Broadband Dual Frequency Microstrip Antenna
K G Nair; Aanandan,C K; Mohanan,P; Deepukumar,M; George,J
A new dual port microstrip antenna geometry for dual frequency
operation is presented. 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

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

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.

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.
