Effects of slot loading on microstrip patch antennas

By Author

A Microstrip patch antenna having slotted sides with small capacitive feed has studied and discussed here. Slots on the proposed patch can be used to increase the bandwidth of antenna. It has observed that VSWR bandwidth nearly 45% can be easily achieved with the novel patch. A constant radiation pattern with improved

A dual-frequency compact microstrip patch antenna use the rectangular microstrip patch loaded with one shorting pin. Other dual-frequency antennas with square slot or rectangular slot loading are reported by Chen [1998] and Gaa and Li [1999a]. To satisfy specific requirements of various practical applica- tions, more research results on the dual-frequency microstrip antennas are still required. ENHANCEMENT OF BANDWIDTH AND GAIN OF A RECTANGULAR MICROSTRIP ... In this project, method of moments based IE3D software is used to design a Microstrip Patch Antenna with enhanced gain. The aim of the project is to design a rectangular Microstrip Patch Antenna with enhanced gain and bandwidth and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative Dielectric constant ... An Introduction of Aperture Coupled Microstrip Slot Antenna

Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas

Bhunia,” Effects of Slot Loading on Microstrip Patch Antennas”, International Journal of Wired and Wireless Communications Vol.1, Issue 1, October, 2012 Broadband Microstrip Patch Antenna using Slot etc. It is well known that the major drawback of a microstrip antenna is its narrow bandwidth [2]. One of the popular techniques for broadening the patch antenna bandwidth is to incorporate U-slot on its surface [1]. In this communication [4] a microstrip patch antenna using dual U-slot with broad bandwidth (>37%) is proposed.

Broadband Microstrip Patch Antenna using Slot

A dual-band microstrip patch antenna was designed using genetic ... Multiport analysis was used to determine the effects of the slots or pins on the input impedance, and thus assign fitness values to each of the antennas [4]. Genetic algorithms can also be used to change the shape of the patch itself and thus optimize the
