RF front-end system in the mobile communication system consists of an antenna, filter, and amplifier section. Now a day, there is a need to reduce the size of this RF front-end system. Here the challenge is the reduction in the size of the RF front end without degrading the performance. One way to reduce the size is by reducing the size or area of the antenna. This work proposes and simulates three Bio-inspired microstrip (BIMS) antenna designs. They are flower, Butterfly, and leaf shapes presented based on the perturbation method, Gielis super formula, and modified polar transformation models, respectively. These BIMS antennas were printed on fiberglass laminate (FR4) as substrate with a dielectric constant of εr = 4.4 and a loss tangent of 0.02. The simulation results cover parameters of the antenna, such as reflection coefficients (S11), surface current density (Jsurf), and radiation patterns. They offer a maximum gain of 14 dBi, 8 dBi, and 4dBi, respectively, and their results are compared with other works. These antennas are less in size, so they occupy less area compared to conventional rectangular or circular patch antenna, which radiates in L and S bands at different frequency ranges.

The proposed work, a filtenna for s band application is implemented. It is designed by embedding an Interdigital band pass filter (IDBPF) and leaf shaped antenna which are operated in S band. The IDFBPF is having seven resonators with one end shorted through dual vias. It offers a bandwidth of 1.3GHz from 1.65GHz to 2.95GHz. A Dumbbell shaped DGS (Defected Ground Structure) provided in ground to improve the filter characteristics. Measured pass (BRL) band return loss (S11) & insertion loss (S12) are -18dB & -4.6dB correspondingly. Further, leaf shaped antenna is designed based on modified polar transformation equation; it has 2.7 GHz bandwidth from 1.3 GH to 3 GHz and has a gain of -5.45dBi, and return loss (S11) of -19.5 dB. The filtenna is obtained by integrating the IDBBPF in the fodder line of the leaf designed antenna. The final model has 1.2 GHz operating bandwidth from 02.30 GHz to 03.50 GHz with peak arrival damages at 2.4GHz and 3.1GHz with -20dB and-24dB respectively. The designed filtenna has a pass band gain of -5.3dBi. The shift in operating band is due to combining the filter with antenna. The proposed model is invented on FR4 substrate having a wideness of 01.60 mm and having a dimension of 0.25 0.58 ?02. In this final model two complementary slip ring resonators (CSRR) are used in addition with four dumbbell structures as defects in the ground plane to avoid ripples in return loss (S11) graph. A high degree of concordance exists between empirically measured and simulated outcomes. The radiation band is showing its application in S band wireless mobile communications, Wi-Fi and ISM 2.4GHz band.

“…Ultra wide band technology is on more demand now a day due to its attractive features. The applications of UWB include GPR, military, microwave imaging, radars etc due to its huge capacity, powerful penetration and accuracy [20]- [22], [34]- [36].In GPR system antenna frequency is one of the prominent factors which decide the performance of the system.GPR system comprises 3 components radar gram, antenna and power supply. The control unit or radar gram emits electromagnetic radiation in to the surface of investigation, the reflected signal is collected by the antenna and display results on screen which helps GPR operator to determine results accurately.…”

ABSTRACTGround Penetrating Radar (GPR) is one of the capable technologies for exposure and recognition of both metallic and non metallic objects masked under the ground. Bandwidth is one of the parameter for GPR system performance, very high frequencies are required for better resolution of microscopic objects. Ultra wide band GPR system can able to meet the current requirement with more efficiency. An Anti-podal Vivaldi Antenna (AVA) is proposed such that its operating frequency range varies from wideband to ultra wide band. A novel approach of designing Anti-podal Vivaldi Antenna is designed to increase the performance characteristics like gain, frequency of operation, radiation pattern, to reduce return loss, to reduce side lobes levels and to reduce the fabrication cost. In order to reduce the cost of fabrication, the substrate material preferred as denim material. The reason for choosing denim material is, it can be easily incorporated and it is homogeneous in nature. Anti-podal Vivaldi Antenna is designed, simulated using HFSS software and it is fabricated. The results obtained in the simulation process and the fabricated antennas are very relative to each other. The performance characteristics measured by simulation process achieves a maximum gain of more than 7dB and practical antenna achieves around 6.92dB with an operating frequency range from wide band to ultra wide band range from 5.2GHz to 13GHz.
