This paper presents the design, simulation, realization and analysis of flexible microstrip patch antenna for S-band applications. The proposed design also adopts the conformal structure by utilizing flexible substrate. Conformal or flexible structure allows the antenna to fit with any specified shape as desired. The antenna patch dimensions is 43 mm × 25 mm without SMA connector. The patch is etched on the flexible dielectric substrate, pyralux FR 9111, with a relative dielectric constant of εr = 3 and the thickness of substrate, h = 0.025 mm. The antenna is designed to resonate at 3.2 GHz. The return loss (RL) of the simulation is -35.80 dB at the center frequency of 3.2 GHz. The fabricated antenna prototype was measured at different bending angles scenarios including 0º, 30º, 60º, and 90º. The measurement of antenna prototype shows that the center frequency is shifted to the higher frequency of 3.29 GHz, compared to the simulation result. Among these scenarios, measurement at bending angle of 90º gives the best performance with RL = - 31.38 dB at 3.29 GHz, the bandwidth is 80 MHz, and the impedance ZA = 48.36 + j2.04 Ω. Despite a slight differences from simulation results, the designed antenna still performs well as expected.

“…Pengembangan antena mikrostrip untuk sistem komunikasi 5G yang bekerja pada frekuensi 3,5 GHz telah dipaparkan pada penelitian sebelumnya (PARAGYA & SISWONO, 2020;Sumpena et al, 2020), namun dari kedua penelitian tersebut antena hanya dirancang untuk bekerja pada satu frekuensi kerja saja yaitu 3,5 GHz sehingga tidak dapat digunakan untuk sistem komunikasi yang berbeda. Penelitian (Hanafiah et al, 2016;Rhee, 2016;Wali et al, 2014) telah berhasil merancang antena mikrostrip frekuensi ganda yaitu dengan menggunakan metode slot tunggal dan metode Y slot dan didapatkan bahwa (Sumpena et al, 2020) yang menghasilkan antena mikrostrip untuk sistem komunikasi 5G yang hanya bekerja pada satu frekuensi saja dengan menggunakan metode Y slot (Wali et al, 2014) sehingga menghasilkan frekuensi ganda dan menambahkan inset feed untuk optimasi return loss (Darmawan et al, 2018).…”

This research proposes the design of dual-frequency microstrip antenna using the Y slot method. Antenna are designed with a working frequency of 3,5 GHz for 5G and 5 GHz communication systems for Wi-Fi using RT duroid 5880 substrates with a constant value in electricity of 2,2, a thickness of 1,575 mm and a loss of tangents of 0,009. The Y slot method is used to generate antenna that can work on dual bands and then add inset feed to the antenna in order to optimize the return loss value of the proposed antenna. From the design and simulation has been successfully obtained antennas that can work at frequencies 3,5 GHz and 5 GHz. The addition of inset feed on the antenna results in a return loss value for the frequency of 3,5 GHz which is -17,86 dB and a frequency of 5 GHz which is -36,27 dB. Inset feed renching on antenna design using Y slot method successfully optimizes return loss value at 5 GHz frequency of 54,34% compared with single element antenna.

Now, wireless communication is in the 5G era. As the wireless communication technology grows rapidly, the devices are directly connected to the internet through wireless medium. This device requires high speed communications. In order to fulfill this requirement, researchers have to improve the bandwidth of transmitting and receiving antenna in the existing design. This paper gives the clear view of bandwidth enhancement by using Taconic TLX-9 substrate material of dielectric constant 2.5. With the help of CST Studio Suite Simulation Tool, a rectangular microstrip antenna was designed under the operating frequency of 3.5 GHz using three different substrate materials such as FR 4, Rogers RT 5870, and Taconic TLX-9. To improve the bandwidth, a proximity coupled feeding technique was used in this proposed model. An analysis was performed with this substrate material. This analysis concludes that the Taconic TLX-9 substrate material gives the bandwidth of 593.7 MHz at a return loss of -35dB. The maximum gain of 7.1dB was achieved under 3.5 GHz and also 6.823 was obtained under 3.5 GHz. The proposed antenna design can be used for 5G application (mid band). Further, the bandwidth, gain, directivity, return loss can be improved by introducing parasitic elements, arrays, SIW concepts etc.
