Abstract
A Frequency-tunable and slot-fed planar antenna is proposed. The antenna includes resonant patch, a first dielectric layer, a ground plane having a first slot for each linear polarization, a second dielectric layer and a transmission line having, for each first slot, an end strand extending beneath the first slot. The antenna is frequency tunable for each linear polarization through at least one variable capacitance element. The matching of the antenna varies, for each linear polarization, as a function of a bias voltage applied to the variable capacitance element(s). The antenna includes, for each linear polarization, at least one second slot extending along the first slot. The end strand of the transmission line extends between the first slot and second slots. The at least one second slot creates an additional resonance.
