Results and Discussion The microstrip patch antenna has been designed and the obtained results are scrutinized using Ansys HFSS v.15.0 software. The results are obtained based on the desired frequency. The return loss obtained for the frequencies of 23.9GHz, 35.5GHz and 70.9GHz are -19.9737,-22.7307 and -21.9667 respectively as shown in fig x. To obtain the higher transmission efficiency it is recommended to choose higher gain more than -10db. To evade the mismatch between an antenna and feed line it is essential to get VSWR between 1 to 2 virtually[26]. The VSWR of 1.7483, 1.2709 and 1.3881 are obtained for the profound frequencies as shown in Fig 4. The radiation pattern for designed frequencies is plotted in the E and H plane as shown in Fig 5. The radiation pattern for the obtained frequencies is resolute and has a favourable gain of 4.435, 3.6602 and 5.6402 for frequencies 23.9GHz, 35.5GHz and 70.9GHz as observed in Fig 6(a)(b)(c) respectively. At the resonate frequency the surface current distribution is observed over the patch and feed as displayed in Fig 7. Fig. 3. return loss versus frequency. The return loss of antenna should always be lesser than -10dB. The antenna is designed based on applications in the field of radiolocation, satellite communication, space research, radio astronomy, and mobile communication. The frequencies obtained are of larger bandwidth which allows us to utilize the designed antenna for multiple purposes. The appreciable bandwidth if the antenna allows its application in radiolocation to pinpoint the location of each vehicle within the bandwidth. Obtained return losses along with their respective gain justifies the application in 5G communications. Further, the radiation pattern satisfies the application in space applications. The efficient link between satellites and the major and minor stations on the earth is vital for fast, low latency communication. Space research has been an emerging domain of public research in the field of science[27]. Utilizing an efficient antenna for such mission-critical purposes will strengthen the Intra and Inter Communication between the man-made objects in the space[28][29]. As such, the antenna designed can also be easily 2084 S Punith et al. / Procedia Computer Science 171 (2020) 2080–2086 Mohammed Riyaz Ahmed et al. / Procedia Computer Science 00 (2019) 000–000 5 Fig. 4. VSWR of the antenna must practically be between the values of 1 and 2. Fig. 5. Radiation pattern sweep in 360 0 angle Fig. 6. Gain gives the radiation efficiency of the antenna in space configured to be utilized for mobile communication where there is a necessity for higher frequencies for its usage in 5G communication. 6 Mohammed Riyaz Ahmed et al. / Procedia Computer Science 00 (2019) 000–000 Fig. 7. Current Distribution is a qualitative measure of how the current flows in the entire antenna. 4. Conclusion This work focuses on the design and simulation of a microstrip patch antenna. Many applications such as radiolo- cation, radio astronomy, mobile and satellite communication and space research are taken into consideration and the antenna is designed specifically for these applications. The antenna works at three frequencies. 23.9GHz of frequency finds application in space applications such as radio astronomy and satellites. The frequency of 35.5GHz is applied for radio location. Further, 70.9GHz finds its way in 5G mobile communications. The antenna is compact and consumes less power. Justified return loss, positive gain makes the antenna suitable for all the aforementioned applications. The future work would include fabricating the antenna and verifying the obtained results in the real environment. The low gain, narrow bandwidth, low efficiency and low power of the antenna have to be taken care of.
