Design and comparison of printed antennas using meander line technique

Abstract

The interest for compact antennas in wireless communication increase due to the portability and mobility of the communication devices. Generally, an antenna at low frequency exhibits in large physical size. This project investigates the design of an antenna at 400 MHz. The simulation of the antenna has been performed using CST MWS. Since medical applications are dealing with low frequency, it will lead to large size of antenna which brings a challenge for wireless personal area network (WPAN). It is well known that the antenna performance decreases (according to Chu’s equation) as the size of antenna decreases. Therefore, antenna miniaturization using Meander Line (ML) will be taking place to overcome the challenges. Thus, this paper presents a comparison between i) printed dipole antenna without meander line technique, ii) printed dipole with meander line technique and iii) printed monopole antenna with meander line technique. The results show that an estimation of reduction size by 50% can be achieved using Meander Line technique.

Low Profile Monopole Meander Line Antenna for WLAN Applications

“…The antenna ought to have a high gain in order to receive available energy, and it must also be efficient in order to reduce losses [2]. The antenna is used in a variety of wireless electronic devices of various sizes [3]. Due to the limited space available for antennas in modern communication devices, antenna designers strive for compact antenna designs that meet wireless standards' preferred bandwidths.…”

“…e main goal of slotting, slitting, shorting pin/plate, and lumped element techniques is to make the antenna effective length longer than its physical length [16][17][18]. However, the meandering technique ensures maxima use of the antenna space [19]. For example, authors in [9] used a meandering strip and shorting pin to achieve a compact antenna (36 × 15 mm 2 ) operating at 2.…”
