Compact Open-Slot Antenna With Bandwidth Enhancement 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. Matching Slot Role in Bandwidth Enhancement of SIW Cavity cavity and a rectangular slot close to the feed point has been etched (to add extra resonance to enhance the bandwidth of the antenna in the desired frequency range). Tuning the rectangular slot improved the fractional bandwidth to 8%. A 7.9 dBi peak gain and a steady beam over the entire bandwidth … Slotted rectangular microstrip antenna for bandwidth A half-U-slot-cut and rectangular-slot-cut are used in rectangular microstrip antenna to increase gain and bandwidth of antenna[6].The reverse L-shaped slot is connected from bottom of rectangular

BANDWIDTH IMPROVED DESIGN OF SLOT ANTENNA C. R. Kuwar 1, D. B. Salunke 2, ... The parameters ‘W1’ and ‘L1’ are the width and length of the rectangular slot respectively. ‘H’ ... it is clearly indicated that the reference antenna bandwidth is modified by slot L2. The design is successfully implemented and it gives -10dB Very Small Dual Band-Notched Rectangular Slot Antenna With ... This antenna consists of a rectangular slot, a beveled rectangular patch, two S-shaped slits cut in the ground plane and an elliptical ring slot (ERS) etched in the patch. The corners of a simple rectangular patch are beveled to improve the impedance bandwidth, especially at the middle frequencies of the band.
If we can excite some reasonable fields in the slot (often called the aperture), we have a slot antenna. Figure 1. Rectangular Slot antenna with dimensions a and b. To gain an intuition about slot antennas, first we'll learn Babinet's principle (put into antenna terms by H. G. Booker in 1946). Research Article Novel Design of Microstrip Antenna with ...
