one, the gain of the proposed antenna improved about. 1.4 dB. Moreover, the .... slots at the top, the -10 dB bandwidth falls within 3.85 and. 16.15 GHz, which is ... Improved Bandwidth and Gain in Ultra-wideband Staircase Antipodal ... Nov 1, 2018 ... improve the bandwidth of the proposed antenna which is ..... Ultra-wideband planar tapered slot antenna for use in a microwave imaging ... Gain and Bandwidth Enhancement of Ferrite-Loaded CBS Antenna ...

Aug 18, 2011 · Abstract: A compact open-slot antenna for bandwidth enhancement is presented. Multiple resonances are generated by using an asymmetrical rectangular patch with the U-shaped open-slot structure. Two bevels are cut on the patch to improve the impedance matching.

How can I increase the bandwidth of a microstrip patch ... I have designed a microstrip patch antenna in HFSS at 28 GHz, its bandwidth is almost 1.5 GHz. ... Introduction of slots increase the BW about 30%. ... How can I improve the bandwidth of ... A symmetric multi slot patch antenna with improved bandwidth and... This technology demands for antennas with wide bandwidth and good isolation characteristics. There are various techniques proposed for improving the bandwidth of microstrip antennas. In [1], authors achieved considerable amount of bandwidth by employing slots and annular ring in the ground plane.

bandwidth [6], and V-slots corner notch loaded microstrip patch antenna employed 51% bandwidth [7]. Further, several other radiating structures have beenspecified beam widths. 4. Conclusion A broadband patch antenna with improved bandwidth has been discussed and presented successfully.

A rectangular slot antenna with improved bandwidth ... A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna. A rectangular slot antenna with improved bandwidth

Pod-Mounted Omnidirectional Traveling-Wave Antenna with High…

improve the gain and bandwidth of a slot antenna such as changing the feed dimensions, introducing a reflector [2]. Usually, loop antenna and slot antenna are the two classes of horizontally polarized antennas. In [4], a horizontally polarized Omni-directional loop antenna shows a desirable

A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna.

tuned over a 10% bandwidth. The bandwidth was increased to 45% when mechanical tuning was used by varying the feed-line length. Dipole tunable antennas ... CIRCULARLY POLARIZED SLOTTED APERTURE ANTENNA WITH ... are attained by placing open end slot at the lower side of the antenna. The proposed ... Axial ratio bandwidth can be improved by using different techniques. By.
