Slot Antenna - IDC-Online Zd = impedance of its dual antenna . η = intrinsic impedance of free space. It follows for Zs = 485 Ω. The band width of a narrow rectangular slot is equal to that of the related dipole, and is equal to half the bandwidth of a cylindrical dipole with a diameter equal to the slot width. Figure 2 shows slot antennas different from the rectangular shape that increasing the bandwidth of the slot antenna. Figure 2: Various broadband slot antenna.

Babinet's Principle. One may view a slot antenna to be physically complementary to a strip dipole antenna consisting of a metal strip of the same. shape and size as that of the slot. The complementary strip dipole is to be excited by a voltage gap, breaking across the strip at the same position where the slot antenna is excited. If the slot antenna is superimposed on its complementary dipole ...
Slot Antenna The dual of a slot antenna would be if the conductive material and air were interchanged - that is, the slot antenna became a metal slab in space. An example of dual antennas is shown in Figure 2: Figure 2. Dual antennas - (left) the slot antenna, (right) the dipole antenna. Note that a voltage source is applied across the short end of the slot YO3DAC - Printed and Microstrip Antennas - qsl.net - Basic Printed Slot Antennas with Feed Structures - Comparison of Microstrip Patch and Slot Antennas. 10-dBi Dual-fed Slotted Planar Antenna; 14-dBi Gain P2P Antenna; Aperture Coupled Microstrip Antenna; Bent Wideband Printed Antenna for 3GHz to 5GHz; Broadband PI-shaped Monopole Antenna for 2.4GHz Dual-band blade antenna - Wikipedia One way to create a dual band blade antenna is to create a slot in a blade antenna that is less than or on the order of so that the lower frequency does not 'see' the slot (it is a rule of thumb that the perturbation created by a discontinuity less than on a structure is negligible).
