In this paper a design of hybrid triangular gap-coupled rectangular microstrip antenna for multiband operation is presented. The proposed antenna is printed on the glass epoxy substrate material of dielectric constant εr = 4.2 with thickness 1.6 mm. This antenna consists of a hybrid triangular radiating patch which is placed above the conventional rectangular microstrip antenna (CRMSA) with gap of 2 mm. The antenna is excited through a simple microstripline feed. Proposed antenna is operates between the frequencies from 2.80 GHz to 11.85 which gives a six operating bands with reasonable impedance bandwidth. A maximum gain of 3.4 dB is observed in its operating bands and gives a broadside linearly polarized radiation characteristics. The measured and simulated results of the antennas are in good agreement with each other. The design concepts of the proposed antennas are given and results are presented and discussed. This antenna may find application in wireless communication such as WLAN, IEEE 802.11a, C- and X-band and satellite communication.
