Abstract EN
This paper presents a cross-type network design with a novel reconfigurable functionality to realize a tunable multiband antenna.
By attaching a reconfigurable network at the feeding port of a broadband antenna, multi-input impedance adjustment enables the production of multimatching operating bands.
Each band can be independently controlled by a single component with a considerably wide tuning range and high selectivity.
The experiments in this study involved using an ultra-wideband (UWB) antenna connected to the proposed cross-type network.
The tunable antenna operates in a dual band of f L (1.39 to 2.34 GHz) and f H (2.1 to 3.6 GHz) with tunable frequency ratios of 168% and 132%, respectively.
The average bandwidths at f L and f H are approximately 50 MHz and 148 MHz, respectively, implying narrowband operation.
The measured radiation pattern revealed that the tunable antenna exhibits a nearly omnidirectional radiation pattern at both 1.8 and 3.5 GHz.
The network circuit architecture can be extended to the multiband function type by adopting this matching approach.
The amount of shunt matches determines the number of operation bands.
