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 کاملSingle-Layer Dual-Band Dual-Linear-Polarization Reflectarray Antenna with Different Beams for Each Band
A novel single-layer unit cell structure is proposed to design a dual-band dual-linearpolarization reflectarray antenna with different beams for X and Ku bands. The unit cell structure is composed of a circular ring and two cross bow-tie structures combined by a circular patch. Five tunable geometric parameters can be optimized to achieve the required phase distributions of the reflectarray ant...
متن کاملInverted S-Shaped Compact Antenna for X-Band Applications
A novel probe-fed compact inverted S-shaped multifrequency patch antenna is designed. By employing two rectangular slots that change the conventional rectangular patch into an inverted S-shaped patch, the antenna is able to operate in triple frequency in the X-band. The performance criteria of the proposed design have been experimentally verified by fabricating a printed prototype. The measured...
متن کاملCompact Two-Layer Slot Array Antenna for K-Band Applications Based on Substrate Integrated Waveguide
A compact two-layer slot array antenna at 24GHz based on substrate integrated waveguide (SIW) technology is presented. The feed waveguide is placed underneath the slot array and is coupled through slanted slots to branches of the array leading to considerable reduction in size compared to onelayer SIW slot array antennas that are fed from one end. Fullwave electromagnetic simulations show excel...
متن کاملA compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
