In the antenna geometry, employing one arc-shaped, two inverted-L grounded strips and a C shaped gap on the patch, improved 3 dB ARBW and impedance bandwidth noticeably in compare with previous works.
In addition, by properly inserting an F-shaped stub on the wide-slot ground plane, the antenna can reach a relatively wide 3 dB ARBW as large as 19% (3.
It can be seen in Figure 5 that the ARBW of the antenna increased to 4.
s], an UWB CPSS antenna will be obtained which its ARBW is 13.
IV) are presented in Figure 16 and in addition, return loss and 3dB ARBW of the Ant.
2], yet the CP band have a 3dB ARBW of as large as 28.
Both antennas possess a 3-dB ARBW of more than 25% with the corresponding 3-dB AR band completely enclosed in the associated VSWR [less than or equal to] 2 impedance band.
area (MHz) (MHz) ARBW (%) (mm x mm), (mm x mm), ([[lambda].
The remaining ones are regarded as wideband CP antennas, whose 3-dB ARBWs are all larger than 25% with respect to the center frequencies of their 3-dB axial-ratio (AR) bands (or alternatively called CP bands for short).
Although the 3-dB ARBWs of these slot antennas are as large as 31% to 45%, their normalized antenna areas are comparatively large (larger than 0.
For comparison with those antennas in terms of antenna gains and ARBWs, the antenna design procedures to be developed in this study will also use an S-band CP PSSA as an example.
