A frame antenna based on the inverted-F antenna (IFA) structure for the LTE (long term evolution) metal-casing smartphone is presented. The antenna uses a frame section along the short edge of the metal casing as the IFA's radiating strip. There are no gaps required at the two side edges of the smartphone. The frame section is connected to a feed circuit board (FCB) to achieve wider bandwidth. With...
In this paper, we propose a novel on-glass multi-band antenna with a planar inverter F structure for the GPS and WLAN wireless communication. A prototype of the proposed antenna with a compact size of 6mm¡Ñ25mm is experimented in the mobile handset design. The antenna shows operating bandwidths (referenced Return loss-6dB) for covering the GPS in 1.575GHz and WLAN in 2.45GHz. The present design mainly...
