Received Jul 7, 2019 Revised Oct 10, 2019 Accepted Oct 22, 2019 Keywords: Chebyshev low pass filter prototype Computer simulation technology (CST) Glass epoxy FR-4 substrate Impedance bandwidth Microstrip filtering antenna Modified shaped slots ABSTRACT This paper presents a new compact microstrip filtering antenna with modified shaped slots to improve the impedance bandwidth. The design structure is printed on one side of a glass epoxy FR-4 substrate with dielectric constant er = 4.4 and thickness h = 1.6 mm. The microstrip filtering antenna consists of three parts; the monopole radiating patch antenna, the SIR filter, and the feeding microstrip line. [...]set them all together and implement some fine-tuning. Broadband is one of the most important requirements for modern digital communication which required transmitting and receiving a huge bit rate. [...]this design is suitable for high speed data communication.
