A new patch antenna is analysed which provides dual-frequency operation by means of two narrow slots close to the patch radiating edges. The two modes of operations show similar radiating properties. The ratio between the two frequencies can be well controlled within a range varying from 1.6 to 2, by using simple semi-empirical formulas derived from a physical model and tested by using a ...

In my previous tutorial on hfss, I try to simulate a simple model of microstrip patch antenna with the wide range of operating frequency or broadband antenna.In this video, we are designing an antenna by cutting a U-slot in ...
Whip antenna - Wikipedia The whip antenna is a monopole antenna, and like a vertical dipole has an omnidirectional radiation pattern, radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated power falling off with elevation angle to zero on the antenna's axis.Whip antennas 1/4 wavelength long or less (the most common type) have a single main lobe, with field Frances Harackiewicz | Center for Embedded Systems | SIU
This compact planar antenna supports TM01 and TM10 modes on the patch structure due to the introduction of slots, resulting in dual-band operation. The ratio ...
For dual frequency operation, four slots are etched near edges of the patch and a crossed slot etched in the center for generating circular polarization. In order to reducing the frequency ratio of two frequency bands of the antenna, the patch is loaded by four short circuit microstrip stubs.
