.1 GHz). Its beam toward boresight occurs over a relatively wide 6.4% (3.8–4.05 GHz) band. The peak measured boresight gain of the array is 10.1 dBi, and its variation within the 250-MHz boresight radiation band is only 1.7 dB.
