Printed Wide-Slot Antenna Design with Bandwidth and Gain
Radar Basics - Slot Antennas Slot Antenna. The feeding of the slot antenna can be done with ordinary two-wire line. The impedance is dependent on the feeding point, as in a dipole. The value of 485 ω applies only to a feeding point at the center. A shift of the feed point from the center to the edge steadily decreases the impedance. ENHANCEMENT OF BANDWIDTH OF RECTANGULAR PATCH … The VSWR, input impedance‚ and S11 performance are used for the analysis of the different configurations. The simulated results for square slots antenna structure give bandwidth of 311 MHZ. Feed point on the patch that gives a good match of 50 ohm. Antenna Theory - Slot - Tutorials Point These slot antennas can be formed by simply making a cut on the surface, where they are mounted on. Frequency Range. The frequency range used for the application of Slot antenna is 300 MHz to 30 GHz. It works in UHF and SHF frequency ranges. Construction & Working of Slot Antennas. The use of slot antennas is well understood through its working principle. Chapter 8 Slot Antennas - eetrend.com

Effect of antenna size on gain, bandwidth, and efficiency If higher gain is desired, the antenna must necessarily be a narrow-band device. In fact, the input impedance becomes frequency sensitive so rapidly that, for large antennas, no significant increase in gain over that of the uniformly illuminated aperture is possible.
