The proposed antenna improves the fractional bandwidth, gain and directive radiation pattern when compared with existing reported work in literature [22]- [24], [29]- [31]. Hence, the design antenna is useful for wall imaging and radar system.…”

A compact circular ring antenna with defected ground structure (DGS) has been design for Ultra-Wide Band (UWB) applications. Initially, a circular patch antenna is design by introducing a rectangular DGS structure. Further, slot has been inserted in circular patch to improve the impedance bandwidth. The proposed design covers the frequency range of 2.4-10.4GHz below -10dB. Proposed antenna has design and fabricated on FR -4 substrate having 1.5mm, 4.3 thickness and dielectric constant, respectively. The performance of the designed antenna is analyzing with optimized dimensions in terms of return loss, VSWR, radiation pattern, gain characteristics, group delay and surface current distributions. Further, performance analysis of the proposed antenna has also been compared with existing suggested antennas in literature with compact in size. The fabricated antenna shows a good result with simulations software.

“…Owing to its diverse merits, several researches are going on now a days to design and develop application specific FSS to fulfill its applicability in various modern applications such as electromagnetic shielding, 2 polarizers, 3 absorbers, 4 RFID, 5 cloaking, 6 radomes, 7 reduction of radar cross section 8 and satellite communication 9 . One more modern use of FSS can be noted as antenna gain augmentation when it is integrated to the antenna 10‐21 . Design of wideband FSS 11‐21 finds special research attention as broadband and ultra‐wideband (UWB) antennas offer usually low gain profile 22 .…”

A simple structured single layered frequency selective surface (FSS) that has unit cell size of 11 × 11 mm2, substrate thickness of 0.8 mm only and capable to work in a very widespread band from 0.001 to more than 17 GHz is proposed in this article. The FSS is competent to augment the gain of a UWB monopole antenna by 2 to 3.5 dBi when integrated at the back of antenna. The performances of “antenna‐FSS” structure is evaluated by simulation and experimental measurement where good correlations are obtained. The integrated structure provides wide impedance band (S11 < −10 dB) from 2.82 to 19.94 GHz (more than 150%) with improved broadside radiation and high radiation efficiency profile. The transient and frequency domain characteristics of “antenna‐FSS” composite structure are also evaluated in close proximity of diverse sub‐surfaces such as dry sand, wet sand, wood and concrete where an almost unaltered impedance band profile, linear transfer function response and non‐varying group delay responses are achieved which establishes the applicability of the composite structure in ground penetrating radar for low depth sub‐surface scanning applications.

“…Yet, monopole antenna showed poor gain and directivity with low profile. Several methods have been proposed to improve the monopole antenna gain with techniques designing the radiate element in the array configuration [7] or by placing Frequency Selective Surface (FSS) [8], Artificial Magnetic Conductor (AMC) [9] underneath the antenna as a reflector. The radiating patch designed in the array configuration changed the monopole antenna design to become complex.…”

This paper presented the effects of Defected Waveguide Structure (DWS) toward wideband monopole antennas. Ultra-wideband (UWB) technology was introduced to support high data rate and maximum bandwidth utilization. Monopole antenna received great attention owing to its appealing features of planar in the structure and is easy to manufacture in miniaturized sizes. Yet, poor gain and directivity are always the drawbacks of the miniaturized antennas. It was found that there was no research work done on the monopole antenna design with DWS. Two wideband monopole antennas with a microstrip feed line and coplanar waveguide (CPW) feed line were proposed. Two waveguides with full copper and square DWS were designed at all the inner walls. Monopole antennas were then integrated in the waveguides. The antenna parameters studied were return loss, efficiency, gain, directivity and radiation pattern to investigate the effects of DWS toward monopole antennas. Both monopole antennas achieved wide bandwidth from 2.5 GHz to 11 GHz and higher efficiency of more than −2 dB. Monopole antennas with waveguide presented a narrower bandwidth from 6 GHz to 11 GHz but a significant directivity improvement of 5 dBi at a lower frequency of 4.5 GHz. Monopole antenna with square DWS demonstrated high directivity and gain in a wide bandwidth of 8.5 GHz. Higher gain was improved around 4 dB at the frequency of 4.5 GHz, and high efficiency of more than −2 dB was achieved. The DWS design served as a guide for future communication system based on the smart technology system.
