A dual-frequency compact microstrip patch antenna
In this paper, a new dual-frequency, compact antenna, which uses an H-shaped microstrip patch with a shorting pin, is described. Compared with the conventional rectangular patch antenna, this antenna can achieve both a significant reduction of antenna size and a dual-frequency operation with a single feed. More freedoms for tuning the resonant frequencies, the frequency ratio, and the input imp...
متن کاملDual Frequency Hexagonal Microstrip Patch Antenna
The study of Microstrip patch antennas have made great progress in recent years. Compared with conventional antennas, Microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the Microstrip patch antennas can provide dual and circular polarizations, d...
متن کاملFdtd Analysis of a Dual-frequency Microstrip Patch Antenna
Characteristics of a single-layer, dual-frequency microstrip patch antenna, which uses a T-strip loaded rectangular microstrip patch, are studied. This antenna is easy to achieve good impedance matching at both frequencies by tuning the feed position and other design parameters. Another advantageous aspect is that it has high polarization purity. A detailed parameter study is performed and the ...
متن کاملCompact Shorted Microstrip Patch Antenna for Dual Band Operation
In the present paper notch loaded shorted microstrip patch antenna has been analysed using cavity model. The proposed antenna shows dual band operation which depends on notch dimensions as well as shorting wall. The frequency ratio is found to be 1.5278 for the notch loaded rectangular patch, while in notch loaded shorted patch, the frequency ratio varies from 2.9764 to 2.725 for increasing val...
متن کاملSingle Patch E - Shaped Compact Microstrip Antenna
Micro strip antennas have been the subject of some inventive work in recent years, and are currently one of the most dynamic fields in antenna theory. A single wideband, E-shaped, compact microstrip antenna is presented in this article in order to be employed for high speed WLANs operating in the C band range. Employing only a single patch, a high impedance bandwidth is achieved. The simulated ...
