The design has been suggested for applications in wireless communications (see Colburn, J.S. and Rahmat-Samii, Y., 1996). However, it cannot work well when it is placed close to a finite PEC ground plane due to its reverse image. Recently, the electromagnetic band-gap (EBG) surface, also referred to as photonic band-gap (PBG) surface, has attracted researchers' interest because it has a potential to build low profiled and high efficiency antennas (see Sievenpiper, D. et al., 1999; Zhan Li and Rahmat-Samii, Y., 2000). The square curl antenna over an EBG surface is investigated in depth. Compared to the conventional curl antenna, it has the attractive feature of low profile as well as circular polarization. The antenna height, ground plane size and band-gap effect are analyzed in detail by the finite difference time domain (FDTD) method. This low profiled CP antenna is suitable for GPS, LAN, satellite links and other wireless communication applications.","PeriodicalId":159827,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. 2001 Digest.

This method has three unique features. The first is the hybridization scheme that combines the FE and BI representations of the fields. Instead of following the standard hybridization scheme used in the frequency domain, we propose a novel scheme that preserves the sparsity of the finite element matrix and that yields solutions free of spurious modes associated with interior BI resonances. The second feature is the use of a fast algorithm, the multilevel plane-wave time-domain (PWTD) method, for evaluating the BI. Invoking this scheme greatly reduces the computational expense when an object of large electrical dimensions is considered. Third, the FE component of the solver employs curvilinear tetrahedral elements to precisely model the scatterer's geometry and higher-order vector basis functions to accurately represent the fields.","PeriodicalId":159827,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. 2001 Digest.

Antennas and Propagation, vol.41, no.8, 1993). The mutual coupling between a pair of shorted annular ring (SAR) RSW antennas was studied theoretically and experimentally (see Khayat, M.A. et al., IEEE Trans. Antennas and Propagation, vol.48, no.10, 2000). The study showed that the E-plane mutual coupling between RSW antennas fell off as 1//spl Delta//sup 3/ (for thin substrates), where /spl Delta/ is the center-to-center separation between the antennas. This is a much faster falloff than for conventional microstrip antennas, where the E-plane mutual coupling decays as 1//spl Delta/ (for thin substrates). The weak mutual coupling property makes a RSW array design very promising. The mutual coupling between RSW elements in an array with an arbitrary lattice angle /spl alpha/ is considered. Specifically, the mutual coupling in an equilateral triangular lattice (/spl alpha/=60/spl deg/) and a square lattice (/spl alpha/=90/spl deg/) are studied. Two feeding methods, E-plane feeding and a rotated feeding are considered and results are compared with those of a conventional circular microstrip array. The grating lobe issue is also studied for different lattice angles.","PeriodicalId":159827,"journal":{"name":"IEEE Antennas and Propagation Society International Symposium. 2001 Digest.
