Abstract:

A low profile multiple linear-polarization ( multi-LP) reconfigurable cavity-backed magneto-electric (ME) dipole antenna is developed in this letter. The magnetic-dipole (M-dipole) is realized by a TM

$_{020}$

-mode slotted substrate-integrated cavity, and the electric-dipole (E-dipole) is the printed microstrip dipole coupled above the slotted cavity. By introducing a rotationally symmetrical configuration of ME dipoles with switchable feeding networks, we have realized the reconfigurable multi-LP states for the cavity-based ME-dipole antenna. As a benefit of the dipole-loaded slotted cavity configuration, the antenna profile is only

$0.09\lambda _{0}$

, which is much lower than conventional reconfigurable ME dipole antennas. The developed antenna is capable of switching eight LP states at a

$22.5^{\circ }$

interval in real time by electronically controlling PIN diodes loaded on the slotted cavity. Measured results agree well with the simulated ones. At the center frequency of 5.04 GHz, a measured maximum gain of 4.46 dB is obtained for all polarization states. It is the first time to achieve simultaneous multi-LPs and low profile for ME-dipole antenna.
