“…We used ANSYS HFSS software for designing the antenna corresponding microstrip feedline of 50-ohm impedance power source and for validation of antenna results, we also used CST STUDIO SUITE to design a single antenna. The basic governing equations for the microstrip patch width and length can be expressed as [1,[20][21][22][23][24] Patch width…”

This study designs a microstrip patch antenna with an inverted T-type notch in the partial ground to detect tumor cells inside the human breast. The size of the current antenna is small enough (18 mm × 21 mm × 1.6 mm) to distribute around the breast phantom. The operating frequency has been observed from 6-14 GHz with a minimum return loss of −61.18 dB and the maximum gain of current proposed antenna is 5.8 dBi which is flexible with respect to the size of antenna. After the distribution of eight antennas around the breast phantom, the return loss curves were observed in the presence and absence of tumor cells inside the breast phantom, and these observations show a sharp difference between the presence and absence of tumor cells. The simulated results show that this proposed antenna is suitable for early detection of cancerous cells inside the breast.

“…Operating at 12 GHz, it achieves high efficiency, impressive directivity, and a favorable axial ratio, rivaling traditional dish antennas in receiving power and channel-to-noise ratio while boasting a smaller form factor [2]. A separate venture delves into the realm of compact monopole wideband antennas with defected ground planes, presenting a versatile solution that harnesses multiband performance alongside stable radiation patterns [12]. Detailed in a separate paper are helical antennas operating at 10 GHz, complete with theoretical design structures, formulae for essential parameters (e.g., directivity, beamwidth, impedance, and axial ratio), and profiles of simulated gain and directivity.…”

A helix antenna serves as an electromagnetic emitter that transmits signals in the shape of a coiled thread. It possesses two primary operational modes: normal and axial. In the axial mode, radiation peaks along the helix's axis, creating a near-circular concentration of electromagnetic waves. This paper delves into the intricacies of designing a spiral antenna optimized for operation at a 3 GHz reverberative frequency. It exhibits indirect polarization and is ideally suited for wireless communications, facilitating the transmission and reception of VHF waves, especially for ionospheric propagation. The versatility of this antenna extends to various applications, including radio astronomy, space telemetry, satellites, and space-based communication systems. The proposed antenna design showcases a directional radiation pattern with a notable gain of 13.8 dB. Future research will explore its adaptability for deployment in aquatic environments, expanding its utility in scenarios that demand reliable wireless connectivity beneath the surface. This innovation holds great promise for enhancing communication capabilities across a range of fields and environments.

“…The sectoral MSA designs reported in [10,11] require additional shorting post, slot, or stub, and yet offer smaller BW. Although the designs reported in [12][13][14][15] offer substantially higher BW, the reported configurations are complex in design, and they do not provide explanations for the antenna functioning in terms of the patch resonant modes. In comparison, the proposed designs are simpler in implementation, since it just requires a modified ground plane employing proximity feeding.…”

“…However, these techniques are complex in design, and they require a thicker substrate to achieve optimum BW. Alternatively, defected ground plane structures (DGSs) have been used to increase the MSA BW [11][12][13][14][15]. Although a BW of more than 70% has been achieved here, the effects of modifications in the ground plane profile on the patch resonant modes and their impedances that yield wider BW have not been clearly explained.…”

Wideband designs of proximity fed regular shape microstrip antennas using bow-tie and H-shape ground plane profiles are proposed in the 1000 MHz frequency range. The modified ground plane alters the quality factor of the patch cavity which enhances the impedance bandwidth. In terms of the results obtained for the bandwidth and gain together, circular and square patches backed by bow-tie shape ground plane, followed by circular patch backed by H-shape ground plane yield optimum results. For substrate thickness of 0.097λ g , against the conventional ground plane, bow-tie shape gives 12% and 24% bandwidth increment for the circular and square patches, respectively, and H-shape ground plane yields bandwidth increment by 17% in the circular patch. All these wideband designs offer a peak gain around 6 dBi with a broadside radiation pattern. Further, a modified ground plane profile helps in optimizing the proximity fed antennas on lower substrate thicknesses. Amongst all the configurations, for ∼ 0.03λ g reduction in the substrate thickness, square microstrip antenna using bow-tie shape ground plane yields 19% increase in the impedance bandwidth against the equivalent thicker substrate design with a peak broadside gain of above 6 dBi. Thus, the proposed modified ground plane antennas yield bandwidth improvement but for a smaller substrate thickness.
