TLDR
In this article, an ultra-wide tuning range filtering antenna is proposed in which the frequency tuning range is from 200 MHz to 1.8 GHz which covers from P to L bands by a varactor and two singlepole-doube-throw switches.Abstract:
An ultra-wide tuning range filtering antenna is proposed in this paper. The frequency tuning range is from 200 MHz to 1.8 GHz which covers from P to L bands by a varactor and two single-pole-doube-throw switches. The switches controls two groups of inductors which corresponding to two frequency tuning range. The filtering antenna has high selectivity and low insertion loss and very wide frequency tuning range.read more

A Varactor-Based Reconfigurable Filtenna
TL;DR: This letter details a new reconfiguration technique for implementing frequency-tunable bandpass filters by changing the filter total capacitance via an integrated varactor within its structure, which allows the tuning of the antenna operating frequency without incorporating active components and biasing lines on the antenna radiating surface.
