A Wideband Compact Quasi-Yagi Antenna with U-shaped Slots on The Ground Plane

A high‐gain quasi‐Yagi antenna using nested metaresonator structures

“…2,3 General characteristics of the quasi-Yagi antennas can be controlled by modifying the main elements such as the driver, ground, and director of the antenna. [4][5][6][7][8][9][10][11][12][13][14][15][16][17] Apart from forming an array, [18][19][20] quasi-Yagi antenna gain is conventionally enhanced by adding additional director elements. [21][22][23] Other gain enhancement methods typically involve modifying the director element of the quasi-Yagi antenna.…”

“…Among many, quasi‐Yagi antennas, in particular, have grown in popularity due to their desirable features such as high gain, large bandwidth, end‐fire radiation, and compatibility with planar circuitry 2,3 . General characteristics of the quasi‐Yagi antennas can be controlled by modifying the main elements such as the driver, ground, and director of the antenna 4–17 . Apart from forming an array, 18–20 quasi‐Yagi antenna gain is conventionally enhanced by adding additional director elements 21–23 .…”

A multiband quasi‐Yagi antenna using stepped driver and slotted ground for 2.4/3.5/5.2 GHz bands applications

“…Recently, quasi-Yagi antennas have attracted great attention due to their properties, such as high gain, end-fire radiation, planar form, and wide bandwidth. [13][14][15][16][17] Thus, they can be a good candidate for multiband antenna design. Designing a multiband quasi-Yagi antenna, however, is very challenging as the general characteristics of the antenna can easily be distorted for different frequency bands.…”

“…Similarly, monopole antennas exhibit low gain, and it is difficult to maintain the radiation characteristics of the antenna at different frequency bands. Recently, quasi‐Yagi antennas have attracted great attention due to their properties, such as high gain, end‐fire radiation, planar form, and wide bandwidth 13–17 . Thus, they can be a good candidate for multiband antenna design.…”
