Abstract The design and simulation of the hexagonal-shaped microstrip patch antenna and its array was proposed in this paper. The structure is capable of operating in the 2.4 GHz ISM band frequency. The 2 × 2 designated hexagonal patch antenna array acts as a radiating element. The designated structure was analysed for the series-fed and corporate-fed manner, and various antenna performance parameters like gain, return loss and bandwidth were measured. The simulated results show that the proposed work significantly enhances the bandwidth and gain than the existing microstrip patch arrays for the ISM band applications.

1 Introduction To meet the demand of distant communication, the wireless systems operating in various frequency bands like L, S, C and X needs appropriate antenna array with good radiation characteristics. The microstrip patch antenna array is mostly preferred for different applications because of its characteristics like less profile, inexpensive, low weight and easy fabrication methods. Due to the necessity of higher gain, the antenna elements increases which results in the complication of the feeding network. Antennas are found to be the significant components in the wireless communication system. The antenna in the wireless system is used for both transmission and V.

reception of the signals. The emerging development towards ease and effectiveness led to the thought of combining microstrip patch antenna into an array of solitary element which could attain radiating tasks and higher gain concurrently.
2 Literature Survey In [1], microstrip patch antenna with hexagonal shape for Wi-Fi application was outlined and they have implemented a suitable technique in designing the filter. In [2], the approach of integrating microstrip patch antenna array with the Chebyshev filter of order three has been discussed [2] and they have showed the rejection of unwanted frequency signals. Three-element Yagi antenna [3] was designed and resulted in the improved performance characteristics by introducing frequency-domain-based filtering approach. In [4], the miniaturized slot dipole antenna with second-order BPF has been designed and experimented. The printed and upturned L-shaped antenna and the parallel coupled microstrip line sections were introduced [5] which resulted in high bandwidth and flat gain response. T
