This paper introduces a compact millimeter-wave tunable filtenna with defected ground-
plane structure (DGS) resonators for future fifth generation (5G) applications. An approach of …

Frequency reconfigurable dielectric resonator antennas (DRAs) are a type of antenna that
can adjust their operating frequency without physically changing their shape or size. DRAs …

In conventional communication systems, dedicated tunable circuit elements are used to
realize different functions and achieve performance metrics. For example, tuning the center …

In this article, a novel polarization reconfigurable antenna based on the Moiré effect is
proposed. The presented design exploits substantial changes in the overlapped Moiré …

This paper proposes a simple rectangular patch antenna for its operation in the S-band at
2.43 GHz frequency. The length and width of the antenna are increased gradually, and the …
