RamaDevi K., Rani A.J., Prasad A.M. (2017) Design of Microstrip Antenna with Improved Bandwidth for Biomedical Application. In: Satapathy S., Bhateja V., Joshi A. (eds) Proceedings of the International Conference on Data Engineering and Communication Technology. Advances in Intelligent Systems and Computing, vol 468. Springer, Singapore How to change the antenna structure to improve bandwidth ... feed the antenna using aperture slot coupling. aperture slot coupling has the advantage of providing increased bandwidth compared to any other feeding mechanisms. OR if you have 2 substrates in your antenna design, insert a foam material between the two substrates which act as a spacer with dielectric constant almost equal to 1.( it would be a ... Rectangular Planar Antenna Using U-Slot for Bandwidth ... 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 ...

EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots ... Slot antennas are often used at UHF and microwave frequencies instead of line antennas when greater control of the radiation pattern is required.

Novel Design of Microstrip Antenna with Improved Bandwidth

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 How to change the antenna structure to improve bandwidth ... feed the antenna using aperture slot coupling. aperture slot coupling has the advantage of providing increased bandwidth compared to any other feeding mechanisms. OR if you have 2 substrates in your antenna design, insert a foam material between the two substrates which act as a spacer with dielectric constant almost equal to 1.( it would be a ... 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 ...
