Abstract :
A miniature wideband switchable notch antenna was designed for wireless multistandard terminals. The antenna, a quarter-wavelength notch antenna, integrates at its open end a PIN-diode switched capacitor to create two selectable bands at 880-960 MHz (GSM-900) and 1710-3200 MHz (DCS-1800, IMT-2000, LTE, WiFi-802.11b/g/n). It features a small size of λ/14 at the lowest frequency (880 MHz) and covers both bands with a VSWR <; 3:1 and an efficiency between 50% and 85%.
