C-band microstrip patch linear array antenna for microwave radio relay
Tóm tắt
An innovative and compact microstrip patch array antenna with rectangular slots for microwave radio relay application is proposed. The designed antenna is applicable in c-band. The antenna is designed on FR4 epoxy substrate with inset feed. The proposed single patch microstip antenna has a return loss (S11), gain and VSWR of −18.30, 3.07 dB and 2.24 at 6.18 GHz and −13.49, 3.07 dB and 3.97 at 10.87 GHz respectively. High Frequency Structural simulator (HFSS 13) is used to simulate and analyse the rectangular patch array antenna. Later, a linear array of 1 × 4 has been designed and its parametric analysis is obtained. The proposed array antenna has the return loss (S11) of value −33.47 dB at 6.4 GHz. The gain of the proposed array has been obtained as 2.707 dB and VSWR of value 1.69 at 6.4 GHz which is also applicable for c-band microwave radio relay.
