Wideband RCS Reduction of a Slot Array Antenna Using ... It is placed on the surface of the slot array antenna. The characteristics and mechanism of the RCS reduction are analyzed. Simulated and experimental results show that the monostatic RCS reduction band of the antenna with PCM ranges between 6.0 and 18.0 GHz for normally impinging both x- and y-polarized waves. Circularly polarized D‐shaped slot antenna for wireless ... To match the feed impedance with the antenna impedance, slots of various shapes are used. In the proposed antenna, semicircular arc‐shaped slot of radius (R g) is used in the ground. Slot antenna is advantageous over patch antenna as it provide greater bandwidth due to bidirectional radiation as in antenna2 structure.

A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner … Quad antenna - Wikipedia A quad antenna is a type of directional wire radio antenna used on the HF and VHF bands. Like a Yagi–Uda antenna ("Yagi"), a quad consists of a driven element and parasitic elements; however in a quad, each of these elements takes the form … Leaky wave antenna - Wikipedia Leaky-Wave Antenna (LWA) belong to the more general class of Traveling wave antenna, that use a traveling wave on a guiding structure as the main radiating mechanism.

B. Radiation Mechanism of Slot Antenna According to Babinet’s principle [3] a slot cut on a perfect electric conductor (PEC) can be treated as ac complementary dipole as shown in Fig.2. A typical radiation pattern and return loss for slot antenna is shown in Fig.3 and 4 respectively. It is Prof. Girish Kumar - nptel.ac.in
