Directivity and bandwidth enhancement of innovative sleeve dipole array antenna and comparison with microstrip patch antenna for submarine communication.

The aim of this work is to design an Innovative sleeve dipole array antenna with high directivity and gain. Materials and Methods: For comparison the two antennas are separated into two groups. Group 1 is considered as a sleeve dipole array antenna and group 2 is considered as a microstrip patch antenna. Initially 10 samples are taken from each group but for accurate comparison sample size is taken as 6 for each group. The significance obtained was 0.01 (p<0.05). The alpha value is 0.05 and the beta value is 0.2 and the gpower value is 0.8. Results: The simulated results that are obtained in FEKO software are, directivity for the sleeve dipole array antenna at 2.4GHz is 10.57dBi and for microstrip patch antenna the directivity is 6.48dBi. The bandwidth for sleeve dipole array antenna is 0.61GHz and for microstrip patch it is 0.12GHz. Conclusion: By analyzing all the obtained results, the sleeve dipole array antenna will perform better than microstrip patch antenna for submarine communication. [ABSTRACT FROM AUTHOR]
