“…In order to design a 28 GHz antenna with high front to back ratio, broadside radiators such as patch antennas are avoided as the radiation would be towards the user, when being engaged in data consumption. End-fire antennas such as Vivaldi or tapered slot antenna might be a solution [10][11][12] to solve the back radiation issue, but the integration with the panel of the mobile device is compromised due to its electrically large size, even when being scaled to 28 GHz band. Hence, a polycarbonate based angled dipole integrated with parasitic radiators is proposed as displayed in Fig.…”

“…The ACS (Asymmetric Coplanar Stripline) feeding technique for miniaturization might be incompatible with the underlying electronics which prefer microstrip feeding [8,9]. Even though end-fire antennas such as Vivaldi based antennas have high front to back ratio, they might be unsuitable for panel mounting with mobile devices, as the width of the antennas to achieve high gain would be higher than the required panel height [10][11][12]. It might appear that reconfigurable antennas such as the ones published in [13][14][15] could be used to achieve band switching between 4G and 5G, but the issue with design logic is that realizing the appropriate diodes at 28 GHz would be challenging, also the bias lines and other parasitics would detune the antennas.…”

An extremely close integration of a dual band sub-6 GHz 4G antenna with a 28 GHz 5G antenna is proposed in this article. Firstly, a dual band 4G LTE (Long term Evolution) antenna is designed on an inexpensive substrate. The proposed antenna operates in the 2.5 GHz and 3.5 GHz LTE bands. The antenna has dimensions of 63× 5.6× 0.5 mm 3 , indicating an electrically small design. As the width of the antenna is less than 7 mm, it could be easily mounted on commercial mobile devices. The patterns for both the bands are almost omnidirectional as desired by the low frequency antennas. The proposed antennas do not carry any additional miniaturization or tuning circuitry hence simplifying fabrication process. Secondly, an angled dipole with Yagi topology is proposed, which works in the 28 GHz mmWave 5G band. The angled dipole has dimensions 28.3 × 5.6 × 0.5 mm 3 , which is also electrically compact and has a high front to back ratio. The microwave and millimetre wave antennas are placed orthogonally for minimal mutual coupling. The characteristics of both the antennas are not affected by the presence of the other element. Detailed results are shown in this article.

This paper presents a new miniaturized planar Vivaldi antenna (PVA) design. The proposed antenna structure consists of an aperture tapered profile and cavity stub fed with a simple 50 Ω strip line feeding network. The designed PVA offers versatile advantages, including the miniaturized size and simple design, and exhibited an outstanding performance compared to the latest reported literature. The antenna occupies a minimal space with an electrical size of 0.92λ0 × 0.64λ0 × 0.03λ0. The antenna achieves an excellent relative impedance bandwidth 117.25% at 10 dB return loss, peak realized gain of 10.9 dBi, and an excellent radiation efficiency of 95% at the specific resonances. The antenna’s optimal features, that is, broadband, high gain, and radiation efficiency, are achieved with efficient grooves based approach. Besides, the proposed antenna results are also analyzed in the time domain, which shows the excellent group delay performance <2 ns in the operational band. The proposed antenna exhibited a stable far-ﬁeld radiation pattern in orthogonal planes and strong distribution of current at multiple resonances. Simulation and the measured result show a good agreement. The proposed antenna has achieved optimal performance and is suitable for future wireless communication applications.

Co-design of corner bent Multiple-Input Multiple-Output (MIMO) antennas catering to 4G LTE and mmWave 5G applications is proposed. The 4G LTE MIMO antenna module consists of two element microstrip-fed slot antennas operating from 1.7 to 3 GHz with fractional bandwidth of 55%, which covers LTE1900, LTE2300, and LTE2500 bands. For mmWave 5G MIMO antenna module, two element Vivaldi antennas with wideband operating from 25 to 38 GHz and fractional bandwidth of 41% are proposed. The mmWave 5G microstrip fed Vivaldi MIMO antennas exhibit orthogonal pattern diversity at 28 GHz with 1-dB gain bandwidth of 28%. The single element corner bent co-designed antenna is compact having dimensions of 14 × 51 × 0.254 mm 3. The 4G LTE and mmWave 5G antennas are electrically close to each other by 0.01λ at 1.7 GHz for minimal physical footprint. Co-designed 4G LTE and mmWave MIMO antennas are integrated inside a typical mobile case. Simulated and measured results are presented.
