A Novel On-Glass Antenna for Mobile Handset Applications

Abstract

In this paper, we propose a novel on-glass multiband 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×25mm 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 focuses on the current trends in the development of compact and low profile mobile handset. For reducing the dimension of the antenna area in the device, the proposed antenna is placed on the inner surface of the glass of the display. Moreover, the antenna design can be against to avoid the degradation in the user handheld condition. The simulated and measured data including return loss, antenna gain and radiation patterns are presented. As a result of the measurement, the antenna design is proper to the GPS and WIFI dual band application in the mobile handset.

A Compact GPS/Wlan Antenna Design for Mobile Terminal With Full Metal Housing

“…Several WLAN antennas were reported to work at WLAN a/b/g band but not at GPS band [4][5][6][7][8]. Other GPS/WLAN antennas were reported to cover 1.575 and 2.4 GHz but not include 5 GHz band [9][10][11][12][13]. There are several papers introduced tri-band antenna design but having fairly large size compared with the proposed antenna as shown in Table 1 [14][15][16][17][18][19].…”

Dual‐band antenna using a C‐shaped dual‐feed for GPS/WLAN applications

“…An increasing demand for high quality electronic devices, high frequency circuits and low cost, has propelled researches for better ceramic materials properties through their characterization, providing a certain priority for new materials that can offer good performance, specially application for microwave systems. In order to meet the specifications of the current and future systems, improved or new microwave components based on dedicated dielectric materials and new designs are required such as the quality factor (Q), the temperature coefficient of resonant frequency (s f ) and dielectric constant (e) [2][3][4][5][6][7]. In the last few years, the addition of low melting point Bi 2 O 3 compound was carried out for the development of new compositions to enhance electrical and dielectric properties in the case of NN (Na 2 Nb 4 O 11 ) [1,8], ceramics and also to reduce the sintering temperature.…”

A very small chip antenna supporting multiple radio protocols

“…Bluetooth applications in the 2.4 GHz band have become a must in almost all of the mobile devices. At the same time, the function of GPS concurrently supported has gradually become a requirement to support location guidance and emergency assistance [4]- [5]. While the above bands already exist in mobile phones, WiMax technology of IEEE 802.16 has come into play for long distance wireless access for both mobile phones and tablets [6]- [7].…”
