Stacked Microstrip Antenna with High Gain for Wireless Camera System

A 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...

Frequency Agile Stacked Circular Microstrip Antenna for Wireless Systems

A new frequency agile BST varactor loaded stacked circular microstrip antenna is presented. The antenna is analysed using extended cavity model. One of two bands of antenna is tunable with the help of BST varactor. The upper band is useful for WiMAX and lower band for other wireless communication systems. Various antenna parameters like return loss, resonant frequency, frequency agility etc. ha...

High Gain of C Shape Slotted Microstrip Patch Antenna for Wireless System

In this paper, a novel C shape slotted microstrip patch antenna with enhanced gain is presented and discussed. The proposed design offers low profile, high gain and compact antenna element. The maximum gain is 7.31541 dBi at 2.31610 GHz, antenna and radiation efficiency are more than 95.5319% and bandwidth is 50% from 1GHz to 3GHz .The proposed design is suitable particular for wireless communi...

A High Gain Dual Stacked Aperture Coupled Microstrip Antenna for Wideband Applications

This paper presents the design of a dual stacked microstrip antenna over the frequency range of 9.5–16 GHz. Investigations show that in the new structure the impedance bandwidth of the antenna is increased to 44% and the thickness of the antenna decreases to 0.14λ. Furthermore, the gain bandwidth of the antenna (above 8 dB) is increased to 5.1 GHz (40%).
