- Abstract
A circularly polarized cavity-backed crossed loop antenna is proposed in this article. The optimized overall dimensions of the antenna are 1.13λo in diameter and 0.267λo in height (λo is the free-space wavelength at the center frequency), and the circumference of one loop is 1.1λo. Measurements show that the proposed antenna features an 81% impedance bandwidth for SWR ≤2, a 40% bandwidth for axial ratio ≤3 dB, an average gain of 10 dBi, and stable radiation patterns over the whole band from 1.42 to 2.13 GHz. © 2009 Wiley Periodicals, Inc.
