“…Antena yang cukup baik digunakan untuk keperluan tersebut adalah jenis antena log periodic dipole array (LPDA). Antena LPDA merupakan antenna jenis direksional dan sangat baik untuk semua aplikasi yang membutuhkan rentang frekuensi yang lebar Jurnal Nasional Teknik Elektro 31 disertai dengan penguatan yang wajar [3]. Selain itu jika jika antenna LPDA dibuat versi mikrostripnya, kelebihannya bertambah yaitu ukuran yang kecil, ringan, mudah dibuat, pola radiasi yang terarah [4].…”

Abstrak-Telah dilakukan rancang bangun antena mikrostrip log periodic dipole antenna (LPDA) yang akan digunakan sebagai alat ukur radiasi medan elektromagnetik pada base trransceiver station (BTS). Sebelum dijadikan alat ukur radiasi medan elektromagnetik BTS, karakteristik antena dilihat terlebih dahulu dari sisi return loss, dan pola radiasi yang dihasilkan. Desain antena LPDA menggunakan spesifikasi khusus dengan parameter τ = 0.88 dan σ = 0.12. Pembuatan antena secara mikrostrip dengan bahan dielektrik berupa FR4 sebagai substrat dan elemen antena berupa tembaga. Pengukuran return loss menggunakan network analyzer dan pola radiasi diukur di semi anechoic chamber 3 m di frekuensi operasi kerja BTS Indonesia (frekuensi 850,

“…Nowadays, the bandwidth often mixes the UHF-WLAN bands with the LTE bands [1][2][3]. Sometimes, the SHF-WLAN band may also be included [4][5][6]. For the configurations of the antennas, most of them involve the use of the meandered lines.…”

“…For the configurations of the antennas, most of them involve the use of the meandered lines. In [5,6], however, the log-periodic dipole arrays are adopted. As the lowest frequency is decreased to 690 MHz, it causes the main challenge to design the mobile antenna with an even limited space.…”

Abstract-An antenna designated mainly for cellular telephony purposes is presented. It covers one full band from 690 MHz to 2700 MHz with 6 dB return-loss criterion. The antenna is dimensioned 45 mm by 22.5 mm and is 0.8 mm in thickness. It is composed of a T-shaped monopole on the front-side and a meandered line on the back-side of an FR4 substrate. The T-shaped monopole is responsible for the high-band resonances. The meandered line is divided into three parts: the first part functions as a distributed inductor; the second part plays the role as a low-band resonator, and the third part is a tuning element. The distributed inductor and the low-band resonator are both folded strips in configuration, but with different spacing. The tuning element is used to improve the match so that one full band operation can be realized. To clarify the operational mechanism, modes separately generated from each part are analyzed and compared to modes of the proposed antenna.

A novel planar printed log-periodic dipole array (LPDA) antenna fed by tapered microstrip line (MSL) to double sided parallel strip line (DSPSL) is proposed in this paper. The proposed antenna adopts MSL feeding approach from backside. Using this feeding technique makes the printed LPDA antenna easier to be integrated into radio frequency (RF) circuits. In this paper, four layers are used to construct the antenna. The four layers of the printed LPDA antenna are printed on three thin dielectric substrates which are integrated together. To validate this approach, a printed LPDA antenna is simulated and fabricated for operating in the S and C bands (2.5-6 GHz). The antenna showed a good result over the whole frequency range with 2 : 1 VSWR, an average gain of 6.5 dB, and stable radiation patterns. The measured results are in very good agreement with simulations.
