“…The most common solution found in the state-of-the-art to overcome the bandwidth limitations of the patch antenna is the usage of a stacked patch topology [4,5], as seen in Figure 2. However, such technique usually leads to higher order modes which will degrade radiation pattern stability throughout the band of operation [3].…”

In this paper, we describe the design of a dual polarized packaged patch antenna for 5G communications with improved isolation and bandwidth for K-band. We introduce a differential feeding technique and a heuristic-based design of a matching network applied to a single layer patch antenna with parasitic elements. This approach resulted in broader bandwidth, reduced layer count, improved isolation and radiation pattern stability. The results were validated through finite element method (FEM) and method of moments (MoM) simulations. A peak gain of 5 dBi, isolation above 40 dB and a radiation efficiency of 60% were obtained.

“…The authors of [4] presented an antenna-in-package solution based on LTCC for 28 GHz. A stacked patch topology was used with a stripline-based feeding network that allowed a wide impedance bandwidth of approximately 3.5 GHz to be obtained.…”

“…In [4][5], the metal hole array is used as a wavefront conversion device to enhance the gain. Other techniques to improve the gain are by using the stacked patch configurations [6], increasing resonant frequency of the firstorder mode without changing the size of the patch antenna [7][8], or aperture coupling feed [9]. However, these solutions led to the use of multilayer substrate, resulting in increased complexity and high fabrication cost.…”

In this article, the design of a rectangular patch antenna in the millimeter-wave range is presented. The antenna is placed on a Rogers TC600 substrate with a dielectric constant of 6.15. The antenna resonance is kept around 28 GHz. The proposed work enhances the gain by placing a superstrate at a specific distance from the radiator equal to 0.5 λ, which reflects the electromagnetic wave between the two substrates and, consequently, enhances the gain. As a result, the proposed method enhances the gain by approximately 2.27 dB, which suitable for automotive applications at mm-wave band.

“…The performance improves by embedding the antenna in the package, which reduces the overall interconnect loss [1]. The cost, however, depends on the chosen substrate technology, which can be printed circuit board (PCB) [2], [4]- [6], low-temperature co-fired ceramic (LTCC) substrate [7], glass substrate [8] or organic built-up substrate [1], [9]. Generally, the most cost-efficient approach is to use conventional PCB technology, especially if a small number of dielectric layers are used.…”

A 2x2 integrated antenna array operating at 28 GHz with 4 GHz bandwidth is presented. Conventional PCB technology is used to realize the antenna board, with low fabrication cost by minimizing the number of layers and vias. To overcome limited bandwidth and high mutual coupling, several techniques are used: proximity coupled feedings, slotted patches, and defected ground. The S-matrix and radiation patterns of the standalone antenna prototype are measured before being attached to the IC. The performed S-matrix measurement is a very first of a kind among so far reported integrated arrays at 28 GHz. The measurements confirm a mutual coupling level less than -12 dB. This characterization is used to estimate the performance of the driving power amplifiers. The analysis confirms that the antenna array is well-matched to the IC output, and as a result, the performance of the array does not degrade under beam scanning. The integrated antenna can be used as a tile module to construct larger arrays in arbitrary configurations.
