The structure consists of the intersection of two circles of the same radius with their centres displaced by a small fraction of the wavelength . This antenna provides wide impedance bandwidth and excellent isolation between its ports. The gain of the antenna is comparable to that of a standard circular microstrip antenna operating at the same resonant frequency. A theoretical analysis for calculating the resonant frequencies of the two ports is also presented 1996-08-15T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/1577 Analysis of Cavity Backed Printed Dipoles K G Nair; Aanandan,C K; Mohanan,P; Supriyo,Dey The closed form expression for the radiated power of a half-wave microstrip patch is modified to calculate the impedance bandwidth of a printed dipole. Analyses of cavity backed flared and end-loaded printed dipoles are presented 1994-02-03T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/1574 Backscattering Reduction of Corner Reflectors using SCS Technique K G Nair; Aanandan,C K; Mohanan,P Reduction of radar cross -section of dihedral corner reflectors using simulated corrugated surface (SCS) is reported. The technique is found to be more effective in the reduction of RCS or corner reflectors for normal incidence . A typical reduction of 40-50 dB is achieved using this method. 1992-10-01T00:00:00Z http://dyuthi.cusat.ac.in:80/xmlui/handle/purl/1569 Analysis of a New Compact Microstrip K G Nair; Aanandan,C K; Mohanan,P; Jacob,George Abstract-A new compact microstrip antenna element is analyzed. The analysis can accurately predict the resonant frequency, input impedance, and radiation patterns. The predicted results are compared with experimental results and excellent agreement is observed . These antenna elements are more suitable in applications where limited antenna real estate is available. 1998-01-01T00:00:00Z
