“…A comparative study of results for different geometries of patch for X-band at different resonating frequency is detailed in Table 3, table also limelight on better performance of our antenna over other fabricated designs. [12][13][14].All are recent designs using circular patches and rectangular patches but with higher dielectric values degrading the efficiency. Last result outperform our design's figure of merit above mentioned parameters but it comes at cost of lower efficiency (0.85) for resonant frequency in compare to our 0.97 at the resonant frequency.…”

This paper presents a simulated design of high performance elliptical ring Microstrip patch antenna at resonant frequency of 8 GHz for radar. Owing to its intrinsic geometry elliptical ring patch is found to be suitable candidate for designing high power, large gain and better efficiency conformal antennas for radar at X-band or even higher frequencies. Simulated antenna shows very high average gain of 7.5 dB for entire bandwidth of 340MHz i.e. 4.25% impedance bandwidth. Simulated results shows very good return loss performance, S11 parameter is-42.5 dB at resonant frequency. Roger Ultralam 2000 substrate is used to design the antenna. Average radiation efficiency of antenna is very high (97.9%). Design show great promise for radar application with no side lobes, high directivity of 7.71 dB at 8 GHz & very high front to back ratio. Comparative study of recent works in X-Band and our design is presented & variation of return loss with dielectric height is also elaborated in paper.

“…But still it has research issues like narrow bandwidth, poor efficiency, low gain and power handling capacity. Motivated by these research issues, Novel DB-RPA antenna is designed and it can be rapidly used in various fields of communication for their compact size, high performance and versatility (Deb, Moyra, and Bhowmik 2015). The proposed antenna is designed using Duroid substrate.…”

Aim: Microstrip patch antennas are rapidly used in the areas of wireless systems due to its low cost and lightweight. But still it has research issues like narrow bandwidth, poor efficiency, and low gain. The objective of this study is to enhance the gain of Novel DB-RPA antenna. This work presents the comparative analysis of gain enhancement between rectangular and circular patch antennas. Materials & Methods: Dual band rectangular patch antenna (DB-RPA) and circular patch antenna (CPA) are designed to enhance the gain of the antenna by using HFSS software and by collecting the dataset of 40 samples with pretest power of 80%. The gain of CPA is 1.89 dB and DB-RPA is 4.66 dB. The directivity of CPA is 3.52 dB and DB-RPA is 4.89 dB. Results: On performing an independent sample t-test on the two groups considered, it appears that the mean gain of Novel DB-RPA is 3.0755 and CPA is 0.8820 with significance value of 0.001 (p<0.05). Conclusion: From this study, it is found that DB-RPA design appears to have 71% higher gain and 58% higher directivity with comparison of CPA design.
