## Abstract A circularly polarized cavityβbacked crossed loop antenna is proposed in this article. The optimized overall dimensions of the antenna are 1.13Ξ»~o~ in diameter and 0.267Ξ»~o~ in height (Ξ»~o~ is the freeβspace wavelength at the center frequency), and the circumference of one loop is 1.1Ξ»~

## Abstract In this article, a new slot antenna with a quasiβspiral slot is proposed.A simple microstrip line feed is used to excite the slot antenna. Measurement results show that 10 dB return loss bandwidth and 3 dB axial ratio bandwidth of the proposed antenna are 87 and 43%, respectively. Β© 201
## Abstract The concept of a novel single probe feed cavity backed circularly polarized antenna based on substrate integrated waveguide technique has been investigated in this article. The proposed antenna provides high circularly polarized radiation performance and keeps advantages of low profile
