Abstract
AbstractA multiband quasi‐Yagi antenna using a stepped driver and slotted ground for the applications of 2.4/3.5/5.2 GHz bands is presented. The ground plane modifications match impedance and help form the resonances, while the stepped driver parameters allow independent control of resonance frequencies. The antenna shows multiband characteristics and has achieved dB in three different frequency bands of 2.15–2.65, 3.4–4, and 5–5.3 GHz. Furthermore, the antenna shows a stable gain of around 3.9–4.9 dBi and retains its general radiation characteristics for all frequency bands. The simulation and measurement results agree well with each other. The proposed antenna is suitable for applications requiring general quasi‐Yagi antenna characteristics for wireless communications applications for WLAN, WiMAX, ISM, and Bluetooth frequency bands.
