Low‐cost, compact millimeter‐wave antenna‐in‐package for short‐range wireless communications

Abstract

This article presents a low-cost, compact millimeter-wave antenna-in-package (AiP) for short-range wireless communications. The antenna is based on a Yagi-Uda antenna for high gain and end-fire radiation and is implemented on a single dielectric layer using a truncated printed circuit board. Integrated with a CMOS transceiver chip, the AiP provides a low-cost, compact, and robust design. The antenna comprises a microstrip-to-coplanar strip line transition, driver, reflector, and director. The fabricated antenna and AiP have dimensions of 6 mm 3 5.5 mm 3 0.13 mm and 6 mm 3 7.2 mm 3 0.13 mm, respectively. The antenna has measured beamwidths of 688 (E-plane) and 1058 (Hplane) and a gain of 6.6 dBi at 60 GHz, while the fabricated AiP achieved a 10.7-Gb/s wireless data transmission rate over 5 cm at a biterror rate of less than 10 212 .

Co‐design of Sub‐6 GHz and mm‐wave array antennas with metal frame for 5G mobile terminals

“…Phased arrays are adopted in mm‐wave band to provide high gain, where wide beam steering range is needed 2 . In the past decade, numerous antenna designs have been proposed for mobile terminals that can achieve MIMO function in Sub‐6 GHz band 3–7 or beam steering function in mm‐wave band 8–11 …”

“…2 In the past decade, numerous antenna designs have been proposed for mobile terminals that can achieve MIMO function in Sub-6 GHz band [3][4][5][6][7] or beam steering function in mm-wave band. [8][9][10][11] The antenna space in mobile terminals is strictly limited. It will be attractive if Sub-6 GHz antenna and mm-wave antenna can share the same radiating aperture.…”

Constant Envelope Modulation Techniques for Limited Power Millimeter Wave Links

“…Recent technological developments have made extremely high frequencies (EHF) a candidate for wireless applications, such as for the fifth generation (5G) of cellular communications (for which bands in the 24.25-29.5 GHz and 37-43.5 GHz are already allocated [1]), satellite communications [2,3], high resolution radars [4,5], and remote sensing [6,7]. The realization of wireless communications in the millimeter wavelength systems is becoming commercial, compact, and less expensive [8,9].…”

The realization of wireless communications in the millimeter wavelength systems is becoming commercial, compact, and less expensive [8,9].However, the fact that the atmospheric medium is not entirely transparent to millimeter waves (MMWs) requires careful considerations regarding the frequency selective absorption and dispersion effects emerging in this band [10]. Moreover, low power transmissions and reduced receiver sensitivities lead to further degradation in the link performances [11].…”
