This article proposes modified fractal antennae for wideband applications. The proposed antennas have a resonance frequency range of 10–40 GHz. Modified fractal antennae are designed and fabricated with a height of 1.6 mm, substrate width, and length of 35 mm2. The simulated result shows that the peak gain is increased by 6–8 dBi for the proposed designs DGS 1 and DGS 2 concerning fractal antennae FA 1 FA 2. Based on the proposed designs, the designed DGS 1 and DGS 2 antennae radiate power with a peak directivity of 8.58–13.3 in dBi concerning fractal antennae FA 1 FA 2. The proposed antennas with expected 6G and 5G NR bands have more radiation concerning resonate frequencies such as 14, 30, and 37 GHz, and 14, 17.1, 19.5, 30, 33.2, and 36.92 GHz in the 10–40 GHz range with Phi = 0°, Phi = 90°, and Theta = 90° concerning designs DGS 1 and DGS 2. At frequencies in the mm‐wave range, the antenna has more fluctuations, and current distribution is concentrated on fractal slots, in which antennas have more radiation. Proposed antennae have pencil beam properties required for advanced 5G mm‐wave communication. A more radiating antenna has a maximum return loss of 27 and 30 dB for designs DGS 1 and DGS 2, respectively. Moreover, the bandwidths covered in the 5G NR and expected 6G frequency ranges are 13.5–16.8 GHz, 27–38.1 GHz, and 12.63–14.68 GHz, 15.3–40 GHz, concerning designs DGS 1 and DGS 2. The proposed antennae have multiband, which cover more applications in the n257, n258, n259, n260, and n261 5G NR bands and expected 6G bands with the ground‐based radio navigation applications, and so forth. The proposed fabricated antennas also cover 5G and expected 6G applications with good matching. The proposed antennae have been simulated using CST, and the results of the fabricated antenna have been validated using the vector network analyzer, spectrum analyzer, and power sensor.

“…Nevertheless, the insertion of (or cutting) a slot in the patch section itself has proven to be more useful and practical in enhancing the antenna performance. Such approach has been demonstrated in several researches for various frequency bands including WiMAX, WLAN, 3G, microwave, radar, and other application bands [1,2,4,6,[22][23][24][25][26][27][28][29][30][31]. All these researches used slots in rectangular or circular patch shape with a ground plane being located in the back surface of the antenna.…”

Microstrip patch antennas are attractive for communication applications due to their small size, low cost, and easy fabrication. Regardless of the diverse usage of these antennas, their bandwidth and efficiency are still limited and need to be improved. Therefore, this paper aims to enhance the bandwidth and efficiency of a microstrip antenna by inserting a slot into various patch designs. Flame Retardant (FR4) material is used in the dielectric substrate and the antenna is fed by a microstrip line. Virtually, the antenna performance is attempted to be optimized through empirical investigations of feedline lengths, slot sizes and positions, and ground plane dimensions and locations. To achieve the results, the High Frequency Structure Simulator (HFSS) is used, and the paper concludes by showing that the antenna performance is enhanced by the slot, and the return loss is significantly reduced when the ground plane is moved to the front surface of the antenna.

An experimental study of microstrip patch antenna designed and fabricated on FR4 epoxy substrate is presented. Further a performance comparison of designed antenna is made with proposed design using Gallium doped Ba-Sr hexagonal ferrite substrate. Microstrip feed line is used for inputting the signal to antenna. The whole simulation is done on HFSS simulator (version 13.0).The center frequency for proposed antenna is 10GHz and is optimized for significant performance parameters viz return loss, bandwidth, VSWR and gain. It was observed that the designed antenna provides better results with ferrite substrate as compared to FR4 epoxy substrate showing -10db broad bandwidth of 4.2GHz in the frequency region 8.2GHz to 12.4GHz. Although, the results of other parameters like return loss, VSWR and gain are found to be optimum with FR4 substrate as compared to mentioned ferrite substrate. The prototype of proposed antenna with FR4 epoxy substrate is fabricated and tested to attain the experimental results. The measured results are found to be better than simulated results. Thus the proposed antenna structure can be considered suitable for microwave communication application in X-band.
