Affiliation: AA(Dept of ... Study and Design of Broadband Bow-tie Slot Antenna Fed ... - NSFC length of one ACPW slot, the impedance characteristic of the antenna is greatly improved so that the bandwidth is broadened. Meanwhile, to improve the gain at ... Broadband Slotted Coaxial Broadcast Antenna Technology - Dielectric
or antenna sections as long as the phase offset conforms to equations (11) and (12). It does however include a real slot antenna response and the actual phase run out in the sections connecting feed lines due to the frequency spread. As is seen in Figure 14, the expected gain in bandwidth will improve between
On the contrary, the major disadvantage of these types of antennas is the lower and narrow bandwidth[1-5]. Combination of the coplanar waveguide feed, antenna geometry, and a variety of slot shapes is a solution to improve and enlarge the antenna operating bandwidth[6-8]. Printed Wide-Slot Antenna Design with Bandwidth and Gain ... This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to excite the square slot. The rotated square slot is embedded in the middle of the ground plane, and ... T-slot PIFA with Enhanced Bandwidth for Mobile Handset
A Coplanar Waveguide Fed Two Arm Archimedean Spiral Slot Antenna With Improved Bandwidth Abstract: A compact wideband circularly polarized (CP) printed antenna design is presented in this communication. The proposed antenna consists of two Archimedean spiral slots, loaded with two chip resistors and fed by a coplanar waveguide (CPW ...

Design and Simulation of an Improved Bandwidth V-Slotted
A Bandwidth Improved Circular Polarized Slot Antenna Using A circular polarized (CP) slot antenna is designed with a slot composed of multiple circular sectors (MCS). The design has advantages of having a wide 3 dB axial ratio (AR) bandwidth of 57.4%, achieving a good AR smaller than 2 dB in most areas of the frequency range. The design of the antenna follows a multi-objective optimization procedure that applies computational power rather than human
How can I increase the bandwidth of a microstrip patch ...
A single layer single element rectangular microstrip antenna on ridge ground plane for improved bandwidth is theoreti-cally investigated with a view to develop a concrete physical insight in to the phenomenon. The simple single element An Introduction of Aperture Coupled Microstrip Slot Antenna A microstrip slot antenna is very small and lightweight still it has the problem of back radiation due to which power loss occurs and the SAR increases. To reduce the back lobe a technique introduces i.e. aperture coupled microstrip slot antenna which reduces the back lobe as well as increases the bandwidth of the antenna. Rectangular Planar Antenna Using U -Slot for Bandwidth ... Rectangular Planar Antenna Using U-Slot for Bandwidth Improvement . impedance bandwidth (return loss less than -10 dB) is 500 MHz (2.2-2.7 GHz). Figure 7. Calibration Kit 3.5 mm . After the calibration, the return loss for the achieved antenna as shown in the following figure is tested. In the same time, both the s on ADS simulationand CST with Multiband Wireless Microstrip Antenna with Embedded Meta ... bandwidth 3GHz=34.1%. The bandwidth is improved up to 37% compared with rectangular patch antenna. Fig. 6 shows the S 11 parameter. Fig. 6. S 11 parameter of Meta-material embedded rectangular patch antenna From the radiation pattern given in Fig. 7, meta-material embedded rectangular patch antenna gives an improved gain of 2.53dB.
