چکیده
A simple single-feeding circular polarization (CP) antenna with controlled left/right-hand characteristics is proposed and investigated for GPS L2 band applications. To achieve the CP characteristics, four arc-shaped cutting corners different sizes are removed from a patch to give 90∘ phase difference implement CP. By adjusting radius of corners, can be get (L/RHCP). The modeled, simulated, fabricated measured, results demonstrate that provides an axial ratio beamwidth over 180 MHz, impedance bandwidth 20 MHz L/RHCP. Additionally, devised antennas have good directional radiating patterns, making them suitable

Compact CPW-fed Circular Patch Antenna for UWB Applications
In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also ado...

متن کاملA CPW-Fed Dual-Band Slot Antenna with Circular Polarization
In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional rectangular slot antenna. Moreover, by cutting a T-shaped notch on the ground plane, the axial ratio (AR) bandwidth (ARBW) can be extended. The antenna shows left-hand ...
متن کاملGPS Anti-Jam: A Simple Method of Single Antenna Null-Steering for Aerial Applications
In this paper we introduce a backward compatible single antenna design for GPS jam mitigation on aircraft. Similar to our prior work in spoof detection [1], this anti-jam antenna requires no additional signal processing at the receiver, and it fits into the form-factor of a standard GPS antenna. There are two primary modes of operation. During the default mode, the antenna performs comparable t...
متن کاملSingle Antenna GPS Spoof Detection that is Simple, Static, Instantaneous and Backwards Compatible for Aerial Applications
Despite the antenna’s privileged position as the first line of defense against interferers, jammers and spoofers, most detection and mitigation techniques are realized in the receiver’s backend signal processing blocks. Nonetheless, these solutions often require considerable additional hardware added to the receiver’s frontend and antenna design. For example, multi-antenna arrays replace a sing...
