Radar Basics - Slot 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. However, the proposed antenna utilizes probe feeding that results in narrow Design of Asymmetric Slot Antenna with Meandered Narrow ... Design of Asymmetric Slot Antenna with Meandered Narrow Rectangular Slit for Dual Band Applications Raj Kumar1, *, Praveen V. Naidu2, and Vivek Kamble3 Abstract|A compact, coplanar waveguide (CPW) fed asymmetric slot antenna with dual operating bands is proposed. The slot is modifled rectangular in shape and asymmetrically cut in the ground plane.
