The contrawound toroidal helix antenna with constant current is examined; it has an omnidirectional pattern in the toroid plane. Radiation resistance is deri¨ed for the dipole mode, and results are ¨alidated by moment-method calculations. The radiation Qs of these antennas are greater than one milli

Abstract
A printed square slot loop antenna capable of radiating slant 45βdegree polarized signals over a wideband is presented. A radial wideband stub feeds the square slot loop at the diagonal and the antenna exhibits an impedance and radiation bandwidth of more than octaveband (1.7 to 3.5 GHz).

## Abstract A new broadband circularly polarized (CP) square slot antenna with coplanar waveguide fed is proposed. Two symmetrical Eβshaped slits embedded in opposite corners of ground plane are designed to obtain an excellent CP bandwidth. Simulated results show that the broadband performance is f
## Abstract In this article, a new design of a broadband dual circularly polarized square slot antenna loaded with metallic strips is presented. The proposed dual circular polarization (CP) radiations are achieved by loading the square slot with a Tβshaped strip and two microstrip Tβjunctions. The
