“…Existing efforts to create dual‐band resonance, predicated on slot‐loaded patch technique is reported in 12,13 Though popular techniques (Orthogonal mode dual frequency patch antenna 14,15 multi‐patch dual frequency patch antenna 16,17 and reactively loaded dual frequency patch antennas (microstrip, 18 coaxial 19‐22 spur‐line, 22 pins, 23 capacitor, 24 slots, 25 slots and pin 26 )) for realizing dual band are not new, our focus however, is to uniquely overlap the dual resonances by gradually and consistently stretch the circular center‐embed slot, to a larger surface area, that in turn, bring the TM 11 mode close to TM 100 mode. This is to create a wideband and remain conformal to the target pipe.…”

s A rectangular patch antenna design with fundamental TM100 mode for on‐metal applications is presented. The patch is excited by an inset‐fed microstrip feedline and optimized for better performance by varying the inset‐fed parameters. The patch is then loaded with a circular slot of radius Ry at its center to create additional resonance at TM11 mode. The radius Ry is varied to elongate the circular slot into biconcave shape, to increase its electrical length. Thus, manipulating TM11 mode with respect to TM100 mode to achieve wideband by combining the two resonances using overlap technique. Equations of the resonance of the circular slot is stated and so is the surface area of the biconcave. The resulting antenna is etched on a 130 μm‐thick RO3003 microwave laminate and stamped on a metallic pipe cladding using the pipe as the metallic ground. The realized bandwidth is enhanced by 13% with reasonable achieved directivity. The simulated and measured results agreed reasonably with marginal discrepancy.

“…This patch plays a crucial role in radar systems, satellite communications, military, and airborne communications and remote sensing applications. In general, the patches are fed by different techniques including coaxial fed, aperture coupling [5], microstrip line feed [6], the inset fed, proximity coupling [7], L feed [8] each having different advantages and its limitations. Recently graphene are also used to enhance antenna capabilities [9].…”

The paper presents a novel dual-band patch working at GSM band and S-band. The patch encompasses a rectangular radiator coupled with a parasitic patch in the coplanar region and a split ring resonator in the ground region. The patch is analyzed numerically and is synthesized using the HFSS simulator. Finally, the performance characteristics of the model are measured and are compared with numerical and simulated results. The patch gives two different bands at 950MHz and 2.3GHz and gives -10dB impedance bandwidth in the lower band from 950MHz -1GHz and higher band from 2.275GHz – 2.325GHz. The patch also accomplishes a gain of 4.74dBi in the effective band 1 and 4.02 dBi in the operating band 2.

“…They can be designed using different types of low losses materials, for example_fiberglass, and coated using PTFE-for indoor and outdoor environments [1], However, the main challenge for designing radome is avoiding antenna degradation in terms of attenuation, scattering and depolarization. Furthermore, scattered radiation from the use of radomes may degrade antenna performance in terms of antenna directivity via the enhancement of side lobes [2], The main disadvantages of the microstrip patch antenna are narrower band and low gain [3], Due to these factors, many researches have investigated methods to improve the bandwidth and antenna gain by modifying the ground plane orradiating patch [4][5].…”

This paper present the design of a circular patch microstrip antenna with enhancement in terms of bandwidth and gain using a dielectric double negative (DNG) split ring metamaterial radome. This radome is positioned on top of the CP antenna operating from 5.2 GHz to 6.4 GHz. The metamaterial radome comprises of two alternate split rings of negative permittivity, permeability and refractive index. The circular microstrip antenna bandwidth of 430 MHz has been realized by the presence of DNG metamaterial radome compared to 220 MHz without the radome. The gain has been increased as well from 1.84 dBi to 3.87 dBi.
