Slot Antenna . Figure 1: The length of a slot determines the resonant frequency, the width of the slit determines the broad bandwidth of the slot radiator. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. Chapter 8 Slot Antennas - 电子创新网 a thin rectangular slot cut in a circular cylinder differs from that of a slot cut in a flat metal sheet because the distribution of electric currents is different for the two cases. In general, the slot antenna is not free to radiate on both sides of the surface on which it is cut because one side is either completely enclosed, e.g., the ...

Chapter 5 Impedance of Slot Antennas 5.1 Introduction that, due to the change in εr, the resonance frequency of the slot is now lowered to a resonance of about 5.7GHz. The thicknesses of the supporting substrates (layers 1, 2, 3 in Figure 5.1) are now adjusted to be nominally one quarter of a wavelength thick at 5.7GHz. The impedance of the slot is lower because the higher dielectric Dual Resonant Slot Antennas for Wireless Applications
