The slot structure of the proposed antenna is with a circular slot structure. A smaller annular conducting ring with thickness w has been embedded in the slot structure.This shows flexibility in designing dual frequency antennas with the desired resonant frequencies.
Design of Integrated Triple Band-notched for Ultra ... B. Design and Theoretical Consideration of Slot This design procedure for overlapping U-shaped slot on patch antenna for antenna 2 is given in Fig. 2, by determining operation frequency ( B 4 and the lower and upper frequency bounds of the bandwidth as B ß â ê and Û Ü Ú Û, respectively, as follows: i. operation frequency, 4 = 7 GHz ii. Chapter 8 Slot Antennas - 电子创新网 because one side is either completely enclosed, e.g., the slotted cylinder antenna, or it is desired that the radiation on one side be minimized. In these cases, the influence of the enclosed cavity region on the excitation and impedance of the slot antenna is significant to the antenna design. 8.2 SLOTTED-WAVEGUIDE ANTENNAS Wideband Bow-Tie Slot Antennas with Tapered Tuning Stubs (CPW) is investigated. The design was realized using a tapered metal stub introduced in the middle of the bow-tie slot. The modified structure shows wider bandwidth over the conventional bow-tie slot antenna. Parametric study of this new antenna results in a design procedure that helps design this class of antennas Compact Two-Layer Slot Array Antenna with SIW for 60GHz ...

within the entire UWB. The design of a printed wide-slot antenna with a rotated slot is pre‐ sented in [20]. The impedance bandwidth of the antenna varies with the rotation angle of the slot and can maintain 50.2% with suitable angle. More recently, the design of a printed wide-slot antenna for wideband applications is proposed in [21].
