A broadband eccentric annular slot antenna

A Compact Annular Ring Microstrip Antenna for WSN Applications 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

Abstract: A wideband circularly polarized (CP) annular-ring patch antenna with two proximity-coupled L-probe feeds orientated to have phases of 0 deg and 90 deg, using a broadband 90 deg hybrid feed, is proposed. It is found that the current distribution for CP operation can be improved by cutting a smaller concentric circular slot on the original larger circular patch to form an annular-ring ...

Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. A Compact Annular Ring Microstrip Antenna for WSN 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. Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.

BROADBAND CIRCULARLY POLARIZED DIELECTRIC RESONATOR ANTENNA ... the work in [18], a broadband CP cylindrical DRA with annular slot excitation is investigated here. 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 ...
