Summary:
Handheld radios technologies compose one of the most rapidly growing industrial markets today. Moreover, the handheld radio, which is also called as a ‘walkie-talkie’ has been vastly used across sectors such as business, military, public safety etc. Naturally, these applications require antennas, and typically the types of the antenna that are more popularly used are such as helical antennas or dipoles. Due to the possible large miniaturization factor provided by the Meander Line Antenna (MLA), this work is an effort to investigate and determine the suitability of this design and miniaturization technique as an alternatives to dipoles and helical antennas. Moreover, it is also known that even though a higher dielectric constant (εr) may be inefficient in its radiation properties, implementing the antenna on a thin slab with high εr will most certainly produce a miniaturized antenna. In this project, the meander line technique has been applied to design a Meander-on-Slab (MoS) antenna to significantly reduce the physical size of a two-way radio antenna [1 ? 4]. The design of the MoS, which has small dimension, is implemented on several ceramic materials with different er, such as a Barium Strontium Titanate (BST), Rogers RO4003C and FR-4. Finally, results comparison between simulated MoS will be presented in order to determine its suitability for potential fabrication and commercialization.
