“…DUAL-band antennas for circular polarisation (CP) are preferred because the antennas can be used in the multiband applications simultaneously, and circularly polarised waves can reduce polarisation losses between the transmitting and receiving antennas. In dual-band printed antenna for CP, there are two types of polarisation senses, a single sense [1][2][3][4][5] and dual-sense [6][7][8][9][10][11][12][13]. The dual-sense antennas are useful for applications where dual-sense reception of both left-hand circular polarisation (LHCP) and right-hand circular polarisation (RHCP) signals are required [12].…”

A compact printed hybrid‐mode antenna for dual‐band dual‐sense circular polarisation (CP) has been proposed. To achieve dual‐band dual‐sense CP, a hybrid mode produced by an L‐shaped element and a loop element is used. In the lower frequency band, the left‐handed CP is radiated by a vertical electric field from the L‐shaped element and a horizontal electric field from the loop element. In the higher frequency band, the right‐handed CP is radiated by a horizontal electric field from the L‐shaped element and a vertical electric field from the loop element. Both the L‐shaped and the loop elements produce resonances in the lower and higher frequency bands. The operational principle for dual‐band dual‐sense CP is clarified using the simulated orthogonal components of the electric fields and the simulated electric current distributions. Parametric studies are discussed in the design procedure. The simulated and measured input reflection coefficient, axial ratio, absolute gain, and radiation pattern are presented. The measured bandwidths of −10dB‐input reflection coefficient with a 3dB‐axial ratio are 2.37–2.55 GHz (7.32%) in the lower frequency band and 3.38–3.70 GHz (9.04%) in the higher frequency band. The antenna size is 0.0741λ2.452 and 0.151λ3.52 (λ f is a wavelength at f GHz).

“…In the literature, different shapes of the single-band and multi-band monopole antennas have been developed, such as H-shaped [11], circular-shaped [12], U-shaped open stub [13], M-shaped open stub [14], L-shape with coupled branch strip [9], L-shaped stub folded into U-shaped [4], D-shaped [15], U-shaped with rectangular patch inside [16], square spiral loop [17], tapered rectangular patch antenna [5], and symmetric bow-tie circular patch antenna [18]. Dual-band or multi-band operations can be obtained by etching some slots either in the radiating elements [3,[18][19][20][21][22], in the ground plane of the antennas [23][24][25][26], or both [9,27,28]. A square microstrip patch etched with four symmetrical slots [29][30][31][32][33] has been proposed for nondegenerate dual-mode filter applications.…”

This paper presents novel low-cost single- and dual-band microstrip patch antennas. The proposed antennas are realized on a square microstrip patch etched symmetrically with four slots. The antenna is designed to have low cost and reduced size to use in Internet of things (IoT) applications. The antennas provide a reconfigurable architecture that allows operation in different wireless communication bands. The proposed structure can be adjusted to operate either in single band or in dual-band operation. Two prototypes are implemented and evaluated. The first structure works at a single resonance frequency (f1 = 2.4 GHz); however, the second configuration works at two resonance frequencies (f1 = 2.4 GHz and f2 = 2.8 GHz) within the same size. These antennas use a low-cost FR-4 dielectric substrate. The 2.4 GHz is allotted for the industrial, scientific, and medical (ISM) band, and the 2.8 GHz is allocated to verify the concept and can be adjusted to meet the user’s requirements. The measurement of the fabricated antennas closely matches the simulated results.

SummaryThis article presents a highly compact printed radiator for direct broadcast satellite (DBS) systems that exhibits good gain and left‐handed circular polarization. The inferred pattern is accomplished by etching two isosceles triangles, one from each of the four corners of a square. From the center of the newly acquired structure, a circular geometric design is made up of 16 isosceles‐scaled triangles has been etched. This arrangement induces resonance in the antenna, aligning it with the desired frequency. The proposed antenna is designed using PCB laminated Rogger 5880 material and simulated in a CST EM simulator. The antenna under consideration exhibits a significant size reduction, achieving a miniaturization ratio of 21.03%. The LHCP antenna resonated at 12.61 GHz and offered a decent LHCP gain of 7.95 dBic. It gives 0.56 GHz CP bandwidth, which covers the DBS service band entirely. It also provides 96.43% radiation efficiency and 44.27 dB/m correction factor, respectively. All the measured findings of the prototype agree with its simulated one.
