Perkembangan era digital ini tidak lepas juga pada televisi, di mana televisi mengalami perubahan dari analog ke digital yang tertuang pada peraturan kominfo. Penyiaran televisi digital di indonesia mengunakan setandar Digital Video Broadcasting – Second Generation Terestrial (DVB-T2) yang berkerja pada range frekuensi 478-694 MHz. Proses peralihan dari televisi analog ke digital akan membutuhkan antena yang sesuai, yang dapat menangkap sinyal tersebut. Antena mikrostrip memiliki kelebihan bentuknya yang compact dan mudah untuk difabrikasi, namun memiliki kelemahan di antaranya bandwith yang d

Abstract:
In this paper, a new class of broadband and low-loss transmission line called slotted rectangular waveguide (SRW) is proposed and analyzed. The proposed SRW consists of the rectangular waveguide and the inverted low-loss slotline, which can selectively suppress the higher-order mode (TE20 mode) and broaden the single dominant mode (TE10 mode) bandwidth in a rectangular waveguide (RW). The design principle and transmission characteristics of the SRW are illustrated and analyzed in this work. The transmission dominant mode bandwidth of the proposed SRW is analyzed and compared with the classic r

In this article, a Multiple-Input-Multiple-Output (MIMO) H-shape Dielectric Resonator Antenna (DRA) is designed and simulated at 2.6 GHz for 4G applications. The proposed structure consists of H-shape DRA ( =10) which is mounted on FR4 substrate ( =4.6), and feed by two different feeding mechanisms. First, microstrip with slot coupling as Port 1. Second, coaxial probe as Port 2. The electrical properties of the proposed MIMO H-shape DRA in term of return loss, bandwidth and gain are completely obtained by using CST Microwave Studio Suite Software.

Abstract:
Bandwidth characteristic enhancement of the antenna is engaging and challenging problems for antenna engineers. The design of the 639 MHz frequency of the low-profile inverted F antenna (IFA) on a finite conducting plane proposed and its characteristics are analyzed numerically. The IFA is typically a narrowband antenna, due to the bandwidth enhancement the antenna parameters are considered. When the size of the conducting plane is 115 mm by 230 mm, the return loss bandwidth (-10 dB) becomes 2.4 % and the gain becomes 6.58 dB. The results found that when the height of the antenna reduced the r
