A Reconfigurable Stacked Microstrip Patch Antenna for Satellite and Terrestrial Links

Abstract

Abstract-A reconfigurable stacked microstrip patch antenna is proposed. The antenna operates at an upper frequency f u with a broadside pattern, 7.5-dBi right-hand circularly polarized gain, and 15.8% bandwidth. At a lower frequency f l , the antenna operates as a planar inverted-F antenna (7.3% bandwidth and 3.9-dBi peak gain) with the main beam directed close to the horizon. Switching between the two regimes of operation is achieved using p-i-n diodes. Antenna operation in the upper frequency band is suitable for low-earth-orbit or medium-earth-orbit satellite communications, and in the lower frequency band, the antenna is useful for terrestrial land-mobile or other wireless applications.Index Terms-Reconfigurable antenna, satellite link, stacked patch antenna, terrestrial link.

Stacked U Slot Microstrip Patch Antenna for Bandwidth Enhancement

“…Reconfigurable antennas can be used to enhance the bandwidth. It is suitable for terrestrial and satellite links [2]. With this reconfigurable antenna, multiple functions at multiple frequency bands with a single aperture is possible.…”

Design and Development of Coax-Fed Electromagnetically Coupled Stacked Rectangular Patch Antenna for Broad Band Application

“…In addition, stacked microstrip configurations have achieved higher gains and offer the possibility of dual-frequency operation [3]. Today, the stacked patch antennas are used in radars, mobile, satellites, UHF RFID, MIMO and reconfigurable antennas [3][4][5][6][7][8][9][10][11][12][13][14]. Thus, the accurate computation of resonant frequency, input impedance, quality factors, bandwidth and gain of stacked patch antenna is very important to install properly in wireless equipments.…”

Comparative Analysis of Stack Shaped Microstrip Patch Antenna

“…However, by using two multi layered patches with the walls at the edges between these two patches, one can obtain enhanced impedance band width [1]. A compact stack antenna consisting of square loop resonators, aperture couples and feed line was reported for a dual band operation also the stacked structure was utilized for multiband structure again a stacked structure had been applied to an equilateral triangular microstrip patch antennas to reduce its overall size, the stacked structure is utilized for bandwidth enhancement also [1][2][3][4][5][6]. There has recently been noticeable interest in the two layer probe fed patch antenna consisting of a driven patch in the bottom and a parasitic patch [7][8][9][10][11][12][13][14][15].…”
