Abstract
Microstrip patch antenna (MPA) is suitable for different applications in wireless communications. MPA suffers from low gain and narrow bandwidth. In this paper we improved its bandwidth by inserting multiple slots in its ground plane. We used FR-4 substrate to design this antenna. The dimensions of this antenna are 60mm and 80mm. The dielectric constant is equal to 4.4 and the height is 1.6mm. We inserted up to 12 slots in ground plane with 1mm width. The spacing between slots is 3mm slots were arranged parallel to the feeding line. Simulation was done using HFSS simulator.
Highlights
Communication systems deals with transmitting information bearing signals through channel from transmitter to the receiver
Microstrip patch antenna (MPA) are commonly used in different Communication systems because of their small size, high gain and their wide coverage pattern
In (Abu Tarboush, Al-Raweshidy, & Nilavalon, 2009), authors improved antenna bandwidth by 25% which was obtained by inserting slots on ground plane and stacked patch supported by wall
Summary
Communication systems deals with transmitting information bearing signals through channel from transmitter to the receiver. Bandwidth improvement by 4.81% for 100MHZ, 28.89% for 610MHz, 9.13% for 630MHz and 9.13% for 110MHz. In (Abu Tarboush, Al-Raweshidy, & Nilavalon, 2009), authors improved antenna bandwidth by 25% which was obtained by inserting slots on ground plane and stacked patch supported by wall. In (Abu Tarboush, Al-Raweshidy, & Nilavalon, 2009), authors improved antenna bandwidth by 25% which was obtained by inserting slots on ground plane and stacked patch supported by wall This design doesn’t affect the frequency of operation. In (Liu, Cheung, & Yuk, 2011), Slots of different shapes triangular or rectangular were placed on the ground plane under the feed line of the radiator for bandwidth improvement and impedance matching
