Abstract-In this paper, a U-shaped microstrip patch antenna with meandered slots is presented. It is designed for biomedical applications to operate at 2.45 GHz. Based on the simulation experience, two designs of the patch are introduced with and without use of meandered slots. The comparative study between these two is also demonstrated. It is observed that the antenna with meandered slots shows good performance with sufficient bandwidth, low losses and is capable of use in biomedical applications. Furthermore, the proposed antenna has small size of 35 * 29 * 1.6 mm 3 , and the size of the ground is only 14% of the overall antenna size. The measured and simulated results show good agreement with each other. The antenna is fabricated on an FR4 substrate, and simulation is carried out on FDTD based Empire XCcel simulator.

A miniaturized serpentine patch antenna is presented for Industrial, Scientific and Medical band (2.4-2.48 GHz) applications. The proposed antenna is fabricated on a Rogers RT/duroid5880 substrate having permittivity of 2.2 and loss tangent of 0.0009. In comparison with other traditional structures, this antenna has an electrical length of 0.961λ with 29.2% impedance bandwidth which is advantageous for higher data rate transmission. In order to test the performance, the proposed antenna is tested in a silicone feeding tube. The simulated and measured results show good agreement with each other. Defected ground structure is also incorporated to enhance the performance of the proposed structure. All the simulations have been carried out on FDTD based Empire XCcel tool.

Vikas et al explained the elliptical disc antenna with defected ground plane for UWB applications and antenna covers the frequency range from 2.94 to 12.57 GHz, similarly B. K. Shukla et al also demonstrated the circular slotted elliptical shaped antenna with elliptical notched ground plane for L and S‐band applications. H. M. Mansour et al illustrated the lotus shaped antenna for ultra wideband communication system from 1.42 to 10.0 GHz.…”

“…By thoroughly reviewing the aforementioned literature, the authors are inspired from the shape of antenna designed in Reference . It has been observed that antenna designed in Reference has explained the elliptical shaped antenna for UWB applications from the frequency range 2.94 to 12.57 GHz but has not illustrated the filtering concept which is required to remove the interference from the UWB frequency range.…”

A novel design of printed monopole antenna for the ultra‐wideband (UWB) applications with band notch characteristics at wireless local area network (WLAN) and X‐band satellite communication system has been proposed in this manuscript. Two different types of feed lines, that is, simple and tapered are used to excite the proposed antenna. Initially, designed antenna is excited by using simple 50 Ω transmission line after that tapered transmission line is introduced to enhance the impedance matching throughout the UWB frequency range (3.1‐10.6 GHz). A comparison of designed antenna with simple and tapered feed line on the basis of impedance matching has also been made in this article, and found that later case reports better impedance matching in terms of Voltage Standing Wave Ratio (VSWR) bandwidth (2.45‐12.0 GHz). Further, the notch bands are embodied into the designed antenna by using two split ring slots and one horizontal slot. The antenna with outer ring slot rejects the WLAN frequency band and antenna with inner ring junks the X‐band satellite communication signal. The notch frequency has been adjusted by optimizing the dimensions of split ring slots as well as horizontal slot, which are incised on the structure of proposed antenna. By adjusting all the parameters of the etched slots of proposed antenna, dual band notched characteristics centered at frequencies 5.4 and 7.4 GHz has been achieved. Designed antenna is also compact (30 × 30 mm2) and capable to suppress the interference of WLAN and X‐band satellite communication signal from the entire range of UWB passband. The proposed antenna is designed on low cost FR4 glass epoxy substrate with 1.6 mm thickness and dielectric constant 4.4. Antenna is designed and simulated by using HFSS V13 simulator and further, it is fabricated and tested for the validation of results. Simulated and measured results are also juxtaposed and found in good agreement with each other.
