“…In the designs of the notebook computers, the antenna plays an important role regarding to stable wireless connection. For wireless local area network (WLAN) notebook antenna designs, the antennas are popularly placed along the top edge of the supporting metal frame of the display [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] owing to providing better wireless coverage and being away from the system-level noise. Many promising antennas for notebook computer applications, including the short-circuited monopole and planar inverted-F antennas (PIFAs) [1][2][3][4][5][6][7][8][9], coupled-fed monopole and PIFAs [10][11][12], slot antennas [13][14][15], etc.…”

Abstract-A small-sized loop antenna loaded with the series-connected capacitor and inductor for wireless local area network (WLAN) operation is proposed. The main radiator of an L-shaped, loop structure and its small ground were constructed on a single-layered FR4 substrate of thickness 0.8 mm and occupied a miniature size of 5 mm × 20 mm only. It was found that by loading the series-connected capacitor and inductor between the antenna feed port and the loop radiator, the quarter-wavelength loop resonance can be easily excited together with the controllable half-wavelength resonance. The design prototype was able to operate in the 2.4-GHz (2400-2484 MHz) and 5.8-GHz (5725-5825 MHz) WLAN bands. The proposed antenna was simple in structure and yet provided dual-band operation and good radiation performance.

“…Over the past 10 years, a large number of MIMO/diversity antenna systems has been investigated for mobile/wireless handsets [4]- [7]. Most of the MIMO/diversity antennas were developed for WLAN/WiMAX/LTE handsets in a single band, such as the 2.4-GHz band [4], the 5-GHz band [5], the 3.5-GHz band [6], or the 2.6-GHz band [7]. Dual-band MIMO antennas were also developed for the 2.4/5-GHz WLAN bands [8], the GSM 900-MHz/WLAN 2.4-GHz bands [9], or the UMTS (1920-2170 MHz)/WLAN 2.4-GHz bands [10].…”

-In this paper, a compact monopole microstrip antenna is presented for dual-band WLAN mobile modules operating in 2.4 GHz and 5.2GHz bands. A novel dual-broadband multiple-input-multiple-output (MIMO) antenna Set Top Box (STB) system is developed. The bandwidths (return loss 10 dB) achieved for the dual-band antenna element are 2.4 GHz (20%) for the lower band and 5.2 GHz (38%) for the upper band. Various configurations of this monopole antenna for MIMO application are also studied. It is shown that good MIMO performance can be achieved even for small element spacing. Simulation results are compared and discussed. Promising small-size WLAN monopole antenna suitable to be mounted along the front edge of the STB with metal housing is presented. The antenna is formed by a two branch structure of a monopole strip and a loop strip. The antenna has attractive features of low profile and wideband operation.

“…In order to realize the unidirectional radiation pattern, the antenna size becomes larger [4] [6] [8]. A higher order mode maybe excited in such antenna and large ripples may exist in the radiation pattern at the upper frequency bands [4]- [6]. The interference and the antenna gain reduction may occur due to the large ripple for base station or access point applications.…”

A low profile dual-band multiple-input-multiple-output (MIMO) antenna system is proposed. The proposed MIMO antenna consists of two low profile unbalanced fed inverted L antennas with parasitic elements to resonate at 2.45 GHz and 5 GHz. The structure is uncomplicated by locating two ultra low profile inverted L antennas on the finite conducting plane. The proposed MIMO antenna is numerically and experimentally analyzed. When the size of conducting plane is 55 mm by 55 mm and the height of antenna is 9 mm, the directive gain of 4.11 dBi and the S11 bandwidth of 5.71% are achieved for lower frequency of 2.45 GHz. At the upper frequency of 5 GHz, the directive gain of 8.22 dBi and the S 11 bandwidth of 6% are obtained. The proposed antenna has good diversity gain, shown by the correlation coefficient becomes less than 0.005 at the frequency of 2.45 GHz and 5 GHz band when the distance between inverted L elements is 41 mm. A good agreement between calculated and measured results is obtained. The results show that the weak mutual coupling of the proposed antenna and this feature enables it to cover the required bandwidths for WLAN operation at the 2.4 GHz band and 5 GHz band.
