This paper investigates the comparison between existing antennas based on microstrip fractal technology with the proposed antenna. Comparison of proposed antenna has been made on the basis of number of frequency bands of operation and bandwidth. Proposed antenna is designed on the substrate of FR4 glass epoxy material with 1.6mm thickness and 4.4 dielectric constant. HFSS V13 simulator is used to design and simulate the proposed antenna. By observing the results of proposed antenna and existing antennas; it has been depicted that proposed antenna works on seven frequency bands of operation as compared to the existing antennas. Proposed antenna exhibist wideband characteristics and shows the bandwidth of 1959MHz, 700MHz and 2970MHz for respective frequency bands of operation. So, the proposed antenna can be efficiently used for practical wireless applications due to its wideband characteristics and more number of frequency bands of operation.

“…Extensive research has been carried out in the field of microstrip patch antennas. Some of them has been discussed in this work such as; double C shaped microstrip antenna has been designed for UWB applications and exhibit the gain of 6.18dB with a narrow bandwidth of few MHz [12], a triple band stacked patch antenna uses the slotted ground structure having a narrow bandwidth with a maximum gain of 5.8dB [13], rectangular antenna has been designed for WLAN applications to achieve the gain of 3.35dB at 2.45GHz frequency band, it also shows the bandwidth of few MHz [14], rectangular microstrip antenna with truncated corners using T and U shaped slots have been designed for single frequency band of operation and exhibit narrow bandwidth [15], compact size slotted microstrip patch antenna is designed for multiband operation with a gain of 2.8dB and bandwidth of 500MHz, 400MHz and 550MHz [16], L-shaped slotted patch antenna is designed for bluetooth, WLAN, WiMAX applications and does not give any detail about the gain and bandwidth of antenna [17] and multiband fractal antenna array for wireless power transmission has been designed to achieve a gain of 2.47dB and 4.30dB with a bandwidth of 370MHz and 550MHz [18]. Microstrip patch antennas are designed by using hybrid fractal slots which report wider bandwidth 2260MHz and 2440MHz [19].…”

This manuscript presents the novel design of rectangular microstrip patch antenna based on fractal techniques for wideband applications. In this design, T-slots are introduced in rectangular patch geometry by varying the dimensions of slots which follow the concept of fractal properties. The HFSS V13 software is used to design, simulate and analyze the proposed antenna. Low cost FR4 glass epoxy substrate with thickness 1.6mm and dielectric constant 4.4 is used to design the proposed antenna at resonant frequency of 2.45GHz. Proposed antenna efficiently works on four frequency bands (2.0GHz, 6.5GHz, 8.4GHz and 9.7GHz) with acceptable value of gain, returns loss and also reports wide bandwidth. It exhibits the good omnidirectional and bi-directional radiation pattern at the frequency band of 2.0GHz. Proposed antenna can be used for different wireless applications such as point to point high speed wireless communication (5.925GHz -8.5GHz), bluetooth (2.41 -2.49GHz) and X-band application.

“…Introduction: In recent years, a large number of researches have dedicated to attaining tri-band antennas but only a few studies focus on tri-band antennas with dual polarisation or omnidirectional radiation patterns [1][2][3][4][5][6]. The antennas proposed in [1][2][3] feature three bands and dual polarisation, but they are not suitable for applications in unmanned aerial vehicles (UAVs) owing to the unidirectional radiation patterns.…”

A new tri-band dual-polarised omnidirectional antenna is proposed. The dual-polarised antenna consists of a metal cuboid body with a vertical slot for horizontal polarisation (HP) and a rectangular back metal cavity with two folded horizontal slots for vertical polarisation (VP). A metal HP feedline is employed to coupling feed the vertical slot while a metal VP feedline is used to excite the two horizontal slots. Due to the coupling feed and the orthogonality between the vertical and horizontal slots, the dual-polarised antenna features three bands and a high isolation. Experimental results show that the tri-band dual-polarised antenna covers the Chinese Unmanned Aircraft System bands (840.5-845, 1430-1444 and 2408-2440 MHz) with reflection coefficients <−10 dB and isolation >32 dB. Good omnidirectional radiation patterns are observed for both HP and VP.
