“…The antenna volume, which is expressed in electrical units, relative to the reported design frequency, is given. Finally, the reference for From this summary table, we note that small volume antennas can achieve high-impedance bandwidth, but at the cost of low peak gain (e.g., [6], [13]). Some of the designs with the highest gain had the lowest reported bandwidth (e.g., [16], [19], [20]).…”

We present two designs that improve the gain and cross-polarization performance of the waveguide-fed short backfire (SBF) antenna by introducing a choke (SBF-2) and by loading the cavity with a metallic ring feature (SBF-2-Ring). A series of parametric simulation studies on antenna dimensions provides information on how to improve the antenna gain and cross-polarization performance while simultaneously extending the impedance bandwidth. For SBF-2, the peak gain was 16.6 dBi, the minimum cross-polarization ratio was −23.8 dB, and the maximum impedance bandwidth was 27.3%, with a gain bandwidth of 19.2%. For SBF-2-Ring, the peak gain was 15.8 dBi, the minimum cross-polarization ratio was −29.1 dB, and the maximum impedance bandwidth was 43.5%, with a gain bandwidth of 31.8%. The concepts were verified by designing, fabricating, and testing two prototypes in the microwave C-band. Excellent agreement between simulation and measurement was achieved. The measured gain for SBF-2-Ring was >14 dBi for 4.7-6.2 GHz and the worst case cross polarization in the diagonal plane was <−22 dB for 5.3-5.8 GHz. Cross-polarization in the principal planes has significantly greater bandwidth and the worst case analysis is presented to give limitations on the performance.

This article present a compact proposed patch antenna for impedance matched for simple two horizontal slot is placed in a active patch with a via hole in sandwiched between radiated patch and bottom plane of an microstrip patch antenna for a band of 4 to 12Ghz application. The planned antenna is synthesized by using glass reinforced epoxy laminated material (FR4) and electromagnetic 3D view (IE3D) software. The software based design is suitable for a band of 3.3//5.5 Wi-Max and 5.3/5.8 WLAN frequency band. It is also suitable for satellite application The ground and exciting patch is separated by 1.5mm thickness. The proposed antenna parameter is design for 10Ghz..For such design the achieved Bandwidth for an antenna is 53 % at a VSWR<2, acceptable return loss (S11) = - 22.5dB, and the directivity of an antenna is 6 dBi. The antenna is appropriate for an application of X band. The designs of an antenna and its result have been discussed in detail.
