“…Koefisien isolasi ini menunjukkan bahwa masing-masing antena bekerja secara independen sehingga dapat meningkatkan penguatan dan kapasitas layanan dari sistem komunikasi (Jiang, W., Liu, B., Cui, Y., & Hu, W. , 2019) . Pada penelitian sebelumnya yang dilakukan oleh (Rafiqul, I. M., Rafiq, S., Yasmin, M. S., & Habaebi, M. H. , 2017) telah berhasil dirancang dan disimulasikan antena mikrostrip MIMO 2 x 2 elemen pada frekuensi kerja 3.5 GHz dengan nilai koefisien refleksi ≤ -10 dB, namun nilai koefisien isolasi masih berada pada rentang ≤ -15 dB pada frekuensi kerja yang diharapkan. Penelitian ini mengusulkan desain antena mikrostrip MIMO dengan 2x1 elemen yang dioptimasi menggunakan teknik inset dan slit.…”

The fifth generation (5G) technology offers high speed communication systems and requires a multi input and multi output (Multiple Input Multiple Output / MIMO) antenna system to increase customer capacity. This research proposes a microstrip antenna design for a fifth-generation (5G) communication system that works at a frequency of 3.5 GHz. The antenna was designed using the RT-Duroid R5880 substrate type with dielectric constant (Îµr) = 2.2, thickness (h) = 1.57 mm and loss tan (tan Î±) = 0.0009. To produce optimal parameter, the antenna is optimized using slit on the edge with a total of 2 pairs. The addition of an inset aims to reduce the reflection coefficientÂ of the proposed antenna. From the simulation results, the reflection coefficient value is -25 dB at a frequency of 3.5 GHz with a bandwidth of 220 MHz. The gain of the proposed antenna is 10 dB at a frequency of 3.5 GHz. The isolation coefficient obtained is -70 dB with a distance between (d) = 43 mm. The application of the MIMO antenna increases the gain by 49.52% compared to the single element microstrip antenna.

“…Multiple Input and Multiple Output (MIMO) antenna arrays have generated interest due to their straightforward construction and superior performance. In a MIMO array, it is feasible to use the entire antenna array at once, but it is also conceivable to use a subset or a single element of the same array for various purposes, such as separate In [9], [10], a 22 MIMO array with DGS has been suggested. Circular polarisation was obtained and MC was reduced by using slots on the radiating patch.…”

To design a single element microstrip patch antenna at a frequency of 4 GHz. A uniform planar array with 4 patch elements is designed. A non uniform planar array is designed to overcome the mutual coupling effect. Simulation of the designed uniform planar array and non uniform planar array antenna array is performed on HFSS tools. A single microstrip feed patch antenna element is designed at a frequency of 4 GHz. The substrate material used is Rogers 6002. A 2*2 array is designed by using 4 similar patch elements. The proposed model has dimensions of the substrate as 58mm x 68mm, the dimensions of the patch is 20mm x 22mm. For the proposed model slots are added to each patch with the dimensions 5mm x 1mm. The substrate material used is FR4 epoxy. It is further improved by changing the dielectric material variations, slot arm length variations, slot arm thickness variations.

Abstract. This paper describes temperature measurement in the multisensor systems based on the radio-frequency identification SAW passive tags which are currently applied in the electric power systems and the switchgears. Different approaches of temperature measurement in the collision case are shown here. The study is based on the tag model with specific topology, which allows us to determine temperature through the response signal with time-frequency information. This research considers the collision case for several passive tags as the temperature sensors which are placed in the switchgear. This research proposal is to analyze the possibility of using several SAW passive sensors in the collision case. We consider the using of the different typical elements for passive surface acoustic wave tag which applies as an anticollision passive sensor. These wireless sensors based on the surface acoustic waves tags contain specifically coded structures. This topology makes possible the reliability of increasing tag identification and the temperature measurement in the collision case. As the results for this case we illustrate simultaneous measurement of at least six sensors. IntroductionModern solutions in the field of monitored parameters should meet the requirements of increased noise immunity. In addition, they should have high speed, resistance to external climatic influences, high reliability and durability in operation. Modern monitoring based on radio frequency systems should be passive (without any energy source). Such requirements are met by radio frequency identification (RFID) technology, based on the use of passive acoustoelectronic devices on surface acoustic waves (SAW) [1], [2].For temperature monitoring, RFID reader interrogates several passive SAW tags which are placed on the monitored object. However, in the simultaneous monitoring of several temperature sensors is limited to the problem of collision for passive acoustoelectronic RFID devices. In the case when several sensors are interrogated simultaneously, their response signals can overlap each other in the time domain, making it impossible to read the code of each device and obtain information about the temperature.The last analysis shows that solutions cannot satisfy the actual tasks of monitoring and control objects with a wide temperature range and certain operating conditions in the collision case. This problem is the most evident in multisensory systems which are using the electric power systems. The temperature is the most important indicator of the electrical equipment current status. It makes possible to provide information about the emergency and electrical fire caused by short circuit or overheating of the equipment in the switchgear. Monitoring systems which are applied for temperature measurement would increase reliability and safety of high-voltage equipment.
