Pada penelitian ini dilakukan perancangan antena mikrostrip dengan menggunakan metode split ring resonator (SRR) untuk aplikasi pada frekuensi L-Band. Antena ini mempunyai dimensi substrat 90 mm x 50 mm dengan panjang patch 60 mm dan lebar patch 44 mm. Desain antena menggunakan material FR4-Epoxy dengan spesifikasi konstanta dielektrik 4,6 dengan ketebalan 1,6 mm dan dielectric loss tangent 0,02. Pada penelitian ini, parameter yang mengalami perubahan signifikan adalah lebar patch SRR, gap SRR, dan posisi SRR pada ground plane. Desain patch SRR dengan nilai sepertiga panjang gelombang pada frekuensi 1,5 GHz memenuhi karakteristik dari frekuensi L-Band. Berdasarkan hasil simulasi, antena menghasilkan bandwidth (< -10 dB) sebesar 1,2466 GHz dengan rentang frekuensi 988,25 MHz sampai 2,2349 GHz. Nilai return loss simulasi adalah -36,89 dB. Pada rentang 1 GHz sampai 2 GHz, gain tertinggi berada pada frekuensi 2 GHz dengan nilai 3,5 dBi. Sedangkan gain terendah adalah 1,21 dBi, yaitu pada frekuensi 1,050 GHz. Secara keseluruhan, desain antena ini telah mencapai performa kinerja yang lebih baik melalui modifikasi pada patch SRR.

Working Frequency

Digital television technology has more benefit than analog television, for example several TV channel may included in one frequency channel. The changing from analog to digital televisions system require more innovative antenna parameter such as working frequency, bandwidth, return loss, VSWR, and gain. In other hand, the size of the antenna must be minimalized, so it can be integrated inside digital television. This research used metamaterial element of Complementary Split Ring Resonator (CSSR) method with negative permittivity that manufactured in the patch and Double Pole Ground Plane in the ground side. The antenna ad 478-694 operating frequency. Antenna design and simulation using CST (Computer Simulation Technology) Microwave Studio 2012. The result show that return-loss value < -10 dB, and VSWR = 2 at 478-625 MHz range of frequency. Te value of gain is 3.27 dBi, it has 147 MHz bandwidth, and omnidirectional radiation pattern.

Complementary Split Ring Resonator

Phase shifters are indispensable microwave components. In this paper, a dual-frequency, passive, analog, and reciprocal phase shifter is proposed, deploying the phase-delay characteristics of complementary split-ring resonator (CSRR). A transmission line is loaded with a pair of CSRR in the ground plane and the phase variations are compared with an ideal transmission line. The proposed phase shifter operates in the industrial, scientific and medical (ISM) and wireless local area network (WLAN) bands, providing a phase of 180° at 2.4 GHz and 90° at 5.4 GHz for beam steering applications.

A multi-input multi-output (MIMO) antenna with improved isolation using an interdigital split ring resonator (SRR) is proposed. The necessary impedance bandwidth is obtained by utilizing the coupling between the meander strip and an invertedLstrip. Using interdigital SRR, a negative permeability was generated, while achieving improved isolation between the two radiating elements. The fabricated antenna satisfies the 10 dB return loss in the long-term evolution (LTE) band 40 from 2.3 GHz to 2.4 GHz. The measured peak gains of the two elements were 2.0 dBi and 1.3 dBi. The measured envelope correlation coefficient was less than 0.16 over the frequency band of interest.

Abstract This paper presents the design and simulation of patch antenna loaded with metamaterial called Complementary Split Ring Resonator (CSRR) with increased gain and bandwidth suitable for wireless applications such as satellite, TV and radar applications. FR4 substrate with dielectric constant (εr ) of 4.4 is used. The radiating patch consists of CSRR structure fed by microstrip line to achieve triple(C, X, Ku ) band characteristics. The proposed antenna is designed and simulated using Ansys High Frequency Structural Simulator (HFSS). The proposed antenna with 4 rings having a resonant frequency of 7.662, 9.8510, 10.9455, 11.8410, 12.7365 and 13.7315GHz and the bandwidth of 230, 1090, 640, 580, 620 and 2000MHz respectively. The proposed antenna with 6 rings also having a resonant frequency of 7.7615, 9.9525, 11.0450, 11.9405 and13.7315GHz and bandwidth of 160, 1130, 490, 1360 and 1480MHz are achieved. The proposed antenna is analyzed in terms of return loss, VSWR, gain and bandwidth. The electric field and surface current distribution were observed for the proposed antenna having 6 rings.
