Abstract: Embodiments relate to systems and methods for a frequency reconfigurable filtenna system. Implementations incorporate a reconfigurable band-pass filter within the feeding line of an antenna structure. The combination of the filter and the antenna may be referred to as a “filtenna”. Implementations integrate both the band-pass filter and the antenna within the same substrate, permitting easier, more efficient and more compact integration in the transceiver hardware. Moreover, by using this configuration, the biasing of the switching elements are not present in the radiating plane of the antenna. This reduces the negative effect of the biasing lines on the antenna radiation performance, as we!! as provides a tunable filtered antenna radiation characteristic.
