Summary: A compact quasi-Yagi antenna with a modified ground plane is designed for a through-wall radar on-chip. The proposed antenna achieves significant miniaturization and a 44.62% increase in impedance bandwidth through a slot-based ground plane modification. At 2.4 GHz, the antenna exhibits high directivity (9.02 dBi) and a front-to-back ratio (25.76 dB). Real-world deployment experiments demonstrate that the performance of the quasi-Yagi antenna is comparable to that of a Vivaldi antenna and a commercial-off-the-shelf horn antenna. The designed antenna successfully obtains spectrogram-based signatures of a moving person behind a wooden partition and a 40 cm thick masonry wall, proving the suitability of the quasi-Yagi antenna for portable applications using a radar-on-chip.
