Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. Slot Antenna - IDC 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. Compact Rectangular Slot Patch Antenna for Dual Frequency ... This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12.

The design graphs are then used to compute the dimensions of a rectangular patch and feed network for a dual-frequency antenna for use at 1.9 and 2.4 GHz. For the feed network, two transmission lines are used to connect the two edge feeds to an open circuit stub to match the antenna at the two frequencies.

Dual-band slot loaded antennas have been studied and developed in various geometries. In [29], a dual-band slot-loaded rectangular patch antenna is presented. Two narrow slots have been inserted close to radiating edges to exhibit the multiband properties. The circular TC243 A Compact Wide slot antenna with dual band-notch ... ground plane [8]. However, several narrow bandwidth systems have been used for a long time, such as WLAN (5-6GHz) and X-band (7.7-8.5GHz). Therefore, plenty of UWB antennas with band notch antennas have been proposed for reducing the potential interference between UWB and narrow band A Compact Wide slot antenna with dual band- Design Narrow Slot Antenna for Dual Frequency - PIERS
In recent years, some papers were reported for Dual/triple band operation by using single/double U slot in the microstrip antenna. It is seen that the applications which require dual frequency operation with small frequency ratio were designed by using the U slot in a wideband micro strip antenna [9]. Micro strip antennas
To gain an intuition about slot antennas, first we'll learn Babinet's principle (put into antenna terms by H. G. Booker in 1946). This principle relates the radiated fields and impedance of an aperture or slot antenna to that of the field of its dual antenna. The dual of a slot antenna would be if the conductive material and air were ... CIRCULAR MICROSTRIP SLOT ANTENNA FOR DUAL- FREQUENCY RFID ... favorable to design a single antenna which operates on both frequency bands. A variety of dual-band slot loaded antennas have been reported in [26{28]. The dual-frequency characteristics have been demonstrated owing to a pair of slot is placed close to the radiating edges.
