Dual‐band slot antenna for 2.4/5.2 GHz WLAN operation

Abstract

A dual‐band slot antenna comprising two narrow linear slots for wireless local area network (WLAN) operations in the 2.4 GHz (2.4–2.484 GHz) and 5.2 GHz (5.15–5.35 GHz) bands is presented. The two linear slots are arranged to be close and in parallel to each other, and are easily fed by using a single 50 Ω coaxial cable to achieve two desired operating modes at about 2.4 GHz and 5.2 GHz. A prototype of the proposed antenna with a narrow width of 10 mm suitable to be placed along the perimeter of the display of a notebook computer is constructed and studied. Experimental results of the constructed prototype are presented. © 2002 Wiley Periodicals, Inc.

Capacitor-Inductor-Loaded, Small-Sized Loop Antenna for Wlan Notebook Computers

“…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.…”

“…The antenna type used in this study is of loop antennas, which are substantially different from those notebook antennas studied in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Loop and folded loop antennas have been favorable to applications in WLAN access points [16][17][18][19][20][21][22] and mobile phones [23][24][25][26][27] owing to their self-balanced structure of one-wavelength loops [16][17][18][19][20][21][22] and offering multi-resonant modes [23][24][25][26].…”

Dual Band Two Elements Inverted-L Antenna for 3.5 & 5 Ghz Mobile Wimax/Wi-Fi Applications

“…If the monopole antenna is designed in ring shaped or hook shaped the gain is not over 2.8 and 4.29 dBi at frequency 2.4 and 5 GHz respectively [3], [4]. Moreover, dual band slot by using two linear slot are arranged to be close, equilateral triangular slot antenna, compact double L-slit or compact dual band slot antenna has the moderate gain in both frequencies but the antenna geometry are not simple [5]- [8]. Though the dual band rectangular slot antenna has simple geometry but the gain is limited to 4 and 5 dBi at frequency 2.4 and 5 GHz band respectively [9].…”

Compact Dual-Band Slot Antenna for 2.4/5GHZ Wlan Applications

“…Numerous slot antennas for 2.4/5 GHz operations have been reported in the past few years [5][6][7][8]. In [5] and [6], the proposed slot antennas only cover a part of the 2.4/5 GHz bands.…”

“…In [5] and [6], the proposed slot antennas only cover a part of the 2.4/5 GHz bands. The proposed antennas in [7] and [8] can wholly cover the 2.4/5 GHz bands, but are not very compact and will cause inconvenience when integrated with other circuits.…”
