The idea of micro-strip patch antenna was proposed by De-Chaps in 1953.First radiator was developed by Bob Munson in 1971. In the last decades printed antennas have been largely studied due to their advantages over other radiating systems, which include: The unique property of the micro-strip patch antenna is its two- U-slot patch antenna [12] can excite higher order TM 02 mode, which can broaden the bandwidth of the dual-beam antenna, however, the gain difference between two beams could be around 2 dB, which I would like to simulate a patch antenna with U-slots and/or slots in general. Can I add slots in the metal patch, ie remove the metal from the metal patch so I can create a U-slot patch antenna. General can I make a arbitrary metal patch with slots, above the infinite groundplane. Multi Band Curved U-Slot Edge Feed Triangular Micro-strip Patch Antenna. IRJET Journal. PDF. Download Free PDF.

Among the topics are a review of some background materials, characteristics of the circular patch antenna, the U-slot patch antenna, techniques for reducing size, and circular polarization.

A wideband circularly polarized reconfigurable patch antenna with L-shaped feeding probes is presented, which can generate unidirectional radiation performance that is switchable between left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP). To realize this property, an L-probe fed square patch antenna is chosen as the radiator. A compact reconfigurable feeding CONCLUSION A Co-axial probe fed W-shaped microstrip patch antenna with Inverted U-shaped slots in ground is designed for wide band wireless applications. The antenna is very compact with minute dimensions of 32mm x 32mm x 1.6mm prototyped on FR-4 substrate. The U- slot patch antenna is designed for increasing the bandwidth and return loss but gain cannot increase. If array of the U- slot patch antenna is used then the gain can be im- proved. Therefore, the antenna will be better work in the Wi- MAX applications and wireless communications system. In the second example, a 5 5 array of interacting U-slot and U-strip antennas (Fig. 5) in an overmoded rectangular wave- guide transition is investigated for operation at X-band. The nu- Fig. 4.

A single layer microstrip patch antenna is designed for wideband applications. The proposed antenna is simulated using Finite Element method based High Frequency Structure Simulator version 13. The simulated results are par to the theoretical results. II. ANTENNA DESIGN The proposed antenna has dimensions of 32mm x 32mm x 1.6mm. In this paper, we propose a dual-band microstrip patch antenna with u-shaped slot fed by coaxial feeding technique. The proposed antenna is designed, simulated and optimized using Ansoft HFSS Vs 13. The simulation results are presented in terms of return loss, VSWR, input impedance, Gain and radiation pattern. The microstrip patch antenna calculator determines the length (L) and width (W) of a rectangular microstrip patch antenna for a given resonant frequency or vice versa. The substrate parameters (ε r and h) are required. If the ratio (L/W) is close to unity, the radiation pattern will be symmetric but may not provide a resonable input impedance.

In some applications it is required to have dual band characteristics instead of single band. This characteristic can be obtained by embedding a U-slot in the patch and hence the radiating patch includes a pair of step-slots. In this paper, we propose a dual-band microstrip patch antenna with u-shaped slot fed by coaxial feeding technique. The proposed antenna is designed, simulated and
