“…(2) The distance from the margin of the cover to the same side margin of the window should be approximately half wavelength, thus the tangential E field of the cover margin and that in the window can be inphase. (3) The size of the open window should neither be too large nor too small, too small a window means small aperture size, but too large a window will lead that the cover can not get enough coupled energy from the slot.…”

A Novel cavity-backed slot antenna with high gain and broad-band is presented. A metal superstrate with a window is placed above the substrate to attain high-gain characteristics. Simulation and measurement results show that the proposed antenna achieves a high gain (>10dB) within the bandwidth from 2.30GHz to 2.50GHz, and -10dB return loss with a bandwidth of 200 MHz in the 2.40 GHz frequency band, while it still retains the broadband impedance characteristics.

“…Juntunen and Tsiboukis [2] introduced a simple correction procedure for reduction of the numerical dispersion in the two-dimensional (2-D) and three-dimensional (3-D) FDTD algorithm. Then Zhao [3] further presented an efficient approach to reduce numerical dispersion of 2-D ADI-FDTD method. The numerical dispersion relation along the axis direction is obtained by Zheng and Leung [4].…”

In this letter, a triple‐band Z‐like cavity‐backed slot antenna was designed, fabricated, and measured. A Z‐like slot is employed here to attain the triple‐band operation, whereas a metallic superstrate is placed above the Z‐like slot to achieve the high‐gain enhancement within the lower bandwidth at 2.45 GHz. The parametric studies of the proposed‐antenna are provided and mechanisms of triple‐band operation and gain enhancement within the lower bandwidth are also discussed. The measured‐results are in good agreements with simulated ones, which reach the bandwidth from 2.26 to 2.58 GHz, 5.15 to 5.28 GHz, and 5.68 to 5.88 GHz, respectively. Simulated‐ and measured‐gain results show that the proposed‐antenna reaches 11.59 dBi at 2.45 GHz, higher than 7 dBi at band of 5.25 GHz and 6.0 dBi at band of 5.85 GHz, respectively. © 2009 Wiley Periodicals, Inc.

“…One shortcoming of slot antennas is their bi-directional radiation characteristic which is alleviated by using a shallow cavity on one side of the slot. The performance of several cavity-backed aperture antennas has been investigated in the past [1][2][3][4]. With the recent trends in the design of compact communication systems, a demand has arisen for antennas which can be operated in multiple frequency bands.…”

This paper investigates the properties of probe fed cavitybacked fractal aperture antennas. The problem is formulated using the finite element-boundary integral (FE-BI) method in which the field inside the cavity is formulated using the finite element method, and the mesh is truncated at cavity aperture surface using the boundary integral method. Several dual-band cavity-backed fractal aperture antennas based on Sierpinski gasket, Sierpinski carpet, plus shape fractal and Minkowski fractal are investigated. The numerical results obtained from the FE-BI code have been validated with simulations on HFSS.
