Mobile Phone Applications

A wideband slot antenna for mobile phone applications is proposed. The antenna has two slots with open ends etched on the opposite edges of the ground plane. The main slot, of total length of 59 mm, is composed of a rectangle connected to a circle having radius of 5 mm. Another slot, having a rectangular shape with width of 2.8 mm and length of 26 mm, is employed to enhance the antenna bandwidth. The slots are fed by means of a rectangular monopole connected to a circular patch joined to a bent 50 Ω microstrip transmission line forming two right angles. To obtain a wideband impedance matching, the upper edge of the monopole and a part of the feeding line evolve along the top edge of the two slots. To reduce the antenna size, the upper part of the board above the slot (just 3 mm from the slot) is folded vertically to the ground plane. The measured bandwidth of the antenna is 0.698–1.10 GHz and 1.64–2.83 GHz covering LTE700/2300/2500, GSM850/900/1800/1900, and UMTS bands.

Mobile Handset

A printed open-ended slot antenna is designed for mobile phone application. The slot has a hybrid structure of a rectangle and a circle cut out of a 60mm×115mm ground plane, and fed by a microstrip line with a circular patch connected to a bent strip on the upper part of the patch. The proposed antenna provides a wide -6dB bandwidth covering 1.73-11GHz. It can be used in DCS1800, PCS1900, UMTS2000, TD-SCDMA, Bluetooth, LTE2.5GHz, WiMax, and UWB
