The paper presents an O-shape multiband monopole antenna design (Antenna-1) with different patch orientations; 90-degree (Antenna-II) and 180-degree (Antenna-III). The proposed Antenna-I is a multiband integrated wideband monopole antenna with two integrated bands supporting modern wireless services such as Bluetooth and Wireless Local Area Network (WLAN) in addition to wideband covering upper Ultra-wideband (UWB) frequencies. The first band ranges from 2.05 to 3.05 GHz and second band from 3.65 to 3.92 GHz in the - 10 dB impedance bandwidth range. The wideband covers upper frequencies (5.24-10.75 GHz) in the range of Ultrawideband. Antenna-II resonates at 2.38 GHz (2.11-2.90 GHz) covering Bluetooth band and upper UWB region 5.18-10.86 GHz. The proposed Antenna-III covers 1.96-2.33 GHz and 3.74-10.46 GHz frequency bands. The antenna gain at integrated band is around 2.8 dBi and varies from 4 dBi to 8.03 dBi in the UWB region. The measured fidelity factor is 0.89 for face to face and 0.82 for side by side. Measured results are presented to validate the antenna performances.
