Monolithic conformai microstrip patch antenna
2016 International Conference On Communication Problem-Solving (ICCP), 2016The accurate analysis of the antenna performance is very difficult with the complex structure of the conformai antenna, and the conformai finite difference time domain(FDTD) method is one of the effective methods. A millimeter wave monolithic microstrip antenna, formed on the surface of conical surface using the conformal FDTD algorithm, is introduced,

Frequency reconfigurable microstrip patch antenna
2012 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2012A frequency reconfigurable microstrip patch antenna is proposed. Three switches are used to produce six reconfigurable frequencies. Those switches are positioned in the slot places underneath the patch. A reflector is placed behind the antenna. It was found that, at all frequencies, directional radiation patterns are obtained.

Polarization reconfigurable microstrip patch antenna
Microwave and Optical Technology Letters, 2013AbstractThe performances of a quasilumped coupler with a pair of capacitors are first described. By varying the capacitance value of the capacitors, the coupler can operate at three different modes, including uncoupled‐line mode, quadrature hybrid mode, and T‐junction power divider mode. Based on the coupler design, a microstrip antenna with switchable

Square Spiral Microstrip Patch Antenna
2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE), 2019Our project describes the analysis and design of square spiral microstrip patch antenna for multi band frequencies. As compared with old conventional antennae, microstrip patch antennae have more advantages and better prospects. Such antennae are light-weighted, circularly polarized and can be easily fabricated.

Compact GPS Microstrip Patch Antenna
MILCOM 2007 - IEEE Military Communications Conference, 2007In this paper, the effect of shorting wall length on the circular polarization of shorted microstrip patch antenna is examined. The theoretical analysis is based on the High Frequency Software Simulator (HFSS®). A designed antenna for the GPS application at the civilian GPS frequency (1.575 GHz) has been fabricated and measured.

Center-fed microstrip patch antenna
IEEE Transactions on Antennas and Propagation, 2003A novel feeding scheme for microstrip patch antennas is presented, which consists of a coaxial probe and shorting pin separated by a narrow slot centrally cut at the radiating patch. The impedance and radiation characteristics of a conventional probe-fed microstrip patch antenna and the proposed microstrip patch antenna are experimentally examined and ...
