Abstract
In this work, a multi frequency microstrip antenna (MSA) for wireless applications is
designed. The proposed MSA comprised of elliptical patch antenna with shorting pin. This
antenna is fed by coaxial probe. The design parameters are major and minor axis of elliptical
patch, the position of shorting pin and feeding point of probe are mentioned in table-1. The
proposed antenna can provide optimized multi frequency by varying the above design
parameters. FR-4 substrate with dielectric constant 4.4 is chosen. The multi frequencies are 4.49
GHz, and 6.69GHz, which covers the applications such as satellite communications, for full-time
satellite TV networks.
And for the second case, the work is as a novel design of a Pentagonal shaped patch
antenna is presented for ultra wideband wireless communication applications. Designed
Microstrip patch antenna consists of a pentagonal patch which is found to resonant at frequency
4.8571 GHz, with return loss -19.65 dB having satisfactory radiation properties. The proposed
antenna is a compact design of 30mm × 20mm area on the FR4-epoxy substrate with dielectric
constant of 4.4 and thickness of 1.8 mm. The designed antenna structure with 3.45 dB gain is
planar, simple and compact hence it can be easily embedded for wireless communication systems
and integrated with microwave circuitry for low manufacturing cost.
