Design of a High Isolation Dual Polarized S-band Microstrip Patch Antenna
نویسندگان
چکیده
An isolation enhanced dual polarized microstrip patch antenna has been designed for Sband Synthetic Aperture Radar. This antenna operates at 3.125 GHz with operating bandwidth of 150 MHz or 4.8%. The electromagnetic power is coupled from the feed line to radiating patch through proximity coupling feeding technique for better bandwidth achievement. A centre groundshorted microstrip line is created at the feeding layer to enhance the isolation of the input ports. The simulation result illustrates the effect of the ground shorted microstrip line to the isolation of horizontal and vertical polarizations.

A Dual-polarized Shorted Microstrip Patch Antenna for Wideband Application
A new design of a wideband dually-polarized shorted microstrip patch antenna coupled to hook shaped probes is presented. The antenna is designed to operate around 4 GHz. The mechanisms of the shorted microstrip patch antenna provide wider impedance bandwidth over 37%. The shorted patch is smaller than as with to the unshorted patch. The present design provides about 40 dB isolation level betwee...

In this paper, the authors propose a circularly polarized printed antenna combining a slot array antenna and a patch antenna, with dual-band operation. The proposed antenna has good isolation performance, is compact, and has simple configuration. This antenna is composed of two parts, a patch antenna (for Rx) on the top, and a slot array antenna (for Tx) on the bottom, respectively. The element...

A dual-band circularly polarized stacked microstrip antenna for ISM Bands (2.45GHz & 5.8GHz) applications is designed and implemented. By stacking two different corner-truncated square patches in a dielectric substrate layer, the microstrip antenna for dual-frequency circular polarization (CP) can be achieved with −11.5 dB and −12.8 dB measured return loss for 2.45GHz and 5.8GHz. Semicircular g...

Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
متن کاملModified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...
