“…Pada penelitian yang dilakukan oleh (Dhengale, B. B., & Karia, D. C., 2015) diperoleh nilai gain sebesar 7,5 dBi dengan menggunakan metode array 2x2, sedangkan pada penelitian yang dilakukan oleh (Dalvi, S., Jagtap, S., Yadav, V., & Gupta, R. K., 2016) metode array 4x4 berhasil meningkatkan efisiensi nilai gain dari 12 dB menjadi 15,8 dB. Dari hasil penelitian sebelumnya dapat ditarik kesimpulan sementara bahwa metode truncated corner dapat menghasilkan polarisasi melingkar dengan axial ratio ≤ 3 dB dan metode array dapat meningkatkan penguatan (gain) antenna.…”

ABSTRAKPenelitian ini mengusulkan desain antena mikrostrip array empat elemen dengan polarisasi melingkar pada frekuensi kerja 2300 MHz untuk aplikasi 4G/LTE. Antena telah dirancang dan dipabrikasi menggunakan substrat jenis FR-4 Epoxy dengan nilai konstanta dielektrik (Ɛr) = 4.3, ketebalan substrat (h) = 1.6 mm dan loss tangen (tan δ) = 0.0265 dengan pencatu microstrip line. Polarisasi melingkar dengan axial ratio ≤ 3 dB dihasilkan dengan menggunakan metode truncated corner sedangkan untuk meningkatkan nilai gain digunakan metode array empat elemen. Dari hasil proses pengukuran diperoleh nilai koefisien refleksi sebesar -16.52 dB, VSWR sebesar 1.37 pada frekuensi kerja 2300 MHz dengan bandwidth yang diperoleh dari hasil pengukuran adalah 400 MHz (2050 MHz - 2450 MHz). Metode truncated corner berhasil menghasilkan polarisasi melingkar dengan nilai axial ratio 1.745 dB dan berhasil menghasilkan nilai gain sebesar 9.04 dB pada frekuensi kerja 2300 MHz untuk aplikasi LTE.Kata kunci: Antena, mikrostrip, koefisien refleksi, array, truncated corner ABSTRACTThis research proposed a four-element microstrip array antenna design withcircular polarization at a working frequency of 2300 MHz for 4G / LTEapplications.

“…But it is not a robust structure and hard fabrication in the manufacture, especially for small antenna [5], [12], [14]. Meanwhile the array of patches is a good technique to enhance directivity; however, its drawbacks are the large area and requirement of a complex feeding network [9], [12]. Otherwise, the reactive impedance surface acts as a perfect reflecting electric or magnetic surfaces.…”

“…Otherwise, the reactive impedance surface acts as a perfect reflecting electric or magnetic surfaces. The reactive impedance surface decreases the interaction between the feed patch and its substrate, which results in suppressing of surface waves and improving in impedance matching and antenna efficiency [9], [12], [15]. The disadvantage of the reactive impedance surface is a complex structure with numerous cells that raises the design period and cost of antenna.…”

A compact and high gain resonant cavity antenna (RCA) is investigated in this work. At first, a ray-tracing model and the full-wave analysis are presented to clarify the characteristics of RCA in cases of finite lateral size and inhomogeneous superstrate. In consequence, a novel compact, high gain, and wideband RCA is proposed. The RCA consists of a via hole feed patch and an array of hybrid parasitic rings fabricated on a superstrate. The via holes feed patch with a high radiation directivity significantly enhances the RCA's gain. On another hand, the dimension and bandwidth of the RCA are improved by the hybrid parasitic ring superstrate which is constituted by non-periodic parasitic patch and rings. Finally, a prototype of the RCA is fabricated and measured. With only the dimension of 1.35λ 0 × 1.35λ 0 × 0.63λ 0 , the peak gain of 15.8 dBi and 3 dB gain bandwidth of 10.7% are obtained. INDEX TERMS Resonant cavity antenna, compact, high gain, non-periodic microstrip superstrate, hybrid parasitic ring.

“…It provides both linear and circular polarization. However, microstrip antenna has disadvantages such as low level gain, narrow bandwidth, low efficiency, and low directivity [3]. The circular polarization (CP) is a special case of elliptical polarization and it is realized when antenna configuration excites two equal amplitude, time and space orthogonal resonant modes [4].…”

This paper proposes a high gain microstrip antenna with circular polarization for LTE applications at a working frequency of 2300 MHz. Gain of antenna is optimized by using an array method with 4 elements arranged in plannar using feed line of 50 Ohm, 100 Ohm and 70.7 Ohm. The proposed antenna designed using FR-4 substrate with (Ɛr) = 4.3, substrate thickness (h) of 1.6 mm and loss tangent (tan δ) of 0.0265. Gain of antenna can be optimized by increasing the number of elements in the array of the antenna. Circular polarization can be obtained by cutting the edge of a rectangular patch antenna with an angle of 45 0 . From the simulation results obtained reflection coefficient value of -20.02 dB and VSWR of 1.22 at the working frequency of 2300 MHz. The gain of proposed microstrip antenna is 10.56 dB with an impedance bandwidth value of 714 MHz (1925( -2639. The proposed antenna obtained a circular polarization with axial ratio of 1.745 dB at working frequency of 2300 MHz. Array method with four elements increased the gain of antena until 45.07% compared to the single element antenna.
