A miniaturized super-wideband (SWB) monopole antenna is presented in this work. Electrical dimension of the presented antenna is 0.239λ Â 0.239λ Â 0.0147λ, where λ indicates the wavelength corresponding to the lowest operating frequency. Presented antenna displays single À10 dB operating band from 2.75 to 28 GHz with 164% percentage bandwidth and bandwidth ratio of more than 10:1. The proposed SWB antenna exhibits a large bandwidth dimension ratio (BDR) of 2871 with realized gain of 4.80 dBi. Radiating patch of the proposed antenna is designed by modifying conventional rectangular patch by loading a matching stepwise structure. Further, in order to achieve SWB characteristics, the ground plane is reduced with a loaded rectangular notch for better impedance matching. The designed antenna has the advantages of simple planar miniaturized structure, acceptable gain, and wide bandwidth to support various objectives in modern wireless communication. To boost the maximum gain further over the entire frequency band, the proposed antenna is combined with the proposed frequency selective surface (FSS) which acts as a partially reflector surface. The antenna is placed over 4 Â 4 FSS at suitable distance without hampering the obtained bandwidth of the antenna. FSS combined antenna structure, having the physical volume of 56 mm Â 56 mm Â 26.2 mm, exhibits realized gain of 9.3 dBi which is suitable for long range communication. CST MWS (Microwave studio) for simulation results of the suggested antenna and appropriate Microwave Test bench is used to verify the same.

A wideband hybrid microstrip patch antenna with high bandwidth dimension ratio (BDR) is reported in this research work. The electrical dimension of the presented antenna is 0.268λ Â 0.201λ Â 0.01λ, where λ is the maximum operating wavelength of the antenna. The patch consists of one circle and four parallelograms overlapping with each other. The patch looks like a two dimensional "PINE TREE." The fabricated antenna exhibits return loss less than À10 dB from 2 to 15.40 GHz with a percentage bandwidth of 154% and BDR of 2859. Also a peak gain of 3.3 dBi is achieved at 8 GHz. To improve the peak gain further over the entire frequency band, proposed antenna is combined with a mono layer stop band frequency selective surface (FSS). Without disturbing the original bandwidth, the antenna is mounted on top of 16 unit cell FSS arranged in of 4 Â 4 matrix. When FSS is placed at a suitable minimum distance, maximum gain of 7.22 dBi is achieved by the combined structure. Physical dimension of the proposed FSS combined antenna is 64 Â 64 Â 35.2 mm, which is very much suitable for long range wireless applications. Both the antenna and the FSS are designed and simulated using Computer Simulation Technology (CST) software. Also it is fabricated on FR4 substrate. It has loss tangent (tan theta) of 0.02, dielectric constant of 4.4, and thickness of 1.6 mm. All the simulation results have been validated using Vector Network Analyzer (VNA). The measured results exhibit good compliance with the simulated results.frequency selective surface, high gain, hybrid, monopole antenna, wideband | INTRODUCTIONModern day wireless communication technology demands wideband antenna supporting multiple frequency bands with multiple resonant frequencies at the same time. Planar microstrip patch antenna had always been a suitable candidate for wireless communication technologies due to its various advantages like low profile, low cost, and easy integratability with existing systems. But one of the main drawbacks of microstrip patch antenna is narrow impedance bandwidth. But for high data rate wireless communication as well as for high accuracy radar application, high bandwidth has become a necessity. It can be done by increasing channel capacity, and channel capacity increases when

This study presents a new stacked design of reduced size broadband microstrip patch antenna for ultra-wideband (UWB) operation. A folded triangular patch's feeding technique, half V-shaped slot and shorting pins are employed to design the proposed stacked antenna. Shorting pins are applied at the edge of structure to miniaturize the size of the patch. The proposed design with the half V-shaped slot and without stacked patch provides the measured impedance bandwidth (S 11 <−10 dB) of 115.7% (4.35-16.3 GHz) for broadband application. In the proposed design with the half V-shaped slot, the wide bandwidth with an acceptable size reduction is achieved. By adding a stacked element on the upper patch, the impedance bandwidth of the proposed antenna is improved from 3.47 to 17.35 GHz. The stacked design includes a measured impedance bandwidth of 133.3% with reduced sizes of more than 78% compared to the corresponding full design and an enhanced maximum gain of 6.2 dBi. The obtained radiation and impedance results show that the proposed design is applicable for wideband operation. Besides, the effects of some basic concepts and surface currents on the suggested structure are investigated to explain their broadband performance.
