3B that the average measured in-band return loss and insertion loss of the fabricated Filter are about 13.91 and 2.14 dB, respectively. | C ONCL US I ONA new implementation of the millimeter-wave Filter using GGW technology was presented. The proposed method has the advantages of high performance, low loss, manufacturing flexibility, and compact size. Negative coupling and stacked structure were realized here for the first time in the design of millimeter-wave GGW filter. Finally, a Ka-band filter based on the proposed method was simulated and fabricated to confirm the primary expectations. The simulation and measurement results are in good agreement and exhibit high doublesided selectivity of more than 25 dB/100 MHz. Therefore, a careful comparison between the proposed construction and previous ones demonstrates the unique capability of the proposed structure in terms of the high performance, compactness, and design flexibility. ORCID AbstractIn this paper, a dual-band impedance transformer with filtering integration and DC-block function is proposed for the first time. Excellent frequency selectivity is achieved by the dual-narrowband filtering integration with two pairs of transmission zeros (TZs) at both sides of the dual SUN ET AL.| 233

“…In theory, circular polarization of a patch antenna is realized by exciting two orthogonal components of identical amplitude [1]. Specifically, in [2], a circular monopolar patch antenna with U-slot patch and four slots achieved dual-band (2.45 and 5.8 GHz) CP omnidirectional radiation pattern at the respective gains of 1.37 and 4.37 dBi. In [3], a CP quad-band antenna using metamaterial was proposed.…”

This research proposes a circularly polarized (CP) single-fed omnidirectional dipole antenna operable in 2.45 GHz frequency for the industrial, scientific, and medical (ISM) radio band applications. The proposed antenna consisted of bisectional dipole core, a pair of quarter-wave baluns, and four diagonally adjoined parasitic braces. The bisectional dipole core was utilized to improve the antenna gain and realize omnidirectional radiation pattern, and the quarter-wave baluns were to symmetrize the current on the bisectional core. The four parasitic braces collectively generated circular polarization. In the study, simulations were conducted using CST Microwave Studio and a prototype antenna fabricated. To validate, experiments were carried out, and simulation and experimental results compared. The finding revealed good agreement between the simulation and experimental results. Essentially, in addition to achieving an antenna gain of 2.07 dBic, the proposed CP single-fed omnidirectional antenna is suited to ISM frequency band applications.

This article presents the design and analysis of a dual-band antenna with circular polarization for ISM and WLAN band applications. The proposed antenna operates at two frequencies ranging from 2.1-3.1 GHz and 4.4-7.7 GHz with resonating frequencies at 2.45 GHz industrial, scientific and medical band (ISM) and 5.8 GHz wireless local area network band (WLAN). The antenna is fed by coplanar waveguide feeding (CPW) with an asymmetric ground structure, and the radiating element consists of 24 spokes in the design. The current antenna providing the impedance bandwidths of 38.4% and 49% at two operating bands. The proposed antenna exhibiting circular polarisation with 3 dB axial ratio bandwidth of 150 MHz at 2.33-2.48 GHz and 1600 MHz at 5.14-6.74 GHz. The designed antenna is fabricated on an RT Duroid 5880 substrate with dimensions of 40 × 28 × 0.4 mm 3 . The intension behind the design of this antenna is to use it for wearable applications in conformal nature with low specific absorption rate (SAR). The SAR values observed at two operating frequencies are 1.09 W/Kg and 1.47 W/Kg on hand and 0.946 W/Kg and 1.12 W/Kg on head, respectively. The placement and radiation characteristics analysis is done with Ansys Savant tool, and the subsequent measured results provide good correlation with simulation results.
