Miniaturized Meander-Line Dipole Antenna For Short-Range Wireless Communication Networks

Abstract

This paper presents the design and performance analysis of a planar, miniaturized meander-line dipole antenna designed for short-range wireless communication links. The proposed compact antenna has a size of 0.08λo × 0.03λo (at fo = 288 MHz) and designed on a sapphire substrate with optimized dimensions of 80.75 × 31.3 × 1.5 mm 3 . This electrically small antenna design is comprised of symmetric C-shaped resonators with meandered lines and gaps to perform frequency tuning. Simulated results show that the antenna can be effectively tuned to 288 MHz, 298 MHz and 310 MHz by applying structural reconfigurations. The radiation pattern in all the suggested frequency bands is perfectly omni-directional. The proposed antenna due to highly compact size is a potential candidate for the short-range wireless networks.
