Abstract: In this paper a novel microstrip fed circular patch antenna is analyzed in details for applications in Bluetooth, UWB, X-band and Ku band respectively. The basic antenna structure is a circular patch which is modified by adding complementary circular split ring resonators and T strip connected to the top of the patch. The antenna is fed by a 50 ohm microstrip feed line. A slot of dimension 2×3.6 mm2 is inserted in the ground plane which consists of a staircase structure having appropriate dimensions. The ground is later modified with meander shaped slots for Bluetooth, X band and Ku band applications. The characteristics of the proposed antenna is carried out in HFSS 2013.

01 Jan 2006TL;DR: In this article, the authors proposed a planar monopole antenna with dual band-notched characteristics, which is suitable for creating ultra-wideband antenna with narrow frequency notches or for creating multiband antennas.
Abstract: Wideband planar monopole antennas with dual band-notched characteristics are presented. The proposed antenna consists of a wideband planar monopole antenna and the multiple U-, ∩-, and inverted L-shaped slots, producing band-notched characteristics. In order to generate dual band-notched characteristic, we propose nine types of planar monopole antennas, which have two or three ∩ (U or inverted L)-shaped slots in the radiator. This technique is suitable for creating ultra-wideband antenna with narrow frequency notches or for creating multiband antennas.

TL;DR: In this paper, the authors proposed a diamond-shaped slot surrounded by a diamond shaped ring in the center of the patch with a defected ground technique to enhance the bandwidth of a traditional circular patch antenna.
Abstract: This paper focuses on the bandwidth enhancement of a traditional circular patch antenna by introducing a diamond-shaped slot surrounded by a diamond-shaped ring in the center of the patch with a defected ground technique. The enhanced bandwidth of 506 MHz ranging from 9.872 GHz to 10.378 GHz is achieved with the proposed design method. Unlike other methods of bandwidth enhancement of a circular patch antenna, this method eliminates the trade-off between BW enhancement, gain and compactness of the antenna. In this paper, also the performance of the proposed antenna have been contrasted over a conventional circular patch antenna. The center frequency is chosen at 10 GHz in the X-band, which is suitable for satellite communication along with other UWB applications. The design and simulation results of the antenna are acquired using CST microwave studio.

TL;DR: In this article, two compact, printed, ultrawideband (UWB) monopole antennas with tri-band notched characteristics are reported, which are achieved by introducing printed, electrically small, capacitively loaded loop (CLL) resonators.
Abstract: Two compact, printed, ultrawideband (UWB) monopole antennas with tri-band notched characteristics are reported. The notched filters are achieved by introducing printed, electrically small, capacitively-loaded loop (CLL) resonators. The directly driven elements consist of printed top-loaded CLL-based monopoles and 50 Ω microstrip feed lines. By adding three CLL elements close to the feed line, band-notch properties in the WiMAX (3.3-3.6GHz), lower WLAN (5.15-5.35GHz) and higher WLAN (5.725-5.825GHz) bands are achieved. Each antenna system is contained on a 27×34mm2 sheet of Rogers Duroid 5880 substrate. One is designed with three additional CLL elements; the other is achieved with only two. Comparisons between the simulation and measurement results show that these UWB antennas have broadband matched impedance values and stable radiation patterns for all radiating frequencies.

TL;DR: In this paper, a simple, low-cost, and compact printed dual-band fork-shaped monopole antenna for Bluetooth and ultrawideband (UWB) applications is proposed.
Abstract: A simple, low-cost, and compact printed dual-band fork-shaped monopole antenna for Bluetooth and ultrawideband (UWB) applications is proposed. Dual-band operation covering 2.4-2.484 GHz (Bluetooth) and 3.1-10.6 GHz (UWB) frequency bands are obtained by using a fork-shaped radiating patch and a rectangular ground patch. The proposed antenna is fed by a 50-Ω microstrip line and fabricated on a low-cost FR4 substrate having dimensions 42 (Lsub) × 24 (Wsub) × 1.6 (H) mm3. The antenna structure is fabricated and tested. Measured S11 is ≤ -10 dB over 2.3-2.5 and 3.1-12 GHz. The antenna shows acceptable gain flatness with nearly omnidirectional radiation patterns over both Bluetooth and UWB bands.

TL;DR: In this article, a novel technique to add an extra Bluetooth band and dual notch bands simultaneously to a compact ultrawideband (UWB) printed slot antenna is proposed, which is in the shape of an octagon and is fed by a rectangular patch with a beveled bottom edge.
Abstract: A novel technique to add an extra Bluetooth band and dual notch bands simultaneously to a compact ultrawideband (UWB) printed slot antenna is proposed. The UWB slot antenna, covering 3.1-11 GHz, is in the shape of an octagon and is fed by a rectangular patch with a beveled bottom edge. To create an extra band outside the UWB frequency range, centered at the 2.4-GHz Bluetooth band, a quarter-wavelength stub is attached to the high concentrated current area in the ground plane. Two notch bands, centered at 3.5-GHz WiMAX and 5.8-GHz WLAN, are also created by placing two stubs similar to that of the extra band. The proposed antenna has a compact size (23 × 28 mm 2), almost stable radiation pattern, and reflection coefficient of lower than -10 dB across the entire passband. A prototype of the proposed antenna is fabricated, and the measured results are shown to be in good agreement with the simulated results.
