Designing an ultra-wideband array antenna for fifth generation (5G) is challenging for the
antenna designing community because of the highly fragmented electromagnetic spectrum …

To eliminate the grating lobes of subarrayed phased arrays, the state-of-the-art methods
mainly use subarrays of various shapes to make up an irregular subarray tiling configuration …

A novel and effective method for the design of maximum directivity irregular phased arrays is
proposed in this article. By decomposing the radiation pattern of irregular arrays (IAs) into …

The design and performance of a thinned singly polarized all-metal Vivaldi phased array are
presented. A genetic algorithm (GA)-based optimization is employed to demonstrate the …

A high-directivity optimization technique for irregular arrays combined with maximum
entropy model is presented. First, the major cause of the reduction in directivities of irregular …

An irregular tiled array technique is proposed for the application of massive MIMO systems,
where the uniformly spaced antenna array elements are irregularly divided into subarrays …

An irregular tiled array technique with the maximization of beam collection efficiency (BCE)
for microwave wireless power transmission (WPT) is addressed in this paper, where the …

Phased array antenna (PAA) scanning faces challenges from element spacing requirements
to prevent grating lobes, conflicting with the trend towards higher frequencies and cost …

The phased array technologies usually suffer from high fabrication costs, high-density
integration, and heat dissipation, which limit their use, particularly for large-scale phased …

A thinned irregular tiled array synthesis approach is proposed for 5G base station array
design. To fit the needs of multiusers, different sizes of vertical tiles with thinned elements ae …
