Dual U-Slot Microstrip Patch Antenna with Enhanced …
How to change the antenna structure to improve bandwidth…
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.

Feb 13, 2014 · 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. Enhancing the Bandwidth of a Microstrip Patch Antenna dielectric constant of 9.4 and loss tangent of 4.0e-4. The proposed antennas may find applications in Wireless Local Area Network (WLAN). Keywords: - bandwidth, dielectric constant, microstrip antenna, slot patch, substrate I. INTRODUCTION Communication can be broadly defined as the transfer of information from one point to another [1]. How can I increase the bandwidth of a microstrip patch I have designed a microstrip patch antenna in HFSS at 28 GHz, its bandwidth is almost 1.5 GHz. Introduction of slots increase the BW about 30%. ... How can I improve the bandwidth of ... Broadband Circularly Polarized Cross Shaped Slot Antenna Broadband Circularly Polarized Cross Shaped Slot Antenna with an Improved Feedline Kwame O. Gyasi, Guangjun Wen, Yongjun Huang, E.
