Bandwidth Enhancement for Low Frequency Meander Line Antenna

Abstract

Abstract-A simple and effective method of bandwidth enhancement for the printed meander line antenna (MLA) is proposed. This approach is characterized by symmetrically printing two meandering sections on both sides of a dielectric substrate and connecting them via shorting pins at the bottom of meandering sections, which are connected to a capacitive stripe for impedance matching. The illustrative equivalent circuit and the corresponding principle of bandwidth enhancement of this double-layered MLA are presented. The measured results of these double-layered and single-layered MLAs manifest the validity of our design approach.

Meander bowtie Antenna for Wearable Application

“…Although there were variations between conventional bowtie and meandered bowtie, the results presented in Figure 5 show that the meander bowtie antenna able to cover the desired ISM frequency (2.45 GHz) with the return loss below than 10 dB. This is due to the effect of additional capacitance and inductance value between each mandering turns [17]. The antenna impedance matching can be improved using several techniques such as parallel matching stub, reactive network or impedance transformer.…”
