3-17 Basic Slot Antenna and Its Complementary Dipole The slot antenna consists of a radiator formed by cutting a narrow slot in a large metal surface. Such an antenna is shown in figure 3-18. The slot length is a half wavelength at the desired frequency and the width is a small fraction of a wavelength. Chapter 8 Slot Antennas - 电子创新网

The slot antenna is assumed to be equivalent to a magnetic dipole with a prescribed magnetic current distribution. It is concluded that the field patterns of the slot are greatly affect by the presence of the ionized medium.

RADIATION PATTERNS . The radiation pattern is a graphical depiction of the relative field strength transmitted from or received by the antenna. Antenna radiation patterns are taken at one frequency, one polarization, and one plane cut. The patterns are usually presented in polar or rectilinear form with a dB strength scale. The Basics of Patch Antennas, Updated - Orban Microwave Radiation Pattern A patch antenna radiates power in certain directions and we say that the antenna has directivity (usually expressed in dBi). If the antenna had a 100% radiation efficiency, all directivity would be converted to gain. Typical half wave patches have efficiencies well above 90%. The directivity of a patch can be estimated quite ... Slot Microstrip Antenna for 2.4GHz RFID Reader Application E. Radiation Pattern In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source. This antenna shows a strong electric field at the top of the antenna where the slot is present. This High Gain Vivaldi Antenna for Radar and Microwave Imaging ...
