“…The literature indicates that hybrid trapezoidal-elliptical patch where the lower portion of elliptical patch was overlapped by a trapezoidal patch could enhance the impedance bandwidth [7]. Fractal elliptical monopole antenna which resembled the Lorenz fractal shape was proposed [8]. Elliptical shaped fractal patch antenna for multi-band applications was also designed [9].…”

Greater design flexibility and newer miniaturization techniques are highly sought after by the commercial antenna industry and researchers. Micro-Strip Patch Antenna (MSPA) is finding huge applications in various fields of communication. In the present paper, the novel idea of Double-Elliptical Micro-strip Patch Antenna (DEMPA) is proposed for antenna miniaturization and higher design flexibility. Double-Elliptical Patch (DEP) is made as the combination of two half-elliptical patches having the same minor axis and different semi-major axes or the same major axis and different semi-minor axes. A DEP with different lengths of horizontally arranged semi-major axes and centrally given feed was considered here. The length of semi-major axis for right half-elliptical patch was varied while keeping the length of semi-major axis for left half-elliptical patch fixed. Design of DEMPA was carried out using Ansoft HFSS software, and the antenna has been fabricated and tested. The measured results were in good agreement with the simulated ones. The percentage reduction in effective patch area was found to be 8.33 for DEMPA compared to the corresponding elliptical patch antenna. The DEMPA covered the entire frequency range of Ultra Wide Band (UWB). With this novel shape, greater design flexibility along with miniaturization is achieved. The axial ratio analysis showed that the resulted antenna was of linear polarization.

Now a day the requirement of wireless communication increased rapidly with the demand for applications. This leads to the requirement of the design of compact wireless transceiver units. The antenna is one of the major blocks in the design which defines the compactness and efficiency of the unit. In this work, an elliptical patch antenna is designed on the FR4 substrate with εr= 4.2. Again the effect of etching the ground is studied. Also, the effect of inset feeding length studied. In the work, the author discussed various methods to convert a narrow band (NB) antenna into the ultra-wideband (UWB) antenna and wise versa. The proposed antenna can work in ultra band operation from 1 GHz to 12GHz. The same proposed structure can work a wide band of 5.8 GHz bandwidth from 2 GHz to 7.8 GHz with inset feed.

“…Fractals may be used in two ways to enhance antenna designs, one as a design technique for miniaturized antenna elements and the other one as the use of its self-similarity in the geometry to blueprint antennas. A compact fractal elliptical monopole antenna was designed for wide variety of applications like satellite communication transmissions, some Wi-Fi devices, cordless telephones and weather radar systems [34]. The Lorentz fractal shape was introduced on ellipse and thereby multiband applications were achieved.…”

Elliptical Micro-strip Patch Antenna (EMPA) has been emerged as a peculiar and significant category among the different shaped micro-strip patch antennas because of its circular polarization and dual-resonant frequency features with a single feed. Elliptical and its derived shapes such as semielliptical, half-elliptical, slotted-elliptical and elliptical ring are found to be particularly instrumental for bandwidth enhancement and these antennas find great applications in Ultra Wide Band (UWB) and Super Wide Band (SWB) communications. Compared to antennas with circular or rectangular shapes, the design of EMPA is a research area of high potential as there is higher flexibility in its design due to more degrees of freedom. The reported literature in the field of EMPA is very less and there is ample scope for new researchers to work on. This review paper is an attempt to summarize and critically assess the-state-of-the-art design techniques as reported in literature and understand their effects on performance of elliptical patch antenna for suggesting new research fronts in the field of EMPA.
