U-Slot Dual-Band Planar Inverted-F (PIFA) for 5G in Sub-6 Ghz Spectrum Bands

Salonen P., was the one who first proposed the idea of Double band performance of a planar reversed F antenna utilizing a U-shaped slot with a planned use for Wireless LAN at 2.4/5.2 GHz (IEEE 802.11b/a). The lower and upper frequency bands basically depends on and essentially controlled by the measurement of the external and internal plate separately. This design is normally implemented in places where there is a strong limitation in terms of space and also where the design can operate in multipath environment circumstances, something similar to mobile phones and wireless LAN operation environments. The performance of this and the related minimized designs are normally poor in contrast to the bigger and customary designs. The radiation pattern example and method of operation are not very much characterized, particularly for the upper design band, where the radiation pattern will in general stray from omnidirectional and changes quickly with frequency. In the geometry utilized here, the short is set unevenly as an afterthought confronting the upper finish of the U-shaped opening. In any case, there are various conceivable feed/short setups.

Dual Band Antenna

This paper presents the antenna designed with radiating structure of 3.5 for dual band applications. This antenna is designed and simulated by using CST Studio Suite software at 2.4 GHz and 5.2 GHz based on standard IEEE 802.11a (5.15 GHz-5.35 GHz) and IEEE 802.11b (2.4 GHz-2.48 GHz) frequency bands. The radiating structure 5 and 3 are designed to radiated at frequency 2.4 GHz and 5.2 GHz respectively. Then, both structures are combined to achieve dual band resonant frequencies. The techniques that have been used to achieve dual band resonant are by designing the 3.5 shaped by using planar and coplanar waveguide (CPW) structures. There are three designs of dual band antenna which are Design A, Design B and Design C. The optimum return loss for 2.4 GHz and 5.2 GHz frequency response are -16.44 dB and -18.78 dB respectively achieved by Design C. The changes on the position of radiating structure 3 will effects the frequency response, return loss and gain of the antenna.

Directional Radiation

Abstract In the proposed research paper, a novel compact, ultra-wideband electronically switchable dual-band omnidirectional to directional radiation pattern microstrip planar printed rectangular monopole antenna (PRMA) has been presented. The proposed antenna system has an optimum size of 0.26 λ0 × 0.28 λ0. A combination of radiators, reflectors, and two symmetrical grounds does place on the same layer of the rectangular microstrip PRMA. The frequency agility and the radiation pattern from omnidirectional to directional are achieved using two SMD PIN diodes (SMP1340-04LF). The directional radiation patterns with 180° phase shifts are achieved at the C-band frequency spectrum. The parametric study of the proposed antenna system was performed for different design parameters, and the antenna characteristics were analyzed. An antenna prototype is fabricated using the printed circuit board etching method by using RMI UV laser etching and cutting tools. The measurements of the proposed antenna are conducted in an anechoic chamber to validate the simulations. There are three states of operations due to two SMD PIN diodes being used in switching circuits. In state-I, the proposed antenna radiates at 6.185 GHz (5.275–6.6 75 GHz) in the Ф = 270° direction with a gain of 2.1 dBi, whereas in state-II, it radiates at 5.715 GHz (5.05–6.8 GHz) in the Ф = 90° direction with a gain of 2.1 dBi. In state-III, the antenna exhibits the X-band frequency with center frequency at 9.93 GHz (8.845–10.49 GHz), and the omnidirectional pattern offers a gain of 4.1 dBi. The features of the proposed antenna are suitable for high-speed wireless sensor network communication in industries such as chemical reactors in oil and gas and pharmaceuticals. It is also well suited for IoT and 5G-sub-6-GHz applications.

Global Positioning

A novel high-performance circularly polarized (CP) antenna is proposed in this paper. Two separate antennas featuring the global positioning system (GPS) dual-band operation (1.575 GHz and 1.227 GHz for L1 band and L2 band, resp.) are integrated with good isolation. To enhance the gain at low angle, a new structure of patch and two parasitic metal elements are introduced. With the optimized design, good axial ratio and near-hemispherical radiation pattern are obtained.
