“…Finally, we considered the FR-4 PCB-based AiP to have the lowest cost based on having the cheapest material cost for the FR-4 epoxies, as described in [19] and [26], even with the use of an HDI process. Otherwise, in the bandwidth comparisons, the previous antennas using additional techniques such as ME dipoles [9] and stack patches [15], [21] show wider bandwidth characteristics compared to our proposed antenna. Unlike our proposed AiP, these antennas with additional techniques have more than two resonance frequencies, resulting in a widening of their bandwidths.…”

“…In addition, the proposed AiP supports dual-polarization with marked performance in terms of both the port-to-port isolation and the XPI. At the same time, the proposed design offers excellent gain performance as compared to the other AiPs described in [9], [21] with the same array size of 4 × 4, while using a highly cost-effective material laminated stack-up and the standard PCB process.…”

“…In this section, the antenna array design is introduced in detail, and its performances are evaluated. In order to verify and to compare the antenna in an array configuration to precedent AiP researches [9], [21], we chose the array size as 4 × 4. In addition, dummies were employed for maintaining uniformity of the radiation patterns of the active elements located on the outer edges, as described in [14].…”

“…Several works have been conducted to design dualpolarized AiPs for mmWave communications. The dualpolarized AiPs implemented using low-temperature co-fired ceramic (LTCC) technology were reported in the literatures [7]- [9]. They provide superior performance in terms of efficiency, loss, and gain and offer a high degree of integration with the aid of the LTCC process [10].…”

A Cost-Effective Antenna-in-Package Design With a 4 × 4 Dual-Polarized High Isolation Patch Array for 5G mmWave Applications

A cost-effective antenna-in-package design based on a 4 × 4 dual-polarized high isolation patch array for 5G mmWave applications is proposed in this paper. To obtain a cost-effective design, we devised a four-layer metal stack-up structure with dielectric materials consisting of one TLY-5 polytetrafluoroethylene (PTFE) and two FR-4 epoxies. The devised stack-up exhibits a simple and compact geometry due to the small number of layers, which allows the design to be manufactured using a low-priced standard printed-circuit-board process. Additionally, the employed material combination in the stack-up design possesses a high-end PTFE only in the region with the antenna radiators, which enables good antenna radiation performance at an affordable price. In addition, to design a high-isolation patch array for dual-polarized applications using the low-layer stack-up structure, we employed capacitive probes, defected ground structures, and the rotated-fed method in the proposed array design. With these techniques, the designed array exhibited excellent performance with respect to both port-to-port isolation and crosspolarization isolation. The mechanism of improvement in port-to-port isolation was clearly described using the established equivalent circuit model of the proposed structure. As a result, the fabricated antenna-inpackage has the reflection coefficients of less than -10 dB in the targeted frequency range of 26.5-29.5 GHz and has a peak gain of 17.37 dBi at 28 GHz. The measured port-to-port isolations and crosspolarization isolations are higher than 22.63 and 30 dB in the targeted frequency band, respectively.INDEX TERMS 5G mm-Wave, antenna in package (AiP), capacitive probe, defected ground structure (DGS), dual-polarized patch antennas

“…However, the abovementioned antennas have only one linear polarisation. Recently, several kinds of dual-polarised antennas have been developed, such as aperture-coupled antennas [11,12], cavity-backed slot antennas [13], ME dipoles [14], laminated resonator antenna [15], and stacked patch antennas [16]. Nevertheless, the bandwidths of these dual-polarised antennas are all less than 30.0%.…”

Multi‐resonance dual‐polarised symmetrically cross‐slotted square patch antenna for 5G millimetre‐wave broadband applications

A dual‐polarised symmetrically cross‐slotted square patch (SCSSP) antenna with multimode resonance is proposed for 5G millimetre‐wave broadband applications. A symmetrical cross‐slot is etched on the square patch surface to change the original E‐field distribution where a whole square patch is cut into four disconnected equal parts. For both polarisations, this etching also tunes the resonance frequencies of the two modes to be sufficiently close to each other. Therefore, the antenna can realize good impedance performance within the wide designated bandwidth. Dual‐polarised radiation of the SCSSP is vertically excited by three bow‐tie‐shaped slots and fed by two orthogonal substrate integrated coaxial lines. Simulated and measured results show that the fabricated prototype achieves a broad overlapped impedance bandwidth of 50.0% (24–40 GHz), isolation higher than 30 dB between the two input ports, stable radiation pattern, and low cross‐polarisation over the operating band. Moreover, the proposed SCSSP antenna with compact size, planar shape, and simple vertical feeding is very well‐suited for two‐dimensional array design.
