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. antenna | 论文 Lei Ge, Chow-Yen-Desmond Sim, Chuan-Wei Lin and Ting-An Chen, "Eccentric Annular Slot Patch Antenna with Frequency Agility for UHF RFID Reader Applications," International Journal of RF and Microwave Computer-Aided Engineering, vol. 27, no.2, pp. 1-9, Oct. 2016.

A Compact Annular Ring Microstrip Antenna for WSN Applications Introduction. The patch antenna could be installed only in a thin annular slot on the top of the installation base whose inner radius was greater than 5 mm and outer radius less than 20 mm. Therefore, the size of the designed antenna must comply with the requirements of the limited mounting space. Polarization Reconfigurable Eccentric Annular Ring Slot ...

The Q134 antenna capitalizes on Harris’ proven annular-slot technology providing a 3.7:1 operating bandwidth, which exceeds the useful bandwidth of most blades and other exposed apertures. In addition to the broad operating bandwidth, the Q134 also
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 ...

Simulated magnetic current distributions of Antenna 4 ... 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).
