A Study of Techniques to Solve the Disparate Mesh Size Problem With an Application to Sinuous Antennas
… multipole method (FMM) to a particular wideband antenna, the sinuous antenna. The essence of the problem is that a triangular patch mesh containing a wide range in patch sizes produces an ill-conditioned method of moments impedance matrix. Since the FMM algorithm relies on iterative solvers to …

Electrically-Small Antenna Performance Enhancement for Near-Field Detuning Environments
… low-profile omnidirectional, electrically-small antennas has evolved from the design and construction of AM transmitter towers eighty years ago to current market demand for battery-powered personal communication devices. Electrically-small antenna theory developed with well-known approximations …

Development of Integrated "Chip-Scale" Active Antennas for Wireless Applications
… data networks (WLANs). Integrated microstrip antennas coupled directly to the RF electronics, offer potential advantages of low cost, reduced parasitics, simplified assembly and design flexibility compared to systems based on discrete antennas. However, the size of such antennas is governed by …

Manipulation of antenna-mode radar cross-section in patch antennas
The Radar Cross-Section (RCS) of an antenna has two main components: structural RCS and antenna-mode RCS. Structural RCS is due to the physical geometry of the antenna. The antenna-mode RCS component is due to load impedance mismatches and can be manipulated by changing the load impedance connected …
