Traditionally, an infinite ground plane is used to represent the water surface for analysis of antennas installed on ships or otherwise situated over water. While this is sufficient for some scenarios, we have found the need for more accuracy in representing short-range propagation close to a water surface. In this paper, we generate randomized, realistic water surfaces and use these in CEM simulations.

To analyze the broadband scattering of the composite bodies of revolution (BORs), the marching-on-in-degree (MOD) scheme with volume-surface integral equation (VSIE) are proposed in this paper. In terms of the rotational symmetric property, only the transverse plane needs to be meshed in the dielectric parts, as the generatrix is divided into segements on the metallic surface. And then the RWG-like basis functions and the triangular function are used respectively. The weighted Laguerre polynomials are chosen as the temporal basis functions. A numerical simulation has been done to demonstrate the accuracy and efficiency of the proposed method.

Previously developed hybrid genetic programming with low-level optimizer software is used along with two novel building block designs (3D loop and coil utilizing Fourier series) to design low frequency artificial magnetic conductor (AMC) ground planes using only design specifications. The methodology used to create these building block designs in the existing GP software is described, and an AMC design example covering 225-450 MHz is given. The design has 72.9% bandwidth and a thickness of λ0/15.

Design of a sensor network system for maintaining safety in an industrial setting using energy harvesting interfaced with multiple antennas is given. The practical implementation, low interference, and high accuracy make this type of system ideal for industrial safety and automation applications. The sensor network system that operates at 5.8 GHz can be subject to modification based on communication bands in the area as well as accuracy needs.

This paper represents a high-gain, single resonance microstrip patch antenna which operates at 14.70 GHz. Measurement result of electric field phi-polarized gain is 10.72 dB. There is an alternative design with four rectangular slots at 19.60 GHz. This antenna has compact structure thereby achieving size benefits over previously published works in literature. As a reason of large slitted structure the antenna manufactured easily and works well at high frequencies with more than 10 dB gain.
