“…To meet the WLAN standards in the 2.4 GHz (2.4-2.484 GHz)/5.2 GHz (5.15-5.35 GHz)/5.8 GHz (5.725-5.825 GHz) operating bands and the WiMAX standards in the 2.5 GHz (2.4-2.6 GHz)/3.5 GHz (3.4-3.6 GHz)/5.5 GHz (5.25-5.85 GHz) bands, multiband antennas with compact size, low cost, and easy fabrication are required. Various types of multiband antenna designs have been reported [1][2][3][4][5][6][7][8][9][10][11]. Some of them only can fulfill the requirement of the WLAN or WiMAX band, such as the monopole antennas [1][2][3] and the slot antennas [4][5][6].…”

Abstract-A novel meander antenna with tri-band operation is presented for WLAN and WiMAX applications. The proposed antenna consists of a rectangular meander with two asymmetrical L-shaped strips. The rectangular meander is used for the lower band operation at 2.5 GHz. The left L-shaped strip is employed to generate the higher resonant mode at about 5.5 GHz, while the right L-shaped strip is employed to create a new resonant mode at 3.5 GHz and enhance the bandwidth of the middle band operation. Prototype of the proposed antenna has been constructed and experimentally studied. The measured 10 dB return loss bandwidths at the resonant frequency of 2.5, 3.5, and 5.5 GHz can be up to 520 MHz (2.18-2.70 GHz), 800 MHz (3.34-4.14 GHz) and 830 MHz (5.07-5.90 GHz), respectively. The antenna is simple in configuration and has a compact dimension of 37 × 42 × 1 mm 3 .

“…2(b), it can be analyzed in even-oddmode theory. T-shaped stubs have been loaded in some other circuits to improve the performances [15][16][17][18][19][20][21]. The presented T-shaped can be used in microstrip circuits to crate dual controllable transmission zeros for sharper skirt and some other better performances.…”

Abstract-A wideband differential bandpass filter (BPF) with differential mode passband and common mode suppression is proposed and implemented on microstrip lines for wideband application in this letter. The initial BPF is similar to a single ring resonator with two unequal feed lines which have 180 • separation and T-shaped stubs are loaded on the ring resonator to form an improved one for better performances. The lengths and widths of these stubs can be adjusted to produce a highly selectivity under the differential mode and improved attenuation under the common mode. This simple, compact structure is easy for construct without any coupling structure. Finally, a microstrip differential wideband BPF is designed, simulated, fabricated, and measured. The presented differential BPF has a 3-dB fractional bandwidth (FBW) of 38% for the differential mode and insertion loss greater than 17 dB for common mode. Good agreement between simulated and measured results is obtained.

“…There are various impedance matching and feeding techniques used to achieve wide bandwidth [3][4][5]. Using some narrow slots or removing some portion from the resonators such as patch loaded with U-slot [6,7], W-slot [8], V-slot [9], T-slot [10] and fractal shaped patch [11,12] provides a compact antenna with enhanced bandwidth. An asymmetric E-shaped patch and proximity coupled patch antenna [13,14] also provide improved bandwidth, but the overall size is compromised.…”

Abstract-In this article, a novel design of butterfly-shaped compact and small size microstrip antenna is proposed. The radiating structure consists of four circular discs in coalesced form and fed with coaxial probe. The initial antenna resonates at 9.64 GHz with impedance bandwidth of 11.41%. The resonance frequency is further reduced to 8.12 GHz with bandwidth 10.10%, when a rectangular slot is incorporated in the initial patch. Finally, two parallel slots are embedded in the initial patch which improves the antenna bandwidth up to 21.50% (6.02-7.47 GHz). The gain and efficiency of this antenna are above 8.80 dBi and 90% respectively across the entire operating band. Radiation pattern is calculated at lower end (6.02 GHz), upper end (7.47 GHz) and centre frequency (6.75 GHz) of operating band. The proposed antenna is fabricated, and measured results are validated with the simulated ones.
