A U slotted H-shaped Micro strip antenna with capacitive feed for broadband application

The wideband microstrip antenna with capacitive feed with the low level of the VSWR

“…The excitation of the E-form microstrip is carried out by means of a capacitive coupling between it and an additional rectangular microstrip. This excitation is called capacitive (capacitive feed) [7][8]. Figure 2.…”

Bandwidth enhancement using modified L-probe fed slotted patch antenna for WLAN and UMTS applications

“…Many attempts have been made to overcome the low gain and narrow bandwidth of the microstrip antenna [1]. In this process, several measures were taken such as modifying the shape of radiating elements [2] and modifying the ground plane structure [3], use of low dielectric constant material, stacked patch antenna, use of impedance matching networks etc. [4–6] and creating defect in the ground plane [7].…”

H And T-Slotted Rectangular Microstrip Patch Antennas for Wireless Communication

“…Microstrip patch antenna are used for mobile phones, satellites, radio, radars, global positioning system (GPS), television, multiple input multiple output (MIMO), radio frequency identification (RFID),medical imaging and guidance of missiles are few examples of the military and industrial applications [3]. Microstrip antennas are most popular because of its numerous advantages in wireless communication systems that typically require antennas with small size, light weight, low profile, and low cost, and that are easy to fabricate and assemble [6].Now-a-days, antennas with multiband capabilities have been widely required in satellite and mobile communication systems to meet the growing system complexity [5]. A good design of the antenna can relax system requirements and improve overall system performance.…”
