Abstract
In this paper, low-profile frequency reconfigurable patch antennas for cognitive radio applications are proposed on the ultra-wideband (UWB) frequency range. The methodology of the proposed antennas is described in this paper, and is achievable by controlling the electrical length of the antenna. additionally, miniaturized patch antennas are achieved by using shorting post technique and partial ground plane. The substrate used in the proposed antennas is the Rogers duroid 6010 with a dielectric constant of 10.2 and thickness of 0.635 mm. The presented antennas are designed and simulated using High-Frequency Structure Simulator (HFSS). The advantage of the proposed antenna designs is the compact size 8 mm × 8 mm (and smaller). The proposed antennas are designed, analyzed, and compared to a conventional microstrip patch antenna, and the total area size reduction is about 89% to meet the size requirements of wireless miniaturized systems and cognitive radio applications.
