Polarization Reconfigurable Eccentric Annular Ring Slot ... Abstract: A microstrip-fed reconfigurable eccentric annular ring slot (EARS) antenna with switchable polarization is proposed. To generate orthogonal circular polarization (CP) radiations, two identical perturbation slots (PSs) are loaded below the eccentric ring-shaped slot.

A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. antenna | 论文

A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has A Broadband Multi-layer Dual-polarization Slot Antenna ... Suh Y H, Park I.

Figure 1 shows the geometry of the proposed antenna. The cylindrical DR has a radius of a = 5mm, a height of d = 12mm and a relative permittivity "d = 10:2. The DR is positioned on top of the substrate. An annular slot and an L-shaped microstrip ...
