Slot antenna Slot antenna with FSS (simulated).A second order, band pass frequency selective surface with large bandwidth combined with a wideband slot an-tenna has been studied and demonstrated successfully. Slotted UWB Antenna for Bandwidth and Gain Enhancement Capability of operating over wide frequency bands and good radiation characteristics lead to choosing a rectangular radiation patch as a basic structure of the slot antenna. Modifications have been applied to the radiation patch to manage the current distribution in order to achieve a wide bandwidth. Implementation of rectangular slit-inserted ultra-wideband… In this paper, a tapered slot antenna is designed and proposed. The antenna has a 3 dB beam width, high gain, and directive characteristics, which are appropriate for reducing the area of the antenna and for location recognition. The bandwidth was improved by inserting rectangular slits in the radiator of... Enhanced bandwidth slotted microstrip patch antenna
Antenna designs were achieved for wideband operation by the use of a coplanar patch-slot antenna, fed by a coplanar waveguide. This design is easily tuned to operate at 2.45 and 5.75 GHz, with wide bandwidth for wireless systems. The oper- ating frequency is controlled by modifying the patch dimensions. How do I change the antenna structure to improve bandwidth? With decrease in dielectric constant both the resonant frequency as well as the bandwidth increases. so try using a subtsrate with low dielectric constant. OR. feed the antenna using aperture slot coupling. aperture slot coupling has the advantage of providing increased bandwidth compared to any other feeding mechanisms. OR Rectangular Microstrip Antenna on Ridge Ground Plane to ...
