Planar Compact Multi-Band C-Shape Monopole Antenna With Inverted L-Shape Parasitic Strip for Wimax Applications

Abstract

Abstract-A novel compact multi-band design of planar C-shape monopole antenna with inverted L-shape parasitic strip is proposed for IEEE 802.16 m WiMAX system.The obtained impedance bandwidth across the 2.6/3.5/5.5 GHz operating bands can reach about 240/570/4470 MHz, respectively. Only with the antenna size of 15 × 30 × 0.8 mm 3 , the proposed monopole antenna has the compact operation with more than 25% antenna size reduction. The measured peak gains and radiation efficiencies are about 1.6/1.9/2.9 dBi and 91/96/94% for the 2.6/3.5/5.5 GHz operating band, respectively, with nearly omni-directional pattern in the XY -plane.

Dual-Band Mimo Antenna With High Isolation Application by Using Neutralizing Line

“…The design concept is based on a simple C-shaped dual-band monopole antenna which has two current paths to generate two operating bands. As proposed in [7][8][9][10], the compact multi-band monopole antennas are usually the meander type structures such as S-shaped, F-shaped and C-shaped ones. These antenna configurations can provide multiple current paths to generate multiband operation.…”

“…3. The maximum measured peak antenna gain and total radiation efficiency is 3.0 / 4.3 / 5.2 dBi and 88 / 95 / 97 % at 2.6 / 3.5 / 5.5 GHz, respectively, which is more than that of those presented monopole antenna designs [1][2][3][4][5][6][7][8][9]. Furthermore, the simulated and measured 2D radiation patterns in the X-Y plane centered at 2.6 / 3.5 / 5.5 GHz are plotted in Fig.…”

“…Several promising monopole antennas with multi-band operation for WiMAX applications have also been demonstrated [1][2][3][4][5]. Planar slot antennas turn out to be the most popular candidates contributing in low profile, wider impedance bandwidth, suitable to be printed on the system circuit board of portable devices, and easily fabricated at low cost for practical applications.…”

A PLANAR COMPACT TRIPLE-BAND MONOPOLE ANTENNA FOR WLAN/WiMAX APPLICATIONS

“…The triple-band antenna using two U-shape slots [8], antenna with taper slot etched in ground [9], and a square slot antenna with crooked T and F-shape strips [10] are presented to realize multiband. The application of parasitic elements are also studied to obtain multiband antenna, such as a meandered strip connecting a rectangular patch on the bottom of the antenna by a plated-through via [11], a triple-band rectangular monopole with a circular resonance patch [12], a triple-band C-shape monopole antenna with inverted Lshape parasitic strip [13], and a multiband planar monopole antenna that contains some different types of branches and one parasitic element [14]. Moreover, metamaterial and fractal structure are used in the design of multi-band antennas, such as a monopole antenna uses a single-cell metamaterial loading to achieve triple-band [15], a modified fractal rhombic patch monopole antenna to realize multiband [16], and a multifrequency antenna realized by split ring resonators [17].…”
