“…As another example of printed square slot antenna fed by a CPW is presented in figure 13 [100,101]. In this antenna the 3 dB AR band is enhanced by extending the feedline leftward along the X-direction and upward along the Y-direction to form a halberd-shaped structure.…”

“…In this antenna the 3 dB AR band is enhanced by extending the feedline leftward along the X-direction and upward along the Y-direction to form a halberd-shaped structure. The impedance band is improved by implanting within the slot a grounded asymmetric inverted-T strip [101]. The position of the CP band can be controlled by varying the length and width of halberd-shaped feedline.…”

Circular polarized (CP) antennas are well suited for long-distance transmission attainment. In order to be adaptable for beyond 5G communication, a detailed and systematic investigation of their important conventional features is required for expected enhancements. The existing designs employing millimeter wave, microwave, and ultra-wideband (UWB) frequencies form the elementary platform for future studies. The 3.4-3.8 GHz frequency band has been identified

“…Several designs based on a single port and slot structure have been developed for Global Positioning (GPS) applications. In [6], a CPW-fed slot antenna was designed with a square slot shape fed by a halberd-shaped metal strip. The antenna showed a good axial ratio lower than 3 dB in the 1545-1605 MHz frequency band, but the design required a complex parametric study.…”

This work presents the use of a three-element radiating structure for circularly polarized Low-Power Wide Area Network (LP-WAN) communication with space. The proposed structure has a 72 mm × 72 mm × 12 mm compact size with Right-Handed Circular Polarization (RHCP) and a 120∘ wide beamwidth radiation pattern. Printed on low-cost FR4 Epoxy substrate, a feeding network circuit based on Quasi Lumped Quadrature Coupler (QLQC), it achieves a −0.6 dB insertion loss and a very compact size. The final structure has a 69% total efficiency and a 3.14 dBic realized gain.

“…Along with, use of microstrip-line-fed, planar monopole antennas have also become very promising techniques for multiband applications because of their ease of fabrication, low profile, and admirable transmission characteristics. 1 Among the recently proposed designs for CP antennas, some notable ones are like the ones that used slotted ground with two inverted L-shaped strips along two opposite corners, [2][3][4][5] using CPW fed slots/open slots, 6,7 or by crosspatch loaded square slots. 8 Yet, those designs could offer merely single-or dual-band circular polarizations.…”

Herein a compact triple-band circularly polarized (CP) microstrip patch antenna, loaded with a single annular ring patch with eight symmetrical slots along its periphery and a series of octagonal closed ring resonators (CRRs) on the opposite side of the substrate, is proposed. Evolution process of the antenna geometry reveals that the eight symmetrical slots and the CRRs are responsible for increased impedance bandwidth (IBW), while simulated (high-frequency structure simulator (HFSS) and computer simulation tool) triple CP bands obtained due to the uses of crossshaped slit resonating at 7.5 GHz (152.2 MHz); asymmetric ground plane at 10.2 GHz (161 MHz); and square open-loop at 12.2 GHz (112.5 MHz). Series of parasitic strips improved CP radiation and remove ripple in the radiation pattern. The antenna presented here, is compact, fabricated with an optimized dimension of 35 × 30 × 1.6 mm 3 , on low cost FR-4 substrate with copper cladding. The measured <10-dB IBW ranges from 4.08-5.05 GHz and 5.98 GHz up to 13.6 GHz. Simulated maximum peak gain found to be 4.45 dBi at 13 GHz. The antenna proposed herein is appropriate for wireless applications.
