“…However, for optimum use in radar applications the radiation efficiency pattern of an antenna is also an important parameter. The radiation pattern must be fairly widespread [3] in order to be able to detect objects in the immediate surroundings of the antenna. High directivity is undesirable.…”

“…It is similar to the David antenna proposed in [8], where on the design of hexagonal patch the fractals are made which as a result leads to increase in the bandwidth of the antenna. Modifications to the design are inspired from the configurations proposed in [1], [2], and [3]. The antenna is etched on an FR4-epoxy substrate since it is very economical to use.…”

This paper proposes a unique micro-strip patch antenna which has a hexagonal fractal pattern which can mainly be used for ground based surveillance radar applications. To further optimize the functioning of the antenna, multiple slots have been added to the ground plane, and a stepped pattern has been implemented to increase the current density and the gain. A detailed study of the stages of development of the antenna has been made, illustrating the effect that various design elements have on the operating characteristics of the final design. There is specific emphasis on the use of slots in the ground plane. Variations in return loss, gain, VSWR, operating frequency and bandwidth with changes in the design of the ground plane have been documented. The antenna is designed to perform in the X-band, more specifically around 9 GHz, making it well suited for short range search. The final iteration of the antenna design, including various stages of slotting in the ground plane, works at 8.7 GHz, which is well within the X-band range, and has a return loss of around 30 dB.

An inscribed hexagonal fractal slotted patch antenna with some additional geometry and slots is proposed for the optimization in this paper. This research work is concerned with the optimization of this slotted fractal antenna with the help of the curve-fitting method in conjunction with the modified version of Lightning Attachment Procedure Optimization (MLAPO) technique. The data required for the curve-fitting technique and for the optimization technique have been obtained by varying some of the parameters of the proposed antenna. Different equations are developed to know the relations between these parameters of the proposed antenna. The MLAPO technique is applied thereafter to calculate the different optimized geometrical parameters to optimize the bandwidth for the proposed antenna. The optimized geometrical parameters are verified with the help of a parametric variation to justify the reliable optimization. The bandwidth obtained by the MLAPO technique has been found to be better than that obtained by PSO and normal LAPO algorithm. The prototype of the optimized antenna is fabricated and the experimental results are found to be compatible with the results obtained by simulation. The proposed optimized antenna may be utilized in various applications in C and X bands.
